Impacts of refresh interval parameters on M-OLSR performance for Wireless Mesh Networks
Singapore（2009）
摘要
Modified optimized link state routing (M-OLSR) has been developed for adaptability in wireless mesh networking (WMNs) scenarios and exhibits a much better scalability of traffic load and mobility in sparse and dense network. The protocol uses some refresh timers for periodic updates of link information and for subsequent topology maintenance. In this paper, we investigate the impact of configuring refresh timer interval on protocol's performance under various networking scenarios. Simulation results demonstrate that, HELLO message timer interval has bigger impact than topology control (TC) message timer on M-OLSR performance. And, as the network mobility increases, the impact of configuring refresh timer interval has greater effect than a relatively stable network.
