Abstract :
Wireless Body Area Networks is an application of wireless sensor network that is used in health monitoring. The wireless sensor nodes are either placed inside or on the body and collected the physiological data. In this paper we discuss about location based TOA algorithm for wireless UWB sensor notes in the body area. We measured the TOA ranging error in a typical body area environment and analyzed sources of inaccuracy in TOA based body area localization system. The simulations show the effects of proposed TOA ranging on human body.
