Abstract:
Community wireless mesh networks have emerged as cooperative initiatives to provide Internet Access in areas where traditional ISP costs are not affordable for the population. It is common in wireless mesh networks sharing several capacity limited Internet gateways to provide Internet access. As routing does not handle capacity planning, end-users have to select gateways in such a way that the overall capacity of all gateways could be used effectively. An efficient gateway selection should minimize the processing logic and measurements over the mesh network. Selecting a high performance gateway can also ensure that the overall network load is balanced. This paper presents RIMO, a standalone best-effort algorithm for client nodes to select their preferred gateway without interacting with other client nodes. RIMO-based selection matches the gateway performance of the reference brute-force and omniscient algorithms for 60% of the test duration while reducing the gateway performance measurement cost from a factor of n to 2. With a reduced overhead and high efficiency, the RIMO algorithm automates the aggregation of multiple Internet gateways in wireless mesh networks, which results in robust last mile Internet connectivity to people in vulnerable situation.

Abstract:
Extended Range Wide Area Network (LoRaWAN) has recently gained a lot of attention from the industrial and research community for dynamic Internet of Things (IoT) applications. IoT devices broadcast messages for neighbor gateways that deliver the message to the application server through an IP network. Hence, it is required to deploy LoRaWAN gateways, i.e., network planning, and optimization, in an environment while considering Operational Expenditure (OPEX) and Capital Expenditure (CAPEX) along with Quality of Service (QoS) requirements. In this article, we introduced a LoRaWAN gateway placement model for dynamic IoT applications called DPLACE. It divides the IoT devices into groups with some degree of similarity between them to allow for the placement of LoRaWAN gateways that can serve these devices in the best possible way. Specifically, DPLACE computes the number of LoRaWAN gateways based on the Gap statistics method. Afterward, DPLACE uses K-Means and Fuzzy C-means algorithms to calculate the LoRaWAN gateway placement. The simulations’ results proved the benefits of DPLACE compared to state-of-the-art LoRaWAN gateway placement models in terms of OPEX, CAPEX, and QoS.

Abstract:
Abstract The routing protocol for low-power and lossy networks (RPL) is a standard routing framework for Internet of Things (IoT). It supports multipoint-to-point (MP-to-P), point-to-point (P-to-P) and point-to-multipoint (P-to-MP) communications. It is known that RPL’s control overhead can result in the protocol’s poor performance in P-to-P and P-to-MP communications especially in its non-storing mode of operation. Here, we present a routing protocol for the Internet of Things (RIoT) that supports MP-to-P, P-to-P and P-to-MP communications. The protocol can construct P-to-P and P-to-MP routes with relatively lower control overhead. Another salient feature of RIoT is that it supports multiple gateways in the same network with an aim to reduce memory requirement for storing a forwarding table. Furthermore, RIoT is also capable of handling mobility-based IoT use cases. To facilitate communication among nodes connected to different gateways in the same network, here we also present an inter-gateway communication mechanism. We implemented RIoT in the Contiki operating system, and it is extensively evaluated using emulation and real testbed-based experiments. We analyzed the impact of the number of gateways, radio duty cycling (RDC) and mobility on the routing protocols’ performance. Our results demonstrate that either with or without RDC RIoT demonstrates statistically significantly better packet delivery ratio, per-packet end-to-end delay and control overhead compared to the RPL-based protocol. RIoT’s multi-gateway communication architecture substantially reduces the memory requirement to store a forwarding table. Our results also demonstrate that multiple gateways in a network reduce the network partitioning problem in mobile scenarios. Hence, RIoT also demonstrates better performance in mobile scenarios compared to the RPL-based protocol.

