Aiming at problem of narrow and complex communication environment in mine tunnel,a redundant node deployment strategy for wireless sensor networks( WSNs) based on isosceles triangle is proposed,which is very simple and easy to implement. It can ensure the tunnel is at least 3-covered which meets requirements of localization of mobile nodes; at the same time,the redundant deployment strategy of node can maintain stability of data transmission when individual nodes are failure. Test results show that the deployment strategy can ensure network has low packet loss,and realize localization of mobile nodes without increasing too much monitoring nodes.
