A Stable Mobile ad hoc Network Routing Algorithm with Gray Prediction

将灰色理论应用于自组织网络拓扑连接状态预测,提高反应式路由协议(DSR)的预应能力,避免路由信息震荡,减小不必要的网络开销,迅速发现失效链路,提高了路由信息的稳定性.仿真结果表明,改进后的基于灰色模型的稳定路由协议S-DSR具有更高的稳定性,组网效率更高.

Due to the highly dynamic topology and complicated network scenario, stability is a key factor in ad hoe routing protocol efficiency. In this paper, the gray theory is applied to topology state prediction in mobile wireless ad hoe network in order to improve the proactive ability of reactive routing protocol such as DSR. In the developed routing protocol, a number of factors are taken into account to avoid turbulence of routing information in network, minimize unnecessary routing overhead, rapidly find disabled links and improve stability of routing information. Simulation results show that the stable routing protocol S-DSR based on the gray prediction theory is considerably more stable and efficient than that of the original one.
