The effect of the mobile station step size on lifetime of wireless sensor networks

Due to resource constraints in wireless sensor networks, always the increasing the lifetime of these networks by reducing the energy consumption have been attractived. Most energy of a network’s node is consumed to transmit data to the base station. In iterative routing based on clustering, only cluster heads transmit data to the base station which decreases heads’ energy drastically. in recent years, For decrease of consuption energy of cluster heads, mobile network base station is proposed.In this paper, presented a new algorithm using fuzzy logic which the the central station moving on a circular path with fixed size and different steps and with simulation the effect of increasing and decreasing step motion is analyzed.