Abstract:
Integrating MANETs (Mobile Ad-hoc Networks) nodes to the Internet require either a connection to the Internet or they can connect to the Internet through the Internet gateways. For the second case if a node in a MANET has discover the gateway to connect to the fixed hosts in the Internet and it can be done either by broadcasting a gateway discovery request message initiated by nodes itself or by broadcasting periodic gateway advertisement messages from the gateways. End to end packet delay and throughput are strongly dependent on the time needed to discover the gateways.Nodes in a MANET use number of hops as metric to select a path to a gateway, if all the nodes select its nearest gateway to access the Internet then there may be situations when the network performance degrades because some nodes along the path have too many packets waiting in the queue.This paper presents a novel solution to access internet through mobile nodes in ad hoc network. Here the gateway replies with an advertisement message which is broadcasted to the whole network instead of sending a unicast reply to the requesting node. The traffic load taken into account along a path in addition with minimum hop count to select an efficient gateway. The AODV routing protocol has been used for routing in the MANET domain.A new strategy of gateway discovery was investigated and impact of new metric on the gateway selection in NS-2 was observed. Simulation results show that the proposed scheme outperforms over the existing scheme with high throughput and lower end to end delay.

Abstract:
The Internet of Things (IoT) is a distributed system that connects everything via internet. IoT infrastructure contains multiple resources and gateways. In such a system, the problem of optimizing IoT resource allocation and scheduling (IRAS) is vital, because resource allocation (RA) and scheduling deals with the mapping between recourses and gateways and is also responsible for optimally allocating resources to available gateways. In the IoT environment, a gateway may face hundreds of resources to connect. Therefore, manual resource allocation and scheduling is not possible. In this paper, the whale optimization algorithm (WOA) is used to solve the RA problem in IoT with the aim of optimal RA and reducing the total communication cost between resources and gateways. The proposed algorithm has been compared to the other existing algorithms. Results indicate the proper performance of the proposed algorithm. Based on various benchmarks, the proposed method, in terms of “total communication cost”, is better than other ones.

Abstract:
Considering the complex network characteristics of mobile ad hoc network, a new MANET accessing Internet model was proposed. In this model, transmit power was adjusted by residual energy of the node, and added long-range edge in network to make MANET with more obvious small world characteristics. On this basis, the paper proposed a gateway programming model, which introduced a decision node to harmonize the utilization of gateways and routes. The model, as the basis of the gateway configuration, optimized the placement of the gateway. The simulation results indicate that the performance of delay, overhead and throughput has promoted after the model was introduced, which validates the validity of the model.

Abstract:
A mobile ad hoc network (MANET) is an autonomous collection of independent nodes cooperating together to form an infrastructure less network spontaneously. For increasing usability of MANET domain which finds application in natural disaster such as earthquake, floods etc. it is also desired to be connected with Internet through Internet gateways. Therefore, an efficient gateway discovery mechanism is required for MANET-Internet integration. Existing schemes use one or multiple parameters for optimal selection of gateway which causes a particular gateway to be selected many times which results in higher delay latency and packet drops due to prevailing congestion at a particular gateway. To avoid this situation, the authors have utilized the potential of fuzzy logic to ascertain the decision of load balancing at the Internet gateway. Besides this, their scheme also incorporates an effective adaptive gateway discovery mechanism. Consequently, enhanced performance is achieved as compared to existing state-of-the-art related schemes. The proposed approach is evaluated by simulation and analytical validation.

Abstract:
Aiming at such an application of wireless mesh sensor network (WMSN) so that continuous flow is transmitted, this paper proposes a model "maximum lifetime maximum throughput" based on the ant colony algorithm and minimum cost maximum flow method to address the routing issue between sensor nodes and multiple gateways in WMSN. In the proposed model, a sensor node is allowed to connect through more than one of the available gateways to the Internet. Between the source node and each gateway, a routing path with minimum link cost and maximum available bandwidth is attempted to be found. Then, considering the bandwidth demand of the flow originating from the sensor node and the available bandwidth on each optimal path, the flow traffic is allocated to appropriate gateways. Simulation results have shown that the proposed model not only prolongs network lifetime, but also improves network throughput.

