Enhanced LEACH Multipath Based Energy Efficient Routing for Wireless Sensor Network

Abstract: Wireless sensor networks are widely used in many applications now days. WSN�s equipped with large number of wireless sensors programmed to sense physical parameters and transmit to remote location. Sensors composed of battery having limited power constraint. This lead many routing protocols designed for WSN to use energy efficiently. One of the most popularly used energy efficient clustering protocol is LEACH. In this work we propose multipath LEACH protocol based on LEACH. The main intention of this protocol is to offer energy efficient and robust communication. This is achieved by traffic multiplexing over multiple paths and introducing alternation of the cluster-heads for every given interval of time.

Keywords: Wireless sensor network, LEACH, energy efficient, Multipath.
