Abstract:
The developments of wireless networks have directed to search for opportunities of a broad diversity of improved and new networking contributions. Wireless Asynchronous Transfer Mode (ATM) is a non-synchronous or random mode of transferring information. The advantages of circuit switching include dedicated connections and guaranteed traffic parameters and the benefits of packet switching are the efficiency at the physical layer and a more cost-effective design. ATM is the only protocol that offers the best of both communication methods. Although the Variable Bit-Rate (VBR) transmission presents a promising prospective of stable data quality, it is usually accompanied by network traffic overload and cell packet loss, which extensively weakens that potential. This work overcomes these concerns by developing a switching-based multiple access control model to improve the data transmission performance of wireless ATM. Therefore, this work discusses the effectiveness of the developed approach to minimize the cell packet losses and network traffic overload in wireless ATM. Three control access is processed; polling, token passing, and reservation algorithms for collision avoidance. The reservation stage reserves the data before sending, which includes two timeline intervals; a fixed-time reservation period, and variable data transmission interval. Using OPNET 10.5, the results show that the presented switching-based multiple access control model can achieve a throughput value of 98.3 %, data transmission delay of about 40.2 ms, and 0.024 % of packet losses during data transmission between the source and destination. It is demonstrated that the introduced method effectively transmits information without creating any network complexity and delay

Abstract:
Sensors in the Internet of Things (IoT) generate large amounts of data, which requires high-speed data transmission. In order to achieve the parallel transmissions of the wireless sensor network on the transmission layer, the performance of stream control transmission protocol (SCTP) and transmission control protocol (TCP) in the wireless sensor network under different packet error rates was simulated and compared. A dynamic multipath handover method for SCTP (MS-SCTP) was proposed to improve the transmission performance, which selects the transmission path according to the packet error rate and the retransmission ratio in the sender’s buffer. The TCP and SCTP protocol switching method (TCP-SCTP) was proposed to detect the current network traffic and adjust the MS-SCTP or TCP method. Analysis and simulation results show that MS-SCTP and TCP-SCTP could improve network throughput and reduce packet loss rate. MS-SCTP and TCP-SCTP can be combined with other technologies and channel allocation algorithms to improve network traffic.

Abstract:
Efficient transmission of medical information is an emerging area of telecommunication engineering because it conveys critical data about a patient’s state and vital measurements. Consequently, it is required that such transmissions be accelerated and errorless. This requirement is beyond the norm of only scheduling users at a Base Station but calls for the provisioning of guaranteed bandwidth for transmission of these critical medical data. To achieve this, there is a need to develop a scheduling scheme that will prioritize all forms of Telemedicine traffic over regular traffic at the Base Station. But there is also the need to measure, evaluate and quantify the impact of the developed scheduling scheme on telemedicine traffic transmission in cellular networks in terms of the throughputs attained. To address these problems, priority and non-priority based scheduling algorithms for telemedicine traffic transmission were developed and simulated using MATLAB 8.1.0 software and the impact of the developed algorithm on telemedicine traffic transmission was evaluated. The result represents a significant increase in telemedicine user’s throughputs with a priority scheduling scheme. Over 20 rounds, the impact of packet sizes, traffic load conditions and codec rates on the average throughputs of telemedicine traffics were studied and discussed.

