Ad Hoc网络中多径路由协议的研究

Research on Multipath Routing Protocol in Ad Hoc Networks

在对Ad Hoc网络中多径路由协议研究的现状和成果进行总结的基础上,提出了一种应用于Ad Hoc网络的基于DSDV的多径路由协议MPDSDV:准备通信时,源节点首先向邻居节点发送路由探测包,邻居节点向源节点反馈路由信息包,从而获得从源节点到目的节点的多条路由信息。对MPDSDV进行仿真,结果表明:在节点移动速度较快,网络负载不是很大的情况,MPDSDV较大地提高了数据包的投递率,降低了丢包率,从而有效地改善了网络的性能。

Based on the summary of the curren situation and production of the research of Multipath Routing Protocol in Ad Hoc Networks, proposes a novel multipath routing protocol based on DSDV for Ad Hoc networks, Muhipath Destination Sequenced Distance-Vector （MPDS- DV）： before communication, source node first sends routing detect packets to its neighbors, after that the neighboring nodes respond their feedback routing information packets, based on this procedure the multipath routing information from source to destination can be obtained. The simulation results show that MPDSDV increases the packet delivery ratio of data packets and reduces the packet drop ratio in the situation that nodes move comparatively fast and networks load is not very large. As a result, MPDSDV efficiently improves the network performance.
