Abstract: The paper proposes a multipath routing protocol(multipath routing protocol based on a hybrid criterion to choose routing, HC-MRP) based on DSDV in Ad Hoc networks. By the cross-layer technique, it proposes a hybrid criterion based on the shortest path criterion and the best channel state criterion, and establishes a neighbor node structure by which the multi-path mode can be expanded. The multi-path dividual transmission is employed as the transmission mode of paths. The simulation shows that by the mode of multi-path dividual transmission, the proposed protocol improves the throughput with a little price of the performance of delivery.

摘要： 在Ad Hoc无线网络环境下，提出了一种基于DSDV的多径路由协议HC-MRP。HC-MRP路由协议利用跨层的思想，提出了一种基于最短路径准则和最佳信道状态准则的混和路径选择准则，并通过建立一个邻居节点表结构，实现了多径扩展，多径的传输模式采用多径独立传输模式。仿真表明，HC-MRP协议以少量的递交率性能为代价，提高了整个网络的吞吐量。
