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.
