| 摘 要： | 针对S-MAC协议节点能耗均衡能力的不足，提出一种基于网络能耗均衡的跨层优化协议(BS-MAC)。在该机制中，增加变量TS，用来记录该节点成为虚拟簇边界节点的次数，通过与邻居节点比较TS的大小进行自适应睡眠/侦听。在路由层成簇算法中加入参数TS，跨层调节节点能耗的均衡。仿真数据显示，BS-MAC在能耗和延迟方面较S-MAC没有大的变化，但能够提高网络节点能耗的均衡性，降低节点死亡率，延长网络生存周期。

| Abstract: | For the fault of S-MAC protocol in energy-consume unbalance between nodes,a cross-layer optimization MAC protocol based on energy-consume balance(BS-MAC) is proposed.The new mechanism adds the new variable TS to record the number of times that the node becomes virtue clusters’ boundary.Nodes sleep/listen adaptively through comparing TS with their neighbor nodes.BS-MAC adjusts the balance of energy-consume cross-layer with the clustering algorithm which adds TS.Numerical analysis shows that BS-MAC not only increases the balance of the nodes’ energy consumption,reduces the nodes’ mortality and extends the network life time,but also keeps the same energy-consume and delay with the S-MAC. |
