Sensor nodes in Wireless Sensor Networks (WSNs) are normally battery-powered and remain stationary after initial deployment. Sensor nodes direct the sensed data back to sink via multi-hop links. While reporting tasks, sensor nodes nearby the sink will consume more battery power than other sensor nodes for forwarding their own sensed data and others data; subsequently battery power of these nodes will drain out early and cut down the network lifespan. Sensor nodes will no longer provide sensing and data processing, if it runs out of energy.
