An Optimal Scheduling Algorithm for Maximizing Throughput in WiMAX Mesh Networks
Abstract— The WiMAX mesh network (WMN) architecture is defined in the IEEE 802.16 standard for increasing network coverage and improving communication performance. In the past few years, several greedy or heuristic algorithms have been proposed to cope with the scheduling problem in WMNs. However, their performance highly depends on the network topology and bandwidth requests, and they do not achieve optimal performance in all cases. Proposes an optimal scheduling algorithm called the scheduling algorithm with dynamic programming approach (SADP), which exploits the opportunities of spatial reuse and maximizes the network throughput based on the network topology and the uplink bandwidth requests of each subscriber station. In addition, a heuristic scheduling algorithm HSA < Final Year Projects 2016 > is proposed to reduce the computing complexity. The performance results were approximate to the optimal results.
