| 摘 要： | 针对树状拓扑的大规模传感器网络中存在的节点能量和传输效率问题,提出了一种基于大规模网络分解和协调的无线传感器网络(WSNs)MAC协议。该协议在路由信息的基础上对网络进行再一次分解,并采用了与之相适应的节点接入算法。实验结果表明:该协议总体能耗低、传达率高且具有一定的自适应性,同时网络时延并没有因为分层而增加。该协议对大规模无线传感器网络有良好的适用性。

| Abstract: | The problem of power and transmission efficiency of Tree-topology large-scale wireless sensor networks(WSNs) is researched and a new MAC protocol based on decomposition and coordination of large-scale network is proposed.The MAC protocol decomposed the network again according to the route information,and a new access algorithm that is adapting it is introduced to the sensor nodes.The experimental results show that the performance of the MAC protocol has lower power consumption and better delivery rate without any addition of delay in evidence.And the protocol can adaptive the large-scale WSNs well. |
