Wireless Sensor Networks (WSN) consist of a large number of battery-powered devices (nodes), which transmit their data to a central node called the sink. Multi-hopping techniques are used to deliver the sensed data to the sink. The nodes that are close to the sink receive high volume of data from the rest of the network, and they have to forward these data to the sink. As a result, these nearby nodes drain their batteries and die quicker than other nodes in the network.
The Energy Aware Sink Relocation (EASR) is a method that prolongs the life of sensors by moving the sink to various locations in the network. By not keeping the sink at any specific location for too long, EASR improves the lifetime of sensors. This project presents an application of EASR to multi-sink networks. Simulation results show that the proposed method extends battery life of the network nodes.
