A NOBLE ENERGY SCAVENGING TECHNIQUE FOR WIRELESS BODY AREA NETWORK

Abstract

Wireless Body Area Networks (WBAN) present a variety of Power Management challenges ranging from radio protocols, to node components.One of the most important constraints is the energy efficiency problem.This paper addresses the issue of power consumption in the field of Wireless Body Area Networks (WBAN). It presents a methodology used to perform real-time measurements of the energy consumption of a deployed WBAN. Body Area Networks (BANs) are widely used mainly for healthcare and fitness purposes. In both cases, the lifetime of sensor nodes included in the BAN is a key aspect that may affect the functionality of the whole system. Typical approaches to power management are based on a trade-off between the data rate and the monitoring time. The biggest challenge in use of WBAN is the battery power requirement.
