An Energy Efficient Data Collection Scheme for Multiple Sinks in Wireless Sensor Network

In a multi-hop WSN a sensor node spends most of its energy for relaying data packets due to which energy reduction is one of the major issue in the designing of a wireless sensor network to prolong the lifetime of a network. One of the solutions of this problem is to shorten the hop distance a sensor?s data that has to travel until reaching the sink. These distances can be reduced effectively by deploying multiple sinks instead of one and every sensor communicates with its closest sink. We also develop EL(energy and lifetime) to be closely integrated with compressive sensing, an emerging technique that promises considerable reduction in total traffic cost for collecting sensor readings under loose delay bounds. Finally, we systematically evaluate performance graph to compare its performance with default placement and optimal placement.
