As an information collecting means to grasp the damage situation in an environment where communication is unstable, internal situation such as underground malls and subway premises is hard to confirm when a disaster occurs, we have been studying a system gathering disaster area information by utilizing the rescue robot and Wireless Sensor Network (WSN) built on Mobile Sensor Nodes (MSN). This paper proposes MSN arrangement method to maintain wireless communication connectivity considering a long-time operation of the network. The MSN compares evaluation values of communication quality and remaining energy level with the neighbors and moves to a suitable location maintaining the communication connectivity. The Simulation of change of energy consumption by several communication settings is conducted to confirm the usefulness of the proposed method.
