Green Communication in Wireless Body Sensor Network—A Review

Abstract

In trending research domains, wireless sensor network has become an emerging area in domains like green communication, health monitoring, smart energy home, building automation, etc. Wireless sensor node possesses limited processing capability, storage, and energy resources. Wireless body area network (WBAN) is a new arena in the wireless sensor network intended to provide a cutting edge in healthcare applications and useful in managing the abnormalities in parameters like ECG, respiration and temperature, and soon. The extant of sensor network for prolonged period is hinged on the amount of energy consumed during its operation. The power cost is dependent on the lowest consumption of power at the wireless sensor nodes which also empowers the enhanced energy efficiency. Green communication is an essential mechanism to improve the life span of WBAN. In this paper, major algorithms pertaining to various layers of WBAN architecture and few techniques that are leading to green communication are discussed.
