Sensor networks are highly sensitive to energy usage. They may, probably, be deployed in inhospitable or hostile environments, where it may not be possible to refresh energy sources. Hence, energy consumption is a major issue, and energy-aware protocols/applications are desirable. Energy consumption is observed at three stages, node communication, sensing and processing. A wireless sensor network is a special kind of wireless network consisting of small and spatially distributed autonomous devices (nodes) which can cooperatively sense physical phenomena around them. Each node in the sensor network may consist of one or more sensors, a low power radio, portable power supply, and possibly localization hardware.
