摘要
针对无线传感器网络因电池供电而存在能量受限的问题,设计了一种低功耗无线传感器网络节点和一种分层单向路由算法。无线传感器网络节点由ARM低功耗微处理器STM32F103C6T6和SI4421射频无线收发芯片构成。分层单向路由将传感器节点与基站节点根据位置远近不同划分到不同的层,通过对无线传感器网络节点自身功率控制和无线数据选择最优路径降低节点功耗,延长无线传感器网络整体寿命。能耗仿真与组网试验表明,该设计数据传输可靠,且效率低。
The nodes of WSN are battery-powered, so the problem of limited energy exists. Aiming at this issue, the low power node of WSN, and the hierarchical unidirectional route algorithm have been designed. The node of WSN is composed of ARM low power microprocessor STM32F103C6T6 and the RF wireless transceiver SI4421. The sensor nodes and the base station nodes are assigned to different layer by the hierarchical unidirectional route according to different locations near or far. The power consumption of the node is reduced through controlling the power of the node itself, and selecting optimal path for wireless data transmission, and the overall life cycle of the network is extended, The simulation of energy consumption and networking test indicate that reliable data transmission can be conducted by this design scheme under lower power consumption.
