Energy Efficient Routing for Wireless Sensor Network through Event-Based Clustering Mechanism

Sensor networks are collection of sensor nodes which co-operatively send sensed data to base station. As sensor nodes are battery driven, an efficient utilization of power is essential in order to use networks for long duration hence it is needed to reduce data traffic inside sensor networks, reduce amount of data that need to send to base station. As sensor nodes sense the data, process it, and send it to the base station, there are wide chances that the data generated from the neighboring sensors is often redundant and correlated. The unavoidable issue is that in large sensor networks, the amount of data generated is enormous for the base station to process. There is severe need of the methods for combining data into high quality information at sensors or intermediate nodes which can lead to the energy conservation by reducing the number of packets transmitted to base station. To achieve this, data aggregation approach has been explored and an innetwork data aggregation strategy has been proposed that is showing better results in term of energy consumption.
