摘　　要：为解决因无线Mesh网络不稳定所产生的信号干扰、报文丢失及高延时等问题,提出利用链路稳定性指数和熵函数来刻画节点的稳定性,设计一种基于节点稳定性的可靠路由方案(NSBR),有效降低了数据传输期间可能会影响网络稳定性的路由中断现象的概率,增加了网络稳定性,提升了网络性能.研究结果表明:NSBR在吞吐量、延时和报文丢失率等方面的性能都要优于已有的RLBDR、MIC和ETX等路由协议.In order to solve the problem of signal interference, packet loss and high latency caused by the instability of wireless mesh network, this paper used the link stability index and the entropy function to describe the stability of nodes. A reliable routing scheme based on node stability（NSBR） was proposed. NSBR can effectively reduce the probability of network routing disruption which may lead to an instability network during the data transmission. It can also improve the performance of network, and increase the stability of network. The simulation results show that the performance of NSBR is superior to the existing RLBDR, MIC and ETX routing protocol in terms of throughput, delay and packet loss rate.
