基于ZigBee的无线传感器网络的自愈功能
Self-healing Function Based on Wireless Sensor Networks of ZigBee
摘要
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.关键词
