Abstract: Considering the difference between single-interface and multi-interface，the protocol of single-interface can not suit
for the multi-interface completely.To this problem，this paper proposes a new route strategy，which considers the link diversity
cost and node load rate.In order to choose a better link and improve the throughput of network，a new route metric is
proposed in new route strategy.Simulation experiments show that compared with AODV，the new metric is valid.In the same
conditions，the packet delivery fraction and the throughput are enhanced.

摘要： 在分析单接口和多接口路由算法差别的基础上，发现支持单接口的路由算法不能很好地适应多接口的情况。针对这个问题，综合考虑了链路多样性成本、节点负载度，提出一种新的路由策略和路由判据。仿真结果表明，采用新的路由判据后，与标准AODV相比，数据分组的到达率和网络的吞吐量得到了很大改善。
