Wireless mesh networks (WMNs) have been widely deployed for various applications.In contrast to a pure ad hoc network, a WMN having an infrastructure formed by fixed access points (APs) can provide relatively reliable transmissions for forwarding data to and from mobile stations (MSs). The fixed infrastructure also provides chances for effectively supporting various services, better utilizing the radio resources, and improving other network performance. On the other hand, in a WMN with a large number of APs and MSs, maintaining the service fairness among the MSs located in different geographical areas and having different mobility patterns can be difficult.In this thesis, we study how to provide fair throughput for MSs in a WMN by joint channel time allocations and handoff management, where the channel time is allocated at two levels, one among the APs, and another among the MSs associated to the same AP.In the first part of the thesis, we assume that the channel time allocations at the AP level are given, and jointly consider the handoff management of the MSs and the channel time allocations at the MS level. An optimization problem is formulated based on long-term proportional fairness (PF), so that all the MSs in the entire WMN can receive fair average throughput, while the total throughput of the MSs is maximized. The optimum solution is based on the assumption of having global information iv about the channel conditions and mobility information of all the MSs, and cannot be easily implemented in a practical system. A heuristic scheme is then proposed, which allows each AP to allocate its channel time based on local information only, and the handoff decisions of the MSs are based on information exchanged between neighboring APs. Numerical results show that performance of the proposed heuristic scheme is very close to the optimum in terms of both fairness and throughput.In the second part of thesis, we consider that different APs can share the same frequency channel and should coordinate for their transmission time, so that neighboring APs sharing the same frequency channel do not transmit at the same time in order to avoid strong co-channel interference. We jointly study the channel time allocations

“…(2) DCA approaches and power control schemes [2], [4], [5], [17], [18], [19] are considered as the most efficient techniques to manage scarce resource available to the system. Many researches demonstrated that a remarkable improvement in terms of spectrum efficiency and network capacity could be gained via integrating two techniques together [19], [20], [26].…”

In a wireless mesh network (WMN) with a number of stationary wireless routers, the aggregate capacity can be increased when each router is equipped with multiple network interface cards (NICs) and each NIC within a router is assigned to a distinct orthogonal frequency channel. In this paper, given the logical topology of the network, we formulate the joint channel allocation, interface assignment, and media access control (MAC) problem as a cross-layer non-linear mixed-integer network utility maximization problem. An optimal joint design, based on exact binary linearization techniques, is proposed which leads to a global maximum. A near-optimal joint design, based on approximate dual decomposition techniques, is also proposed which is of more interest in terms of practical deployment. Performance evaluation is given through a number of numerical examples in terms of network utility maximization and aggregate network throughput.
