【摘要】 提出一种具有负载平衡能力的ad hoc网络路由协议(LBHR)。LBHR根据不同的网络拓扑结构变化速度,在按需路由和表驱动路由之间进行自然平滑的切换。LBHR采用以下措施来实现负载平衡:在一对源节点和目的节点间,使用多条路径来发送分组;过载的节点不参与路由发现过程。仿真结果表明,LBHR在分组投递率、端到端延时等方面具有较好的性能。更多还原

【Abstract】 A hybrid routing protocol for ad hoc network,which is capable of load balance,is proposed in this article.In the hybrid routing strategy,the rate of topological change provides a natural mechanism for switching dynamically between table-driven and on-demand routing.LBHR takes the following measures to realize load balance: multiple paths are used to deliver packets between a pair of source-destination nodes;the overloaded node will not take part in the procedure of route discovery.The simulation results indicate that the protocol has good performances in terms of packet delivery ratio and average end to end delay.更多还原
