WiMAX Mesh网络中一种集中式QoS调度算法
Centralized scheduling algorithm based on QoS in WiMAX Mesh network
摘要
Abstract
This paper analyzed the pros and cons of existing scheduling algorithms,and proposed a new centralized scheduling method based on grouping data in WiMAX Mesh network. According to the standard QoS definition in Mesh mode, the algorithm grouped the various business data stream by its priority and calculated the node weight in order to guarantee the fairness of nodes between business data stream of the same category. The simulation results show that the proposed algorithm performs better both in the latency of grouping business and the network throughput compared with other two typical centralized scheduling algorithms: HRF and LTD, and can achieve the QoS standard for different business data stream.关键词
