A New Bollinger Band Based Energy Efficient Routing For Clusteredwireless Sensor Network

Abstract

Designing of scalable routing protocol with prolonged network lifetime for a wireless sensor network(WSN) is a challenging task. WSN consists of large number of power, communication and computationalconstrained inexpensive nodes. It is difficult to replace or recharge battery of a WSN node when operatedin a hostile environment. Cluster based routing is one of the techniques to provide prolonged networklifetime along with scalability. This paper proposes a technique for cluster formation derived from “Gridbased method”. We have also proposed a new decentralized cluster head (CH) election method basedon Bollinger Bands. Bollinger Bands are based on Upper Bollinger Band and Lower Bollinger Band, bothof these bands are extremely reactive to any change in the inputs provided to them. We have used thisproperty of Bollinger Bands to elect CH. Simulation result shows significant improvement in the networklifetime in comparison with other decentralized and ant based algorithms.
