Abstract: In this paper，the energy consumption of AODV and OLSR Hybrid Routing（AOHR） protocol is analyzed.In AOHR，each node maintains topology information of a zone with radius no larger than an appointed value.By the proactive property of OLSR，when a node communicates with another node within its zone，packets can be transmitted directly.By the reactive property of AODV，when a node communicates with another node beyond its zone，a routing request procedure will be invoked.In addition，AOHR utilizes MPR（Multipoint Relay） to reduce the overhead of routing requests.AOHR also supports a method of dynamic zone radius maintenance to improve its performance.Analysis and simulation results show that AOHR has the longest lifetime and most uniform energy consumption in these three types of routing protocols.

摘要： 对AODV与OLSR混合路由协议（AOHR）的能耗进行了分析。在AOHR中，每个节点维护指定跳数内的节点和路由信息，在和该区域内的节点通信时可以利用OLSR协议的先验特性直接获得路由信息；在和该区域外的节点通信时可以利用AODV协议的后验特性进行动态路由查询和建立。AOHR协议还利用了OLSR协议提供的多点中继转发MPR（Multipoint Relay）来减少AODV广播包的网络开销。此外，AOHR协议还可以采用区域半径动态调整的策略来提高协议的普适性。针对AOHR协议的这一特点，对区域半径动态维护的AOHR协议与AODV和OLSR协议在能耗方面的差异进行了理论和仿真分析。结果表明AOHR协议具有比AODV和OLSR协议更长的生存期，并且每个节点的能耗更加平均。
