Available in PDF, EPUB and Kindle. Book excerpt: Overview and Goals Wireless communication technologies are undergoing rapid advancements. The last few years have experienced a steep growth in research in the area of wireless sensor networks (WSNs). In WSNs, communication takes place with the help of spatially distributedautonomoussensornodesequippedtosensespeci?cinformation. WSNs, especially the ones that have gained much popularity in the recent years, are, ty- cally, ad hoc in nature and they inherit many characteristics/features of wireless ad hoc networks such as the ability for infrastructure-less setup, minimal or no reliance on network planning, and the ability of the nodes to self-organize and self-con?gure without the involvement of a centralized network manager, router, access point, or a switch. These features help to set up WSNs fast in situations where there is no existing network setup or in times when setting up a ?xed infrastructure network is considered infeasible, for example, in times of emergency or during relief - erations. WSNs ?nd a variety of applications in both the military and the civilian population worldwide such as in cases of enemy intrusion in the battle?eld, object tracking, habitat monitoring, patient monitoring, ?re detection, and so on. Even though sensor networks have emerged to be attractive and they hold great promises for our future, there are several challenges that need to be addressed. Some of the well-known challenges are attributed to issues relating to coverage and deployment, scalability, quality-of-service, size, computational power, energy ef?ciency, and security.

Book excerpt: Network Management can be defined as the deployment, integration, and coordination of hardware, software, and human elements to monitor, analyze, evaluate, and control network resources, in order to meet the operational performance and Quality of Service requirements in a network. It includes the ability to monitor and gather data from various distributed network entities, and utilize this information for the purpose of maintaining network performance. It includes performance management, fault management, and network configuration and accounting. Wireless Mesh Networks (WMNs) are multi-hop wireless networks that have become increasingly prevalent over the last few years. They are being applied to an increasing number of applications ranging from municipal and enterprise networks to wildlife monitoring. However, apart from the usual intricacies involved in a wireless network, WMNs involve data transfer over multiple wireless hops, which adds to the complexity of maintaining network performance. The increasing popularity of WMNs calls for new and effective management schemes to be in place. We focus on three core areas within network management. We first investigate the aspect of efficient monitoring in WMNs. This study is a crucial first step in our research, as it enables us to identify the impact of monitoring overheads on data traffic. The second aspect we study is that of resource control. Based on the inferences from our previous study, we implement passive monitoring modules in order to measure various network parameters. We implement an admission control scheme, based on end-to-end delay, which helps us in regulating the amount of traffic in the network. We also implement an association control scheme that utilizes available bandwidth as the design metric and enables end users to make intelligent access point selection decision. We demonstrate the advantages of these approaches in terms of achieving better network performance, and enabling effective resource control. Lastly, we consider the problem of fault diagnosis in wireless networks. We design and implement a novel framework wherein unique signatures are maintained for different network faults. These signatures help us identify the occurrence of a particular fault in the network, and also enable us to distinguish them from legitimate network events.

Available in PDF, EPUB and Kindle. Book excerpt: Overview and Goals Wireless communication technologies are undergoing rapid advancements. The last few years have experienced a steep growth in research in the area of wireless mesh networks (WMNs). The attractiveness of WMNs, in general, is attributed to their characteristics such as the ability to dynamically self-organize and self-con?gure, coupled with the ability to maintain mesh connectivity leading, in effect, to low set-up/installation costs, simpler maintenance tasks, and service coverage with high reliability and fault-tolerance. WMNs also support their integration with existing wireless networks such as cellular networks, WLANs, wireless-?delity (Wi-Fi), and worldwide interoperability of microwave access (WiMAX). WMNs have found u- ful applications in a broad range of domains such as broadband home networking, commercial/business networking, and community networking – particularly attr- tive in offering broadband wireless access with low initial installation and set-up costs. Even though WMNs have emerged to be attractive and they hold great promises for our future, there are several challenges that need to be addressed. Some of the wellknownchallenges areattributedtoissuesrelatingtoscalability(signi?cantdrop in throughput with the increase in the number of nodes), multicasting, offering qu- ity of service guarantees, energy ef?ciency, and security.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, with the dramatic improvement in Wireless Networks the need for Quality of Service in all types of the networks has been increased as well as increasing demand of new multimedia services has pushed the research on scalable video and audio streaming over wireless networks towards heterogeneous receivers in both industry and academia. The main idea behind improvement of Quality of Service is to find various methods to improve QoS, which can be used by different users according to their need. We choose Wireless Mesh Network the IEEE standard 802.11s as our principal network for experiments. We make possible that end-users can selectively decode the bit-stream according to their computational power, visualization capability, available bandwidth and network conditions to get the best quality multimedia. However, robust streaming of video over wireless networks has to deal many challenges including bit-errors, packet-losses, burst-packet-losses and many more due to varying nature of wireless networks. The effect of high error rates can be devastating for streaming of scalable video, which uses motion-compensated prediction. Many approaches dealing with the error recovery have been proposed in literature such as error resilience, error concealment, forward error correction (FEC), automatic repeat request (ARQ), path diversity and many more. However, none of these approaches can fulfill all quality criteria by it. A scalable bit-stream of video consists of a base layer and one or more enhancement layers. The base layer represents the most important part of video data while the enhancement layers serve only to refine the base layer quality hence making the performance of streaming applications that employ layered representation sensitive to losses of base layer packets. Therefore, the base layer needs to be protected more strongly as compare to enhancement layers. However, assigning unequal error protection to scalable video is more complex than non-scalable video due to layer structure. In this thesis, techniques for robust scalable multimedia streaming over wireless networks towards heterogeneous receivers are proposed. The proposed schemes are simulated and as well as implemented on the real platform developed by us with collaboration of my home University, University of Balochistan, Pakistan. After various experiments on simulator and test-bed, our results show that our proposed approaches can react to varying channel conditions with less degradation in video quality as compare to other existing approaches.

Download or read book Towards Efficient and Fair Resources Management in Wireless Mesh Networks written by Ali El Masri and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main purpose of Wireless Mesh Networks (WMNs) is to provide a communication backbone for a high number of end-users, thus WMNs have to support heavy traffic load. In this thesis, we intend to maximize utilization and achieve fair allocation of the bandwidth resources in WMNs. We consider two WMN environments: WMN using the IEEE 802.11 MAC standard, which is characterized by its cheap devices and widespread deployment, and WMN using directional antennas, which are emerged as an attractive technology to enhance the spatial reusability in wireless networks. For WMM based on IEEE 802.11, we design NICC, a congestion control scheme that recognizes congestion as neighborhood-related problem, and not a link-based one. Indeed, complex interference among neighboring nodes is the main starvation cause in WMNs. Therefore, NICC handles congestion using mutual cooperation within a wireless neighborhood. NICC makes use of some underexploited fields in the IEEE 802.11frame header in order to provide an implicit multi-bit congestion feedback, and thus ensure accurate rate control without generating overhead, making efficient use of bandwidth. For WMN with directional antennas, we design FreeDMAC, a TDMA-based MAC scheme with contention-free scheduling. FreeDMAC guarantees that each node is aware of all ongoing transmissions in its neighborhood, and thus avoids directional-related problems such as deafness, making efficient use of bandwidth. Moreover, FreeDMAC presents a link-slot assignment that provides two levels of fairness: Per-link and per-flow fairness.
