移动Adhoc网络的分簇后择路由协议

为了充分利用无线通信信道的广播特性,提出了一种分簇的移动Ad hoc网络后择路由(opportunistic routing)协议.该协议在转发数据包时,首先向相邻节点广播该数据包,然后在正确接收到数据包的节点中选择一个合适的节点转发.采用这种方法可以克服无线信道质量不稳定的缺点,同时利用了传统的路由协议无法利用的长距离不稳定链路.仿真实验表明,这种路由协议可以大大减少数据包在网络中的转发次数,提高了整个网络的吞吐量.

Clustered opportunistic routing protocol for mobile Ad hoc networks

To efficiently exploit the inherent characteristics of radio channels,a clustered opportunistic routing protocol(CORP) was proposed.CORP forwards a data packet by broadcasting it first,then selects the most appropriate node among those that receive this packet to forward it further.As a result,CORP can use long and unreliable radio links which would not be used by traditional protocols.The experiment results show that the proposed protocol presents significant performance improvements,especially in average transmission numbers and network throughput.
