摘要
分析了功率控制和AODV协议的工作原理。针对无线传感器网络中的"热门"节点过早死亡及能量空洞的问题,提出了一种跨层功率自适应的节能AODV路由协议。采用RREQ协议帧的扩展,通过节点剩余能量对RREQ协议帧进行选择性转发,优化了RREQ广播过程。NS2仿真结论表明,在保证较低延时和较高吞吐率的同时,该方案有效地降低了网络传输的能量消耗,达到延长网络的生存周期的目的。
In order to eliminate premature dead hotspots and energy holes in the wireless sensor networks, it designs a AODV routing protocol with self-adaptability across multi-tiers and energy balance was designed to optimizes the RREQ broadcast process with an extension of RREQ protocol and selectively routing the frames of RREQ protocol by residual power in the node. The result of NS2 simulation indicates that this solution dramatically cuts down the energy consumption during the network transmission to extend the network life circle, while still ensures the network with low latency and high throughput.
