摘要
主要讨论具有双通道的无线传感器网络的节能通信方案设计和仿真问题。先简述了单片无线收发芯片的技术特点。然后设计了汇交和测量节点的操作流程图。还讨论了通信过程关键参数选择问题,和估算了此类网络的能耗、数据传送速率等指标。提出的通信方案在保证正常数据交换的同时能大幅度地减少测量节点的能耗。
The design and simulation of low-power communication scheme for star wireless sensor network is described.This paper first briefs the technical features of wireless module for each node,then discusses the design of operation procedures for sink and measurement nodes,finally treats of the parameter selection and performance criteria of this network.The proposed communication scheme could effectively reduce the power consumption of measurement nodes while ensures the normal data exchange between the measurement nodes.