Abstract:
Multi-hop wireless ad hoc wireless networks have no fixed network infrastructure. Such a network consists of multiple nodes that maintain network connectivity through wireless links. Additionally, these nodes may be mobile and thus the topology of the network may change with time. It will be useful if the nodes in this network could communicate with the Internet; this can be done via gateways which in turn interconnect to the Internet. This functionality requires that the nodes in the ad hoc network to discover the gateway, using a gateway discovery protocol. However, a limiting factor (particularly for mobile nodes) is suing their limited energy supply provided by batteries. In order to understand the potential effect this thesis considers two key areas: internetworking between a multi-hop mobile wireless ad hoc network and the Internet and the energy utilization as a function of number of gateways and the mobility pattern of nodes. Using simulation on various mobility patterns and networks density scenarios, we show that increase the number of gateways in ad hoc network significantly improves the power efficiency of mobile node and therefore prevent network partition due to death nodes. The thesis also discusses about the impact of different environment and mobility patterns on the power consumption of mobile nodes which is a very important factor in the building and deployment of the cost-effective high performance wireless ad hoc networks.

Mestrado em Engenharia Electrónica e Telecomunicações
The need to be always connected to the world is now a reality in most countries; people want to be always reachable, want to be always connected to what is happening around them, in their city, worldwide. With the sharp increase in the number of users of social networks, the watchword of today is to share, from comments, photos or even videos, the important thing is to be connected to the world. Also in this area, vehicular networks, which have been initially designed to support security applications in order to improve road traffic, are now seen more as a way to provide entertainment to its users. And the best way to engage users is to give them what they use most in their daily life, Internet access. If the vehicles are able to share connection between themselves and with their passengers, this would be a breakthrough for this type of network. However, many problems still affect the vehicular networks: they are expected to be slowly deployed, so that the first nodes of the network will primarily use the already existing connections along the road, as an example, WI-FI hotspots. Due to the high mobility of the vehicles and hence the network, it is expected a significant number of handovers between access points along the route. Without an appropriate mobility protocol the loss of connection and session would be common. In order to make the process more transparent to the user, a network mobility protocol is required, not only to provide mobility to the vehicle, but also to its passengers. The aim of this MSc Dissertation focuses on the study of the types of existing mobility protocols and discusses the possibility of adapting them to the vehicular networks and to the communication between vehicles and their passengers. In this regard, it was decided to use the Proxy Mobile IPv6 (PMIPv6) for handover between base stations, and Nemo - PMIPv6 for handover of vehicular networks between fixed and mobile stations. These mechanisms have been extended and implemented to provide mobility in a vehicular network. To keep the link with the best quality possible along the path, it is also required an entity to monitor available access networks forcing the connection to the one that has better conditions, through a connection manager. The tests performed in the laboratory and on the road focused on the access technology IEEE 802.11p, a technology designed specifically for vehicle networks, and IEEE 802.11g, one of the technologies used today. The results of handovers performed on various road scenarios show that the mechanisms developed allow to provide transparent mobility for both vehicles and passengers, even in mobility between networks with a different number of vehicles to the infrastructure.
A necessidade de estar em permanente ligação com o mundo é já uma realidade na grande maioria dos países; as pessoas querem estar sempre contactáveis, querem estar sempre ligadas ao que se passa à sua volta, na sua cidade, em todo o mundo. Com o forte aumento do número de utilizadores das redes sociais a palavra de ordem da atualidade é partilhar, desde comentários, fotos ou até vídeos, o importante é estar ligado ao mundo. Também nesse sentido têm vindo a ser desenvolvidas as redes veiculares. Inicialmente pensadas para suportar aplicações de segurança de forma a melhorar o tráfego rodoviário são agora vistas como mais uma forma de proporcionar entretenimento aos seus utilizadores. E a melhor forma de cativar os utilizadores é dar-Ihes aquilo que mais utilizam no seu dia a dia, o accesso à Internet. Se os veículos forem capazes de partilhar ligação entre si e para com os seus passageiros, esse será um avanço importante para este tipo de redes. Contudo, muitos desafios afetam ainda as redes veiculares: prevê-se que tenham uma introdução gradual no mercado, mas lenta, pelo que os primeiros constituintes da rede terão sobretudo de usufruir das ligações já existentes ao longo da estrada, por exemplo, hotspots WI-FI. Devido à grande mobilidade dos veículos e consequentemente da rede prevê-se que o número de handovers entre pontos de accesso ao longo do trajeto seja elevado. Sem um protocolo de mobilidade apropriado a perda de ligação e sessão seria frequente. De forma a tornar o processo mais transparente para o utilizador é necessário um protocolo de mobilidade de rede capaz de não só fornecer mobilidade ao veículo, como também aos seus passageiros. O objetivo desta Dissertação de Mestrado centra-se no estudo dos tipos de protocolos de mobilidade já existentes e analisar a possibilidade de os adaptar para redes veiculares e comunicação entre veículos e para os seus passageiros. Neste sentido decidiu-se utilizar como base o protocolo Proxy Mobile IP (PMIPv6) para handover entre estações fixas, e o Nemo - PMIPv6 para handover de redes de veículos entre estações fixas e móveis. Estes mecanismos foram extendidos e implementados para proporcionarem mobilidade numa rede veicular. Para a ligação se manter com a melhor qualidade possível ao longo do trajeto é também necessário uma entidade que monitorize as redes de accesso disponíveis forçando a ligação do sistema à rede que apresentar melhores condições, através de um gestor de ligações. Os testes efetuados em laboratório e na estrada incidiram sobre as tecnologias de accesso IEEE 802.llp, uma tecnologia desenvolvida especialmente para as redes veiculares, e o IEEE 802.11g, uma das tecnologias mais utilizadas atualmente. Os resultados de handovers realizados em vários cenários de estrada mostram que os mecanismos desenvolvidos permitem fornecer mobilidade transparente dos veículos e seus passageiros, mesmo em mobilidade entre redes com um número diferente de veículos até à infra-estrutura.

