A Novel LEACH Based Protocol for Distributed Wireless Sensor Network

Abstract

A sensor node, also known as a mote (chiefly in North America), is a node in a sensor network that is capable of performing some processing, gathering sensory information and communicating with other connected nodes in the network. A mote is a node but a node is not always a mote. Each sensor node has a microprocessor and a little amount of memory. Also every sensor node is outfitted with one or more sensing devices such as acoustic sensors, microphone arrays, video cameras, infrared, seismic or magnetic sensors. But it is difficult to replace the deceased batteries of the sensor nodes. A distinctive sensor node consumes a great deal of its energy during wireless communication. This research work suggests the development of a well evaluated distributed clustering scheme for dense wireless sensor network fields, which gives improved performance over the existing clustering algorithm LEACH. The two thrashing concepts behind the proposed scheme are the hierarchical distributed clustering mechanism and the concept of threshold. Energy utilization is appreciably reduced, thereby greatly prolonging the lifetime of the sensor nodes.
