Wireless Sensor Network is variously designed with many application fields, but any vicious attacker can easily damage the exposed nodes. Its node has the vulnerability. False reports can decrease the lifetime of a whole network as well as these reports delivered from the base station make the false alarms. For resolving these problems, many techniques are proposed. The proposed statistical en-route filtering (SEF), path selection method (PSM), and path renewal method (PRM) presented solutions. In this paper, we propose a method to improve the balanced energy consumption of each node. A node collects evaluated information until a defined distance from the triple information of neighbor nodes that are the energy consumption, hop counts, and transmitted counts. If a result from an evaluation function exceeds the critical values, the routing paths are renewed. We show the effective balanced energy consumption on a security level of PSM by the proposed method.
