Abstract:According to the requirements of WSN positioning in chain roadway and the characteristics of node deployment,a K-coverage(K ≥ 3)control algorithm LKCC is proposed for chain wireless sensor networks. The simulation experiments show that LKCC algorithm can effectively extend the network life cycle through sleep mechanism. Compared with the classical K-coverage control algorithm CCP,the algorithm can guarantee K-coverage(K ≥ 3)of the chain network and the average number of nodes used in the same WSN network life cycle is reduced by 34.26%.
