EECP: Energy Efficient Clustering Using Pegasis in Wireless Sensor Network

In Wireless Sensor Network (WSN), sensor nodes have limitations of energy, so the lifetime of the network is directly proportional to energy factor. All kinds of obstacles exist in the sensing field. Hence the challenge is to determine the obstacle avoiding shortest path with energy efficient clustering. EECP (Energy Efficient Clustering using PEGASIS) presents energy efficient routing by reducing the dead nodes based on clustering using PEGASIS (Power Efficient Gathering in sensor Information System). In cluster based routing mechanism, some nodes elected as cluster heads to collect the data from cluster members and transfer to the mobile sink. Mobile sink collects data from cluster heads to perform data aggregation, fusion and transmission. Therefore we present a heuristic tour planning algorithm based on spanning graph to find obstacle avoiding shortest path. EECP works in combination with STEM (Sparse Topology and Energy Management) protocol to have efficient power consumption. Simulation results verify the effectiveness and comparative performance of both existing and EECP methodology in terms of network lifetime and power consumption.
