摘　　要：Adhoc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Adhoc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。但是,目前针对这几种路由协议基于节点能量约束的评估很少。文章基于节点能量的约束,以能量消耗程度、节点终止情况和连能性为指标,对AdHoc四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,得出了与相关文献不一致的结论;基于我们的仿真结果,该文认为基于能耗研究Adhoc网络路由协议应以节点能耗的平衡性而不仅仅是能耗量的多少来考虑问题。The Study of Energy Constrained Routing Protocols in Ad Hoc Networks is attracting more attention currently.The typical routing protocols presented by the MANET of IETF are shortest routing,that is,the least hops and not consider the energy saving problem.Because 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.However,there is very little evaluation of the energy constrained routing protocols.Based on the node energy constrained,this paper analyse the relative performance of four Ad hoc routing protocols with the metrics of energy consumption,node termination and connectivity and draw the inconsistent conclusion.Furthermore,based on our simulation results,this paper presents that the study on Ad Hoe routing algorithms supporting the energy aware not only takes into account the quantity of energy consumption but also the balance of it.
