摘要： 针对如何在Ad hoc网络中选择多路径的问题，对备份源路由协议进行改进。在路由发现过程中综合考虑网络的链路服务时间和传输延迟，引入一个因子，用于选择一条主路径，采用改进的成本函数选出一条与主路径相关性较小的路径作为备份路径，用主路径和备份路径组成的路由对发送数据包。实验结果表明，改进后的协议能减少路由发现次数，提高路由可靠性和网络性能。

Abstract: According to the question how to choose multipath routes in Ad hoc networks, this paper improves Backup Source Routing(BSR) protocol. It considers link service time and transmission delay of the network in routing discovery, chooses a primary route according to a factor and a backup route which has little correlation with the primary route according to the improved cost function. It transmits data packet by using the route pairs with the primary route and the backup route. Experimental results demonstrate that the improved protocol can decrease the count of routing discovery and improve the routing reliability and network performance.
