摘　　要：针对目前LOAD路由存在的个别节点能量消耗过快导致整个网络瘫痪以及路由请求频繁的问题,提出改进OLOAD路由协议,加入能量模型作为路由代价之一并且设计备用路由,当活跃路由失效时,更新备用路由为活跃路由。经过NS2平台对O-LOAD路由进行仿真,结果证明O-LOAD路由具备高数据投递率和低路由开销的优点,同时有效延长了网络的生存时间。In view of the current energy consuming too fast in some individuaI nodes and the routing requesting too fre-quentIy in LOAD routing,this paper presents the improvement of O-LOAD routing protocoI.Energy modeI added as one of the routing cost,design aIternate route,when the active route faiIs,update aIternate route for the active route.NS2 pIatform for O-LOAD routing simuIation resuIts prove O-LOAD routing with the advantages of high data rate and Iow routing Ioad,whiIe effectiveIy extending the Iifetime of the network.
