一种新的基于位置和电池能量感知的路由协议

A Novel Location-Based and Energy-Aware Routing Protocol

能量消耗问题是Ad Hoc网络中研究的热点问题之一。针对基于位置的路由协议没有考虑节点剩余能量的问题,提出了一种结合位置信息和剩余能量的路由协议。该协议主要目的是均衡节点能量的消耗,延长网络的生存时间。本协议是在贪婪无状态周边路由协议(G reedy Perim eter State-less Routing,GPSR)基础上进行改进的,并通过NS仿真对比这两种协议。仿真结果表明,该路由协议在不降低成功传送率的情况下,能够延长网络的生存时间,提高系统的吞吐量。

Energy is crucial to Ad Hoc network because most of nodes must rely on their limited battery supply. In many location-based routing protocols, residual energy of node is not considered. In this paper, we propose a new routing protocol which combines location information and residual energy. The object of our routing protocol is to balance consumption of energy of nodes and prolong the surviving time of network. We implement our routing protocol based on greedy perimeter stateless routing （GPSR）. We evaluate our proposed routing protocol and GPSR through NS simulator. The results show that our routing protocol can prolong the surviving time and improve the throughput.
