A survey of power efficient technologies for Wireless Body Area Networks.

Wireless Body Area Networks (WBANs) of intelligent sensors emerged as the most promising architecture for ambulatory health monitoring. Integrated in an m-Health system they provide means for unobotrusive ubiquitous monitoring. However, proper design of wireless communication system is application dependent and critically influences system performance and user acceptance. In this paper we present a survey of existing and emerging wireless communication technologies and critical parameters for the system design.