Mestrado em Engenharia Electrónica e Telecomunicações
Com o grande crescimento das comunicações móveis e fixas, o acesso à Internet tornou-se cada vez mais numa exigência, colocando à industria das Telecomunicações, especialmente aos operadores, grandes desafios. Serviços comuns como chamadas de voz, podem agora ser oferecidos pelos Internet Service Providers (ISPs) aos seus clientes sobre a forma de serviço Voice over IP (VoIP). Este serviço deixou de ser exclusivo das redes Public Switched Telephone Network/Integrated Services Digital Network (PSTN/ISDN) e passou a ser fornecido também na Internet. Mas devido à necessidade de manter as tradicionais redes PSTN/ISDN, houve a necessidade de criar um ambiente de convergência, não só para estas redes mas também para outros tipos de redes de acesso, independentemente da tecnologia. É neste campo que os organismos de normalização e os operadores têm dado os seus contributos, criando uma rede de controlo e de transporte comum baseada em IP para a convergência de serviços. Inicialmente o 3rd Generation Partnership Project (3GPP) definiu uma arquitectura de convergência móvel com a rede IP, constituída por elementos de controlo, transporte e serviço, de nome IP Multimedia Subsystem (IMS). Mais tarde, esta arquitectura serviu de base (core) para o grupo TISPAN do European Telecommunications Standard Institute (ETSI) na normalização das Redes de Próxima Geração. Esta Dissertação pretende dar uma resposta à convergência fixo-móvel no âmbito da arquitectura PSTN/ISDN Emulation Subsystem (PES) do TISPAN. Este sistema permite que todos os clientes de uma Rede de Próxima Geração de um operador acedam a serviços das redes PSTN/ISDN e Digital Subscriber Line (DSL) de uma forma simples e imperceptível. Com este intuito foram desenvolvidos cenários de testes para os sistemas Trunking e de Acesso da arquitectura PES, tendo como objectivo final a sua integração na plataforma de próxima geração Service Handling on ip NETworks (SHipNET). Esta Dissertação experimenta várias situações reais de chamadas de voz sobre os cenários de testes, e inicia a implementação de um novo elemento definido para a arquitectura PES, Access Gateway Control Function (AGCF), para o controlo de Media Gateways nas redes de Acesso. ABSTRACT: With the big growth of mobile and fixed communications, Internet access has become a requirement, putting the telecommunication industry, and especially the operators, in front of a major challenge. Services such as voice calls can now be offered by Internet Service Providers (ISPs) to their customers. This service is no longer exclusive of Public Switched Telephone Network/Integrated Services Digital Network (PSTN/ISDN) and is now provided also through the Internet. But, because of the need to maintain the traditional PSTN/ISDN networks, there was a need to create a convergence, not only for these networks but also for other types of access networks, regardless of technology. The standards bodies and operators have made their contributions to create a network of control and transport policy, based on IP, for the services convergence. In the beginning the 3rd Generation Partnership Project (3GPP) defined an architecture for mobile convergence with IP network, made up of control, transport and service elements, called IP Multimedia Subsystem (IMS). Later, the core IMS served the ETSI TISPAN group in standardization of Next Generation Networks. This thesis aims to give an answer for fixed-mobile convergence within the architecture defined by TISPAN PSTN/ISDN Emulation Subsystem (PES). This system, formed by a Trunking, originally defined by the 3GPP IMS, and Access part, allows all customers of a Next Generation Network operator, access to PSTN/ISDN and Digital Subscriber Line (DSL) network services in a simple way. With this purpose, scenarios were developed for Trunking and Access systems of PES arquitecture, with the goal to integrate into the next generation platform Service Handling on ip NETworks (SHipNET). This thesis tests several real situations of voice calls on testing scenarios, and begins the implementation of a new element defined for PES arquitecture, Access Gateway Control Function (AGCF), for Media Gateways control purpose in access networks.

