A novel approach for lifetime analysis of sensor network using fuzzy logic

Lifetime enhancement has always been of crucial importance for energy constrained sensor network due to resource limitations of sensor nodes. In the recent past some researchers have suggested mobile sink method to enhance the lifetime of sensor network. Most of the energy is consumed in data transmission from sensor nodes to the base station. This is the main reason for energy dissipation in wireless sensor network. This energy dissipation can be minimized by using mobile base station. Motion of the base station can be effectively governed by fuzzy logic based method. In this paper lifetime of wireless sensor network has been analyzed in which base station is free to move over a square shaped path. Simulation results show that this scheme in which base station is moving over square shaped path gives better lifetime than other existing schemes.
