A New Approach for Scheduling of Wireless Mesh Networks

ABSTRACT Wireless mesh networks (WMN) is a technology which provides wireless broadband connectivity to the Internet. This network, by applying only one hot spot and several transient access points, an Internet Service Provider can extend its coverage and serve a large number of clients using a single broadband connection. However, if the medium access protocol is poorly designed or inadequate, it can lead to severe unfairness and low bandwidth utilization. This paper presents a scheduling of wireless mesh networks in WMNs. First, existing scheduling solutions are discussed and classified based on technique and implementation framework. Then, the novel proposed scheme is discussed in detail. This technique is a multiple gateway fair scheduling scheme. This scheme consists of distributed routing and requirement tables and a propagation algorithm for scheduling at the gateways. Simulation results confirm that fair scheduling has better performance than the scheme without fair scheduling and that multiple gateways are beneficial
