Wireless Mesh

The spread out of wireless mesh network has made possible the extended range of communication network that are impractical due to environmental changes in a wired access point, these wireless mesh network does not require much competence to set it up as it can be set very fast at a cheap rate, and the conveyancing of messages in it happens by selecting the shortest path, these wireless mesh built-in with irrepressible and invulnerable identities come with an endurance to temporary congestion and individual node failure. This results in an architecture providing a better coverage, flaw indulgent with higher bandwidth compared to other wireless distributed systems. But faces the limitation on power conservation. The battery activated mesh nodes loses their resources on perception, processing and transmission of the data’s, though these batteries or accumulators comes with energy regaining capability still draw backs show up as their nature of energy regaining are unexposed. So the performance analysis of fly wireless network which proposes a uninterrupted wireless mesh networks aims at providing a best measure of performance that is the best quality of service on the meshwork by providing an improved energy gleaning using potency segregation (IGPS) which empowers each node to have self- contained accumulation of energy achieving heightened adaption with energy consumption kept at a minimum. The gross functioning of the proposed is examined on the bases of delay and packet loss to prove the quality of service acquired.

Call Admission

The unpredictable nature of the wireless network and exponential growth in traffics with different quality of service requirements has led hardware complexity to escalate. In order to effectively control and manage the network traffics, there is a need for intelligent call admission control (CAC) in admitting traffics into the wireless network that provides necessary quality of service. In this paper, we propose a fuzzy logic partition-based call admission control (FZ CAC). The scheme primarily partitions the total link bandwidth into three which corresponds to constant bit rate (CBR), variable bit rate (VBR) and handover (HO) services. The fuzzy logic admission control scheme was implemented in the HO portion to intelligently keep dropping probability as low as possible based on the available bandwidth. Simulation results showed that the proposed approach outperformed both partition-based CAC (PB CAC) and conventional bandwidth allocation CAC (CB CAC).

Medical Quality

It is well known that the evolution of 4G-based mobile multimedia network systems will contribute significantly to future m-health applications that require high bandwidth, high data rates, and more critically better Quality of service and quality of experience. The key to the successful implementation of these emerging applications is the compatibility of emerging broadband wireless networks such as mobile WiMAX, HSUPA, and LTE networks with future m-health systems. Most recently, the concept of 4G-health is introduced. This is defined as the evolution of m-health towards targeted personalized medical systems with adaptable functionalities and compatibility with future 4G communications and network technologies. This new concept represents the evolution of m-health toward 4G mobility. It will have new challenges especially from the next generation of mobile communications and networks perspective and in particular from relevant quality of service and quality of experience issues. This chapter presents some of these challenges and illustrates the importance of the new concepts of medical Quality of Service (m-QoS) and medical Quality of Experience (m-QoE) for 4G-health systems. The chapter also presents a validation scenario of these concepts for medical video streaming application as a typical 4G-health scenario.

Contention Period

In this paper the IEEE 802.16 standard based Mobile WiMAX (Worldwide Interoperability for Microwave Access) system is investigated for the purpose of Quality of Service provisioning. As a potential solution, scheduling algorithms have been taken into major concern. Within the pool of scheduling algorithms and for the purpose Contention based bandwidth request resolution, the Modified Contention Based BW Resolution algorithm (MCB-BWR-Scheme) is proposed. Supported by the fact that the standard does not emphasize a specific scheduling algorithm for contention period based services, therefore, the choice of the scheduling algorithm for the WiMAX systems is very important. There are several scheduling algorithms for WiMAX in the literature, however, studies show that an efficient, fair and robust scheduling algorithm for WiMAX systems is still an open research area and hence a well thought out algorithm will be of great contribution to the area under investigation. Results from the OPNET Modeler simulation program show that the adjusted algorithm works well with delay and throughput constraints. It is also in consistent with the quality of service demands of the video and voice traffic.

The scope of development and research in the field of wireless mesh networks (WMN) is wide open and the focus has also been widened from simple channel assignment to multicast routing further moving towards providing quality of service (QoS) to the end users. The nodes in the network are of multi radio multi channel (MRMC) model. The efficiency of the network is termed as quality of service. For providing the QoS to the end users different techniques have been evolved which caters situations as QoS provisioning in the channel assignment phase, QoS provisioning in the multicast routing phase, and QoS provisioning in the channel assignment and multicast routing phase. This chapter presents a detailed study of QoS provisioning in WMN. It also classifies the techniques as: QoS provision in channel assignment, QoS provision in multicast routing and QoS provision in channel assignment as well as multicast routing.
