An Event Driven Energy Efficient Data Reporting System for Wireless Sensor Network

In Wireless sensor networks (WSN), researchers are showing tremendous interest because of their potential usage in various applications. Sensor nodes are inexpensive and portable devices with some constraints of limited processing power and energy resources. Sensor nodes are deployed in the form of network to collect information from the environment, after collecting data they process this data and transmit the processed data to the user. As sensor devices are battery driven therefore power conservation is important in order to extend the life time of the sensor network. Nowadays, Clustering in wireless sensor network, which enables a group of sensors to work closely to form a single cluster head, has been a flourishing research field. When sensor nodes forward their data to base station (BS) via cluster heads, it may happen that the cluster heads closer to the base station are burdened with heavy relay traffic and which may results into early death of the node, leaving areas of the network uncovered and network partition. To address the problem, we are proposing an event driven redundant data elimination system which uses innetwork data processing before transferring data to cluster head (CH) or sink (BS). Our simulation results shows that our data reporting system along with routing scheme reduces the transmission loss and increase the network life time.
