Abstract: In ad hoc networks，traditional single path routing does not have a big breakthrough for the performance of ad hoc network.Therefore，the design of efficient and stable multipath routing has been the most focused area.This paper proposes a new multipath routing algorithm.During the route discovery，the algorithm uses a new multipath forwarding strategy.Based on similarity factor，the algorithm computes Hamming distance and accordingly selects similar stable disjoint multi-route，which will further enhance the performance of the routing algorithm.Simulation results show that compared with classical multipath routing，the proposed algorithm is an efficient routing.

摘要： 传统的单路径路由使自组网路由性能一直不能获得太大的突破。因此，设计有效的和稳定的多路径路由成为最受关注的问题。为此提出了一种新的多路径路由算法，其在路由发现阶段使用了一种新的多路径转发策略。在基于稳定性因子的基础上，该算法计算路径间海明距离并据此选择多条相似的稳定不相交多路由，从而进一步提高该路由算法的性能。模拟结果显示，与经典的多路径路由相比较，该算法是一个有效的多路径自组网路由算法。
