HIERARCHICAL ZONE BASED STABLE POWER OPTIMIZATION IN WIRELESS SENSOR NETWORK

ABSTRACT In this paper we purpose the mobility of a sink in improved energy efficient PEGASIS-based protocol(IEEPB) to advance the network lifetime of Wireless Sensor Networks(WSN).In this a multi chain model having a sink mobility is proposed to achieve proficient energy utilization of wireless sensors . The motorized movement of mobile sink is steered by petrol or current, there is a need to confine this movement to a boundary and in a fixed trajectory. An Algorithm is being developed for the trajectory of mobile sink. Keywords –Wireless Sensor Networks, Sink Mobility
