摘要: Ad hoc网络节点能量受限的路由协议的研究是目前的一个热点,IETF的MANET小组提出的几种经典的路由协议,属于最短路由,即最小跳数路由,没有考虑能量因素。由于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成为衡量路由协议性能的重要指标。目前针对这几种路由协议基于节点能量约束的评估很少。基于移动模型,该文以能量消耗程度为指标,对Ad hoc 4种典型的路由协议在不同的运动场景下进行了比较系统的仿真研究,得出了一些有益的结论,为进一步研究基于能耗的Ad hoc网络路由协议提供一些参考。

Abstract: The study of energy constrained routing protocols in Ad hoc networks is attracting more attention currently. Typical routing protocols presented by the MANET of IETF are the shortest routing, that is, it is with the least hops but without considering saving energy. Because the Ad hoc networks is an energy constrained system with portable devices, whether network lifetime can be extended or not becomes very important metric to evaluate the protocols. There are a few evaluations of the energy constrained routing protocols. Based on the mobility model, this paper analyzes the performances of four Ad hoc routing protocols with metrics of energy consumption and draws some instructive conclusions as reference for the study of Ad hoc routing protocol based on energy consumption.
