摘要
Ad Hoc网络具有移动性和链路高失效率,多径路由的提出就是为了减少由于链路失效造成的路由开销增加和分组投递率的减少。现有的多径路由追求链路的独立性大多选择不相交多径,但不相交多径在主路径失效后提供的备用路径不一定最优。在AODV协议的基础上提出了一种相交多径的方案(M_AOMDV)。仿真结果表明M_AOMDV降低了时延和开销,提高了网络性能。
Because of the node mobility and the frequent link break in Ad hoc networks, multipath routing is advanced to reduce the routing overhead and to improve the delivery ratio. Most muhipath rou- ting is disjoint routing and links in it are independent. However, disjoint routing sometimes can not offer optimistic backup path. A joint multipath routing protocol （M_AOMDV） based on AODV is proposed. Through simulation, the protocol reduces delay and overload, and improves the performance of networks.