Abstract:
La virtualizzazione permette a diverse applicazioni di condividere lo stesso dispositivo IoT. Tuttavia, in ambienti eterogenei, reti di dispositivi IoT virtualizzati fanno emergere nuove sfide, come la necessità di fornire on-the-fly e in maniera dinamica, elastica e scalabile, gateway. NFV è un paradigma progettato per affrontare queste nuove sfide. Esso sfrutta tecnologie di virtualizzazione standard per consolidare specifici elementi di rete su generico hardware commerciale. Questa tesi presenta un'architettura NFV per gateway IoT distribuiti, nella quale istanze software dei moduli dei gateway sono ospitate su un'infrastruttura NFV distribuita, la quale è operata e gestita da un IoT gateway Provider. Considereremo diversi IoT Provider, ciascuno con le proprie marche, o loro combinazioni, di sensori e attuatori/robot. Ipotizzeremo che gli ambienti dei provider siano geograficamente distribuiti, per un'efficiente copertura di regioni estese. I sensori e gli attuatori possono essere utilizzati da una varietà di applicazioni, ciascuna delle quali può avere diversi requisiti per interfacce e QoS (latenza, throughput, consumi, ecc...). L'infrastruttura NFV consente di effettuare un deployment elastico, dinamico e scalabile dei moduli gateway in questo ambiente eterogeneo e distribuito. Inoltre, l'architettura proposta è in grado di riutilizzare moduli il cui deployment è stato precedentemente compiuto. Ciò è ottenuto attraverso Service Function Chaining e un'orchestrazione dinamica a runtime. Infine, presenteremo un prototipo basato sulla piattaforma OpenStack.