Abstract:
In the existing network-layered architectural stack of Cognitive Radio Ad Hoc Network (CRAHN), channel selection is performed at the Medium Access Control (MAC) layer. However, routing is done on the network layer. Due to this limitation, the Secondary/Unlicensed Users (SUs) need to access the channel information from the MAC layer whenever the channel switching event occurred during the data transmission. This issue delayed the channel selection process during the immediate routing decision for the channel switching event to continue the transmission. In this paper, a protocol is proposed to implement the channel selection decisions at the network layer during the routing process. The decision is based on past and expected future routing decisions of Primary Users (PUs). A learning agent operating in the cross-layer mode of the network-layered architectural stack is implemented in the spectrum mobility manager to pass the channel information to the network layer. This information is originated at the MAC layer. The channel selection is performed on the basis of reinforcement learning algorithms such as No-External Regret Learning, Q-Learning, and Learning Automata. This leads to minimizing the channel switching events and user interferences in the Reinforcement Learning- (RL-) based routing protocol. Simulations are conducted using Cognitive Radio Cognitive Network simulator based on Network Simulator (NS-2). The simulation results showed that the proposed routing protocol performed better than all the other comparative routing protocols in terms of number of channel switching events, average data rate, packet collision, packet loss, and end-to-end delay. The proposed routing protocol implies the improved Quality of Service (QoS) of the delay sensitive and real-time networks such as Cellular and Tele Vision (TV) networks.

Abstract:
A technique of synthesis of a wireless digital communication network with package switching, providing transfer of video messages of real time scale between elements of multipurpose information-operating system in conditions of high failure rate of central elements, is considered. As conceptual model of a telecommunication network – the network of the mixed structure, including multipurpose devices, constructed on the basis of standards of a broadband radio access with switching of packages and two interconnected levels of network interaction of elements (local and main) is accepted. The technique of synthesis of a wireless network is based on the multilevel, combined adaptation of a telecommunication network in the conditions of refusals of central elements, which primary goal is rational change of parameters, functions of network elements in close interrelation with purposeful transformation of structure of telecommunication system subnetworks. The main objective of carrying out the combined adaptation of the network consists in achievement of necessary throughput of communication system depending on degree of failure rate of central elements. Properties of multilevel adaptation were investigated in the course of realization of the combined (structurally-parametrical) synthesis with use of the aggregate approach of modelling of difficult technical systems. Efficiency of the specified technique is proven by the results of the imitating experiment with use of the aggregate model of a wireless network of data transmission with switching of packages, obtained previously. The experimental data, received at natural research of networks of a broadband radio communication on the basis of standards 802.11 b/g/n, have shown, that time of processing of packages of a message essentially depends on use of existing ways of adaptation. In particular, application of effective algorithms of adaptation (both parametrical and structural) will allow to reduce the time of finding of details (packages) in broadband communication devices by several times and, thereby, to provide demanded throughput of the network functioning in the conditions of refusals of central elements.

Abstract:
In the process of carrying out search and rescue operations and emergency response measures, organization of manpower and equipment management based on ensuring effective information exchange is of great importance. Moreover, tasks are often carried out in conditions of inoperative or absent telecommunication infrastructure and possible destructive external influences. In such situations, for the transfer of information, it is preferable to deploy a mobile ad hoc network, which has an arbitrary decentralized topology and is able to operate without base stations. In order to ensure the transmission of streaming data with the required quality in wireless packet-switched networks, various algorithms for the dynamic distribution and reservation of channel resources have been developed. However, insufficient attention has been paid to substantiating the duration of the transmission of streams of audio information in a mobile ad hoc network. The article presents the results of the development and research of an algorithm for obtaining the recommended duration of sessions for transmitting voice information streams to support decision-making to ensure the effectiveness of audio communications in a mobile ad hoc network. The recommended duration of the communication session depends on the limit number of packets in the audio stream, the calculation of which is based on the use of mathematical models to estimate the average volume of a multimedia message, the transmission of which can be carried out with the required quality for the given characteristics of the network. Implementation of the proposed algorithm will allow users of a mobile ad hoc network to receive messages about the recommended duration of audio communication sessions.

