Ad Hoc网络中的节点是由电池供电,整个网络是一个能量受限系统,如何节省节点的能量,尽可能延长网络的可操控时间逐渐成为衡量路由协议性能的重要指标.基于移动节点能量的不同级别,采取不同的转发策略,提出了一种基于能量感知的Ad Hoc网络路由协议——EARP.并与AODV协议进行了性能比较,仿真结果显示,EARP具有较低的能耗,较长的网络存活时间.
The Ad Hoc networks is an energy constrained system with the portable devices,it is a very important metric to evaluate the protocols whether which have a longer network lifetime or not.Based on the mobile node energy level and using the different forward tactics,we present an energy aware routing protocol,EARP.By simulating the two routing protocols AODV and EARP,we find EARP has lower energy consumption and longer network lifetime than AODV.
