Network adaptive round-time clustering algorithm for wireless sensor networks

In recent time, wireless sensor networks are gaining popularity among research persons. Wireless sensor networks are energy constraint networks because sensor nodes carry limited energy. Energy efficiency is the prime design issue for wireless sensor networks. Clustering algorithms increase performance of network with reduction in energy consumption of nodes. Clustering operation is performed in rounds to load balance the network. Duration of round-time is decisive for performance of clustering algorithms. Most of existing clustering algorithms have fixed round-time and do not consider network dynamics. In this paper, network adaptive variable round-time solution is presented. In proposed solution, round-time is calculated according to number of nodes alive in the network. Simulation results show that the proposed solution increases the network lifetime and data units received at base station.
