This book was released on 2014 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: The design and the management of Wireless Mesh Networks (WMNs) are currently associated with the most active research area within the current wireless networking paradigms. WMNs inherit features from existing wireless networking technologies such as WLANs, mobile ad hoc networks. Because WMNs are easy to deploy and with low power consumption, there is a phenomenal growing interest in seeing WMNs as the next wireless backhaul networks, and an alternative to the existing wired infrastructure. The earliest development of WMNs had begun with single-channel single-radio mesh networks. This technology then evolved towards multi-channel single-radio mesh networks, and then to multi-channel multi-radio mesh networks. WMNs operate in North America on IEEE 802.11 2.4 GHz spectrum, which provides up to 11 channels. Despite the availability of 11 channels, only 3 (1, 6, 11) orthogonal channels can be used concurrently. The efficiency of multi-channel multi-radio wireless mesh networks can be improved with the increase of the number of channels used concurrently and of multiple radios. In this study, we investigate how to design a scalable channel assignment and a scheduling algorithm, which both exploit partially overlapping channels in order to increase the throughput in comparison with the one that can be obtained only using three orthogonal channels. In order to accurately take into account the radio interferences, we use the physical interference model to estimate the interferences among wireless links. We then introduce the definition of transmission configurations, which are sets of links, which can transmit concurrently. These links can be assigned with channels of overlapping or orthogonal in nature. We then design a TDMA based scheduling allowing a transmission configuration to transmit concurrently in a time slot. Finally, we evaluate all our algorithms through extensive simulations. Our numerical experiments show that we can gain up to 25% for the throughput by appropriately managing all the available channels.

Download or read book Efficient Use of Partially Overlapping Channels in WMNs written by Mahdi Negahishirazin and published by . This book was released on 2015 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been growing interest in using Wireless Mesh Networks (WMNs) because of their advantages such as easier to scale up and self-organization. We instigate whether increasing the number of available channels through the use of Partially Overlapping Channels (POCs) is always useful for improving the Quality of Service (QoS) of WMNs namely the throughput or delay. For the purpose of this thesis, we design a set of algorithms for: i) Channel assignment; ii) Transmission Configurations (TCs) which is a set of links with the ability of sending data simultaneously; iii) power control; and iv) delivery of packets to their destination in order to take advantage of POCs in WMNs. We evaluate our proposed algorithms by a comprehensive set of numerical experiments. Numerical experiments indicate that using POCs leads not only to increase throughput of networks, but also it can decrease delay of packet delivery.

Available in PDF, EPUB and Kindle. Book excerpt: Mesh networks is a class of wireless networks consisting of a set of backbone nodes and some client nodes. In this work, we look at the problems of routing, scheduling and power control in such networks, with the ultimate goal of increasing the throughput while satisfying all the traffic requirements. Increasing the throughput of the network implies the ability to send more data between as many source and destination nodes as possible, in shorter periods of time. To achieve this, we need intelligent scheduling schemes that take advantage of the spatial reuse that is possible. We outline two heuristic scheduling algorithms that look at various ways of ordering the links and choosing the ones that might reduce the schedule length, which is a measure of the throughput of the network. The simpler algorithm works at the candidate node level for each slot, while the more complex independent sets based algorithm works with individual links. Different options have been outlined for choosing the first and subsequent links of every slot in the schedule. This includes the interference score of the link, the magnitude of traffic requirement, the specific interfering links, etc. We also study in detail how the links in the network affect the schedule length. When certain links are scheduled, the spatial reuse factor is reduced to zero, implying that no other links can be active at the same time as these links. Hence it is of interest to us to study more about these "loner" links as they add to the schedule length. We characterize these links for topologies in square and circular areas. Using simple geometric arguments, we show that links of length 0.579k and 0.485d in a square area of side k and circular area of diameter d respectively, will always be loners. We also outline a method to analytically find the number of loner links in a given network. This number gives a lower bound on the schedule length. With the understanding gained from the study of scheduling heuristics, we p.
