This paper concerns an efficient network configuration method of mobile nodes considering energy-balanced sensor networks. This method is based on the IEEE 802.15.4 standard. The MSBS method is proposed for performance enhancements of mobile nodes using depth, traffic, and RSSI information. The MSBS method can transfer trusted data and prevent traffic overloads from occurring at specific nodes. For the performance analysis, the information from the mobile nodes in sensor networks is investigated and analyzed using the proposed method. Simulation results show that the MSBS method provides an energy-efficient network configuration according to the mobility of nodes in sensor networks.
