能量采集无线Mesh网路由协议研究

无线Mesh网以其容量大、速率高、范围广、组网灵活,成为未来宽带接入网的一个重要方案。能量问题是制约无线Mesh网可靠性和健壮性的因素之一。为了消除该制约因素,创造性地将能量采集(energy harvesting)技术引入到无线Mesh网中,使无线路由器可以从环境中收获或采集能量,具有自我补充能量的能力。还就无线路由节点能量模型,进行基于能量收集的分簇路由协议的分析仿真,将能量采集技术与LEACH协议和DEEC协议相结合,并通过仿真,分析比对在引入能量采集技术后两种路由协议的性能。仿真结果表明结合了能量采集技术的DEEC协议在延长网络寿命、提高数据传输量方面表现最优。

Research on Routing Protocol in Wireless Mesh Networks with Energy Harvesting

Thanks to its large capacity, high speed, wide range and flexibility, Wireless Mesh Networks becomes an important schemes of future wideband access networks. The energy problem is one of the constraining factors for the reliability and robust of Wireless Mesh Networks. In order to diminish this factor, this paper creatively introduce Energy Harvesting technology into Wireless Mesh Networks, making the wireless routers can collect or harvest energy from the environment, namely, have the capacity of self-energization. With regard to wireless router energy model, this paper also simulate the clustered routing protocols with Energy Harvesting. We combine Energy Harvesting with LEACH protocol and DEEC protocol, and analyze the performances of these combinations through simulations. The simulation results show that the DEEC protocol with Energy Harvesting performs best in prolonging the network lifetime and enhancing the data bulk.
