Wireless Body Sensor Networks (WBAN) are a special case of wireless sensor networks (WSN), developed to operate at the human body scale. Thus, energy efficiency is one major aspects that must be taken into consideration before designing any WBAN solution, because change batteries could very difficult, especially when sensors implanted inside body. For this reason, several research projects have been carried out on adoption harvesting schemes, aim collect from sources surrounding (sun, warmth, movements, heartbeat, RF radiation ...) and transform it an electrical power nodes WBAN. Nevertheless, harvested also better exploited, given temporal variation nature these alternative sources. The purpose paper present general overview as well methods in literature focusing optimizing exploitation WBAN, through Mac, routing or physical layer protocols.