O cenário introduzido pela Internet das Coisas potencializa a criação de um novo conjunto de aplicações e serviços, onde diversos dispositivos interagem entre si através da Internet. Esse cenário viabiliza o advento de novas tecnologias de transmissão sem fio de baixo consumo, como o Bluetooth Low-Energy (BLE), as quais viabilizam a criação de redes pessoais (PAN) sem fio. Em paralelo, com a crescente disponibilidade de Dispositivos Pessoais de Saúde com capacidade de comunicação, um cenário onde informações de saúde podem ser disponibilizadas na Internet surge, viabilizando a criação de sistemas de Saúde Conectada. Entretanto, ao viabilizar a criação de redes PAN interconectando diversos dispositivos, a Qualidade de Serviço na rede necessária para o correto funcionamento desses dispositivos de saúde pode ser afetada, dado que redes PAN BLE não oferecem mecanismos para a diferenciação da Qualidade de Serviço entre os dispositivos conectados. Considerando esse contexto de compartilhamento de uma rede PAN entre diversos dispositivos, nesse trabalho propõe-se uma abordagem para o controle do fluxo adaptativo em Gateways BLE utilizando um mecanismo de distribuição de créditos temporal entre os clientes de uma rede PAN. Para essa priorização, informações fornecidas por aplicações são utilizadas para a distribuição e configuração dos parâmetros de conectividade dos dispositivos da rede PAN. Também são apresentados detalhes sobre o projeto e evolução arquitetural do controlador adaptativo, detalhando suas características de controle de fluxo com prioridade temporal. São apresentados resultados experimentais do funcionamento do controlador adaptativo em diferentes cenários. Esses resultados demonstram que o mesmo é capaz de garantir a Qualidade de Serviço de rede necessária para dispositivos específicos em um ambiente compartilhado. Para a validação desse trabalho em um cenário mais amplo, é apresentada uma arquitetura para Sistemas de Monitoramento Remoto de Pacientes padronizado para a Internet das Coisas. Esse sistema serve como base para a implantação e avaliação experimental do controlador de fluxo adaptativo em um Smart-Gateways BLE, onde informações de serviços e aplicações em saúde são utilizadas para priorizar Dispositivos Pessoais de Saúde a depender do seu contexto de uso.
The Internet of Things paradigm enables a new set of applications and services to be available in the Internet. This scenario makes possible the development of new low-power communication technologies, such asBluetooth Low-Energy (BLE), which creates wireless Personal Area Networks (PAN). At the same time, the rising availability of Personal Health Devices (PHD) capable of PAN communication and the desire of keeping a high quality of live are the ingredients of the Connected Health vision. However, as the number of PHDs increase, the number of other peripherals connected in the PAN also increases. Therefore, PHDs are now competing for medium access with other devices, decreasing the network Quality of Service of health applications in the BLE PAN, as these networks do not guarantee Quality of Service requirements for connected devices. In this context, where a BLEPAN is shared with multiple devices, it is where this work is immersed. In this work is presented an approach for adaptive flow-control of BLE Gateways using a temporal credit distribution mechanism between clients in a PAN. For this distribution, application context information is used for network prioritization and parameter configuration of PAN devices. In this work is detailed how the adaptive flow-control was designed and how was its architectural evolution, detailing how its temporal mechanism works. Experimental results are presented showing the controller behavior in different scenarios. These results show that using the proposed approach it is possible to guarantee Quality of Service requirements for target devices using a prioritization process in a shared medium. In order to validate this work in a broad scenario, it is also presented a standard-based Remote Patient Monitoring System architecture for the Internet of Things. This system is used as base infrastructure for prioritization of PHDs connections based on their state and requirements by the use of a Smart BLE Gateway. An implementation was developed showing the relevance of the problem and how a BLE adaptive controller can assist in the prioritization of devices in the context of healthcare services and applications.
