The invention relates to a method for remodeling a wireless remaining sensor network in a complex environment. The method comprises the following steps: firstly, determining a paralysis region and selecting a node closest to the paralysis region as a final target node; and after a mobile carrier on which a plurality of sensor nodes are mounted realizes autonomous routing in the network to reach the final target node by constantly positioning and correcting the direction of forward motion, determining a direction of entering the paralysis region by use of an RSSI distance measurement technology and a mathematical model, and remodeling the wireless sensor network according to a chained network establishment principle to realize the basic functions of an original network. The method is used for solving the problem of node connection failure due to the paralysis of few nodes and the problems of resource waste and the like due to blind scattering network supplementation in the wireless sensor network in the complex environment.
