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.

Key words: Wireless Sensor Network(WSN), cross-layer optimization, energy-consume balance, life cycle, clustering routing, BS-MAC protocol
