In this paper, a dynamic clustering algorithm for mobile wireless sensor networks, the MADCA has been proposed. The proposed clustering methodology MADCA is hierarchical, dynamic and energy-efficient algorithm for mobile wireless sensor network. MADCA forms multiple clusters with each cluster having one cluster head and two deputy cluster heads. The sensor nodes start collecting the data only when the base station comes in range with the cluster head. The performance of the proposed algorithm has been evaluated through simulations and the results have been compared with the existing LEACH-M algorithm. MADCA shows drastic reduction in average communication energy when compared to LEACH-M. The network lifetime has been found to be greatly prolonged in MADCA. The node death has been found to be greatly reduced in the proposed algorithm. Thus the proposed clustering methodology has been found to be greatly useful when both the sensor nodes as well as the base station are mobile.
