One of the main challenges of wireless sensor network is maximization of the lifetime of the sensor node since the energy efficiency determines the lifetime of a sensor node, power consumption of the sensing device should be minimized. To conserve power, sensor node should shut off the power supply when not in use. In this paper, the authors present some energy efficient algorithms to enhance the network lifetime. By introducing sink mobility into wireless sensor networks, the network performance including lifetime, energy efficiency and end-to-end delay can be enhanced. Further, by increasing the number of sleep nodes using smack sets, the network performance can be greatly improved.
