摘要
为解决AdHoc网络的DSR路由协议在通信过程中存在拥塞问题,提出了改进DSR路由协议的思想,即联合"最短路径"和节点发送接收数据包时的"传输状态"来避免拥塞。仿真结果表明,改进后的路由协议有效地减少了发生拥塞的几率,从而提高了无线多跳AdHoc网络环境下Web通信的性能。
In order to solve the problem of traffic congestion that always occurs in multi-hop ad hoc networks, a new algorithm for the routing selection was proposed in this paper, i.e. the improved DSR routing -- DSRSL, in consideration of both the＂ shortest-path＂ and ＂ transmission status＂ of packet delivery from the source to the destination for congestion avoidance. Our simulation results show that DSRSL can reduce the congestion probability effectively, thereby improve the Web traffic performance in multi-hop ad hoc networks significantly.
