摘要 自组网中区域路由协议主要由区域内路由和区域间路由组成。修正的区域路由算法利用节点位置信息,使得区域内的邻节点更新过程可以获得更有效的触发,从而减少了大量的不必要的广播报文开销。同时,根据节点密度调整了路径长度限制,使得区域间的路由查询和路由维护能够更快地收敛。仿真结果表明,修正后的区域路由算法与ZRP协议相比,在时延、吞吐量等方面有着较明显的性能提高。 Zone Routing Protocol in MANET consists of IntrAzone and. IntErzone routing.Modified ZRP （MZRP） effectively triggers the neighbor nodes＇ update process of IARP,in use of position information,accordingly the broadcast overhead has been decreased much.Also,MZRP modifies the limit of route length based on the node density,and results in rapider convergence during route query and maintenance in IERP.Simulation results show that,contrast to ZRP, modified scheme has better performance in the case of delay,throughput,etc.
