Context: The Vehicle Routing Problem is an NP-hard problem with a combination of varieties oftopics like logistics, optimization research and data mining. There is a vast need of vehicle routingsolutions in day to day like with different constraints. According to the requirements, this problem hasbeen a field of interest to a lot of researchers who incorporate scientific methods to combine andinnovate new solutions to optimize the routing. Being an np-hard problem, it is almost impossible tocompute the solutions to optimality but years of research on this area has paid off quite significantlya

Streszczenie:

Saving energy and increasing network lifetime are significant challenges in the field of Wireless Sensor Networks (WSNs). Energy-aware routing protocols have been introduced for WSNs to overcome limitations of WSN including limited power resources and difficulties renewing or recharging sensor nodes batteries. Furthermore, the potentially inhospitable environments of sensor locations, in some applications, such as the bottom of the ocean, or inside tornados also have to be considered. ZigBee is one of the latest communication standards designed for WSNs based on the IEEE 802.15.4 standard. The

A Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without the need for base stations or any other preexisting network infrastructure. In a peer-to-peer fashion, mobile nodes can communicate with each other by using wireless multihop communication. Due to its low cost, high flexibility, fast network establishment and self-reconfiguration, ad hoc networking has received much interest during the last ten years. However, without a fixed infrastructure, frequent path changes cause significant numbers of routing packets to discover new paths, leadi

In Wireless Sensor Networks (WSN), enhancing network lifetime is one of the critical challenges that should be considered during the network design. Sensor nodes exhaust their power in various activities such as sensing, processing and communication that represents the most energy-consuming and therefore should be managed to improve the network lifetime. The clustering has a significant task on network lifetime because sensor nodes consume a considerable amount of energy during the transmission and receiving in order to perform the clustering function stages.

Clustering is a popular routing technique in configuring Wireless Sensor Networks (WSNs). It can determine the communications between all nodes to collect data in an efficient manner. It handles the main challenge of energy-efficiency in WSNs, and can be used to re-configure the network according to changes in the nodes' conditions. This thesis contributes to the routing in WSNs by proposing an Energy-efficient and Load-balancing Cluster-based (ELC) routing algorithm for Carrier Sense Multiple Access (CSMA)-based WSNs.

It is discovered that a hierarchical routing protocol is ideal for a high node density. Due to the high bandwidth that is possibly available, with millimeter wave transmission, packets are used to keep links between nodes active and to control data packet congestion.

The paper presents a new cluster based routing algorithm that exploits the redundancy properties of the sensor networks in order to address the traditional problem of load balancing and energy efficiency in the WSNs.The algorithm makes use of the nodes in a sensor network of which area coverage is covered by the neighbours of the nodes and mark them as temporary cluster heads. The algorithm then forms two layers of multi hop communication. The bottom layer which involves intra cluster communication and the top layer which involves inter cluster communication involving the temporary cluster hea

A Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without the need for base stations or any other pre–existing network infrastructure. In a peer-to-peer fashion, mobile nodes can communicate with each other by using wireless multihop communication. Due to its low cost, high flexibility, fast network establishment and self-reconfiguration, ad hoc networking has received much interest during the last ten years. However, without a fixed infrastructure, frequent path changes cause significant numbers of routing packets to discover new paths, leadi

These hundreds or thousands of sensor nodes are spread across a geographical area to monitor ambient condition such as temperature, sound and light. These sensor nodes cooperate with each other to establish a sensing network that can provide access to surrounding information anytime, anywhere.

The current project aims to know the idiosyncrasies of ornamental ceramics sub-sector, from Alcobaça (Portugal). Later, it will be suggested a set of actions to improve it, trying to refrain its negative trend. This paper applies the idea of cluster, from Michael Porter, to the analyzed factories showing how they compete and cooperate at the same time. Consequently, it extends the referred concept to the possibility of an inter-firm umbrella brand, where all those enterprises can join efforts under a common strategy. This is particularly relevant, once many of them lack marketing pro-activity

The advancement in wireless communication and portable computing devices has made mobile computing possible. A mobile ad hoc network (MANET) is an infrastructureless network with no fixed routers, hosts, or wireless base stations.

Basically, WSN consists of a base station (BS) and a large number of sensor nodes. BS usually provides powerful capabilities for data collection, processing and store. However, each sensor node is limited by its battery power, and is responsible for collecting & transmitting the sensed data only. In order to reduce the energy consumpt

In a typical cluster-based WSN, sensor nodes are organized into clusters. Each cluster elects a cluster head (CH) node. The CH is responsible for collecting the sensed data from cluster members, aggregating data and transmitting data to the sink node via a multi-hop path through intermediate CHs. Thus, the use of cluster techniques not only shortens the transmission distances for sensor nodes but also reduces energy consumpti

碩士<br>國立交通大學<br>網路工程研究所<br>96<br>Routing in Delay Tolerance Network (DTN) is different from that in conventional networks because of high delivery delay. The main difference is that packets in DTN do not have end to end paths in the space domain. Therefore, we use space and time information to form a graph with links in the space and time domain, and apply the Dijkstra algorithm to find the shortest routing path. Because the graph contains links in time domain, the graph size is proportional with time. In DTN, the high delay leads to a larger graph, so the complexity of finding the shortest pa
