A Fair Rate-Balance link Scheduling in WiMAX Mesh network

Abstract

In order to ensure the fairness of links and network stability, this paper analyzes the link scheduling model in WiMAX Mesh network and proposes a Fair Rate-Balance link Scheduling scheme (FRBS). FRBS calculates the scheduling parameter under stability constraint making the arrival data rate of the link equal to outgoing rate. At the grant step, FRBS assigns bandwidth using a max-min fair Round Robin algorithm for link fairness. Simulation results show that FRBS has much better performance than the greedy scheduling in both light load and heavy load network.
