Energy efficient inter and intra cluster movement of mobile sink in wireless sensor network

Abstract

WSN has brought revolution in monitoring or examining the particular area of the network. It has acquired many sectors like agricultural sectors, smart cities (Smart grids, Sewage treatment plants) and automation industries etc. the most prominent concern of battery of the sensor nodes are reported to deal with the energy efficient solution but still there is a lot of scope in enhancing the network performance of the WSN. The sink mobility in a controlled scenario with optimized Cluster head selection after every round using PSO has improved the network performance. The proposed scheme beats the ICM in terms of stability period, lifetime and half node dead. Stability Period, Half Node Dead and Network lifetime has increased by 19.8%, 42.1% and 37% respectively. Standard average coverage time decreases with increase in network area size.
