基于Jelger算法的多因素网关选择算法

摘要

针对移动自组织网络（mobile Ad hoc network，MANET）与Internet互联时的网关选择问题，提出一种基于Jelger算法的多因素网关选择算法来进行网关选择和切换。该算法综合考虑跳数、网关效益、通信成本等约束对网关选择的影响，在此基础上构建目标函数，引入网关选择度量——网关可用度（GUD）来完成网关的选择和切换。仿真结果表明，该算法能够有效改善Jelger算法引起的网关频繁切换问题和负载不均衡问题，减少网关切换次数，降低了传输时延和网络负载，提高了网络性能。%According to the problem of gateway selection of mobile Ad hoc network and Internet， this paper put forward a multi-factors gateway selection algorithm based on Jelger algorithm.
