STUDY OF LOAD BALANCING TO MINIMIZE THE VARIABLE NODE POWER FOR INCREASING THE NETWORK LIFETIME IN WSN

Abstract

Wireless technology growing rapidly now a days. Information congregation is a rapid increasing and challenging field in today’s world of computing. This interacts with the various kinds of Things, Objects, Technological devices, Sensors in various fields. Wireless sensor networks consist of small battery powered devices with restricted energy resources. The main merit of the sensor network is that it includes power utilization constraint for sensor nodes with the help of battery life. The sensor nodes are typically out of the way for the user; therefore substitution of the energy source or battery is not practicable. For this reason, energy efficiency is a main design concern that wants to be improved in order to extend the lifetime of the sensor network. To extend the lifetime of sensor nodes, energy utilization and routing design issues are considered. The clustering based approach for communication is conceived as the mainly appropriate for the wireless sensor networks. The most important monitoring system is wireless sensor networks. All of the sensor nodes act as an event detector as well as a data router. It consists in selecting a set of cluster heads from the set of sensor nodes. The cluster members transmit the data to the cluster head and all received data at cluster head is aggregated and transmit it to the base station. Clustering reduces and balances the energy utilization and prolongs the lifetime and scalability of the wireless sensor network. Clustering is frequently used with a data aggregation method. Proposed method is work in three phases; Initialization Phase, Setup Phase, Transmission Phase.
