A multi-path routing protocol based on a hybrid criterion of choice
一种混合路径选择准则下的多径路由算法

A multi-path routing protocol based on DSDV(Destination Sequenced Distance-Vector) in Ad hoc networks was proposed.A new neighbor node structure like routing table was established by which the multi-path mode can be expanded.The proposed protocol chooses routing by a hybrid criterion which is based on the shortest path criterion and the best channel state criterion.The hybrid criterion makes use of the information at physical layer related to cross-layer technique.The multi-path dividual transmission was employed as the transmission mode of paths.The simulation shows that,by the mode of multi-path dividual transmission,the proposed protocol greatly improves the throughput of the whole network at the expense of little delivery performance,and increases the utilization ratio of network resources.
