多信道无线传感器网络节点传输调度方法

Scheduling method for multichannel wireless sensor network node transmission

针对生成树结构的无线传感器网络功耗过高的问题,提出了一种多信道无线传感器网络节点传输调度方法。该方法可以对入口数据进行聚合,并仅向出口发送一个聚合数据包,将给定路由拓扑的无线传感器网络调度问题转化为二元线性规划问题加以合理解决。仿真结果表明,该方法与现行调度方法相比具有显著的优势。

To solve the problem of high power consumption in spanning tree structure of wireless sensor networks,a node transmission scheduling method for multi-channel wireless sensor networks is proposed.This method can aggregate the entry data and send only one aggregated packet to the exit.It can transform the scheduling problem of wireless sensor networks with given routing topology into a binary linear programming problem which can be solved reasonably.The simulation results show that this method has significant advantages over the existing scheduling methods.
