Performance Analysis and Evaluation of Wireless Sensor Network using LEACH and HEED

In Wireless sensor network (WSN) lifetime of sensors is a critical issue because the sensor nodes having limited power. Therefore, organization of nodes in a proper manner (clustering) becomes one of the major techniques to expand the lifetime and improve the throughput of the network. In this paper we propose a Hybrid Energy Efficient Distributed Protocol (HEED) for clustering in Sensor Network to improve the lifetime of network. The simulation result show that the propose scheme has higher network throughput in terms of higher data packets received than existing LEACH protocol
