| 摘 要： | 在分析LEACH路由协议算法的缺点的基础上,提出了一种用于无线传感器网络的基于流量自适应的TDMA分簇算法协议.该协议根据当前节点数据流量的变化,自适应地调整该节点在其簇内通信的时隙长度,减少节点空闲时消耗的能量和节点从睡眠到活跃状态来回切换的能量.仿真实验结果表明,与LEACH协议簇内时隙分配算法相比,运用这种新的时隙分配算法,可以节省节点的能量,提高网络的生存时间,改善网络性能.

| Abstract: | The chief drawbacks of the LEACH protocol are analyzed and a traffic-adaptive clustering protocol based on TDMA for wireless sensor networks is proposed in this paper. This protocol can adjust the slot length of the wireless sensor nodes adaptively according to the traffic changement on the node, so the idle energy consumption and the consumed energy on the state change of the nodes can be reduced. Simulation results show that the traffic-adaptive clustering protocol can reduce the energy consuming under different traffic loads and get improvement on the life of the network compared with the LEACH protocol. |