Abstract:
The article considers the issues of statistical modeling of traffic in telecommunication networks with packet switching. The simulation results are used in the development of network technical condition management systems, in particular, diagnostics, troubleshooting and network configuration management. The peculiarities of congestion control of separate network segments are emphasized. With improper analysis the overload condition can be mistaken for equipment failure. Therefore, control and elimination of congestion is a statistical task. The concept of end-to-end network diagnostics is considered. This concept provides for effective assessment of the quality of functioning of all network components taking into account their interrelationships. The main issues are the interaction of equipment, inefficient configuration, improper network organization and user operation. Methods of traffic statistical control characteristics based on perforated and marker bucket algorithms are analyzed. A feature of these algorithms is the formation of a strict output stream at a rate that does not depend on the non-uniformity of the input stream. The possibility of improving the token bucket algorithm by adapting to changes in the statistical characteristics of traffic is shown. To solve this problem, statistical mathematical models of network traffic are built. Data traffic circulating in telecommunication networks by packet switching has self-similar (fractal) properties. The self-similar process retains its properties when considered at different time scales (invariance to scale changes). The degree of statistical stability of the process with multiple scaling is determined by the Hirst parameter (the self-similarity parameter). Graphs of statistical characteristics of low-speed and high-speed data traffic are obtained. Their comparative analysis is carried out.

Abstract:
Chapter 7 exposes the algorithms that are the foundations of the Internet. The Internet relies on “packet-switching” to transfer data between computers. Messages are broken into ‘‘packets’’ of data and these packets are routed across the network in a series of hops between linked computers. The advantage of packet-switching is that the network is easily extended and is robust to isolated computer failures. Data sent on the Internet is protected from errors by means of an algorithm invented by Richard Hamming. His algorithm adds information to packets, enabling receiving computers to detect and correct transmission errors. Communication on the Internet is secured by means of an algorithm published in 1977. The RSA algorithm relies on the properties of large prime numbers to prevent eavesdroppers from reading encrypted messages.

Abstract:
The last two decades, after the telecommunication and computer technology convergence, the world of telecommunication applications has changed dramatically. The traffic needs of the customers have moved from circuit switched applications towards packet switched applications (Cox, 1995). Data traffic, with the characteristics of information transmission in the form of packets and the bursty flow characteristics rather than constant rate, nowadays accounts for slightly more than 60% of the traffic that is transmitted over the backbone telecommunication networks (Esmailzadeh, Nakagawa, & Jones, 2003). In addition to data traffic, multimedia applications like video calls, IP TV, and multimedia messaging traffic (variable rate with real time constraints) was made possible by low cost video digitizing equipment (Houssos, Alonistioti, Merakos, Mohyeldin, Dillinger, Fahrmair, & Schoenmakers, 2003). Different Radio Access Technology (RAT) networks offer different services to their subscribers. This is a big problem for the multimedia industry since it poses certain constraints to the subscribers regarding specific technology handsets. The ideal solution might be a unified handset with a unified service subscriber identity module (SIM) card (Louvros & Iossifides, 2004). This handset should be able to access the service by any radio access network, like Global System Mobile (GSM) (Siegmund, Redl, Weber, & Oliphant, 1995), General Packet Radio System (GPRS), Universal Mobile Telecommunications System (UMTS), and IEEE802.11 standard (WiFi or WLAN) towards a common core platform. In order to achieve such a unification, the service request should be seamless to the radio access technology network and the core platform should support certain protocols to provide again seamless to the user access to the requested service. Such a platform is already designed and is known as the soft-switch solution. The idea behind the soft-switch solution is the layering of the core network management procedures (mobility management, call control, session management, charging) in such a way that the operator can support all requests as a unified routing process. Moreover the operator can deploy its core switch and transmission network based on a common backbone, designed according to the 3GPP standards on IP or ATM infrastructure, and also to be able to accommodate in the future any new radio access technology network simply and without any serious rearrangement of the existing backbone, thus eliminating cost implementation. Asynchronous Transfer Mode (ATM) technology is proposed by the telecommunication industry to accommodate multiple traffic types (packet and voice) in a high speed wire-line backbone network. Briefly, ATM is based on very fast (on the order of 2.5 Gbits/sec or higher (Q.2931 ATM Network Signaling Specification, ITU)) packet switching technology with 53 byte long packets called cells being transmitted through wireline networks running usually on fiber optical equipment (Louvros, Karaboulas, Iossifides, & Kotsopoulos, 2003).
