The Current Status of Energy-efficiency for Wireless Sensor Networks
Lun Yu · Computer Knowledge and Technology · 2007
Wireless sensor networks (WSN) which has integrated the sensor technology, embedded computing technology and communication technology are useful in the unattended places. WSN can be used for various application areas (military and civil).A sensor network is composed of a large number of sensor nodes that are small and energy constrained. It is essential that how to reduce the energy that the nodes consume for prolonging the life of the network. The structure of WSN is briefly introduced. The current state of the art of energy-efficiency algorithms and protocols for sensor networks are captured in this article. Finally this article proposed the future development of energy-efficiency for WSN.
