摘要:
无线传感器网络(wireless sensor network,WSN)中如何延长路由节点的生命期和保证网络正常运行非常重要.以WSN主控芯片CC2430为硬件基础,建立了在ZigBee协议下固定节点的链状网络路由模型,提出了一种网络自愈的方法,即为每跳路由节点配备一个备用路由节点,利用高斯算法对各路由节点接收信号强度(received signal strength indication, RSSI) 值进行检测,依据检测的RSSI值判定电池的供电情况,进而决定是否启动处于睡眠的备用路由代替当前路由承担相应的工作.实验结果表明,在没有环境因素的情况下,可以较好地实现自愈功能.
Abstract:
In wireless sensor network (WSN),it′s of vital importance to prolong the lifetime of the routing node and to ensure the network running properly.In this paper,a chain network routing model of ZigBee protocol of the fixed nodes is built and a method of selfhealing is put forward on the base of CC2430 of the WSN main control chip.The method is firstly to equip every routing node with an alternate routing node.Then,use the Gauss Algorithm to detect the received signal strength indication (RSSI) of the routing node in order to determine the battery power supply state,and then to decide whether to activate the dormant alternate routing node replacing the current routing node to work or not .As the experimental results show,if the environmental factors are ignored,the selfhealing function can be achieved.
