Abstract

In this paper we introduce issues relevant to understanding of the human body as a medium for radio frequency (RF) navigation of smart robots travelling inside the body for wireless medical applications. We provide the results of Cramer Rao Lower Bound (CRLB) for in-body localization using received signal strength (RSS) and we highlight challenges demanding further research for attaining more precise localization inside body using time-of-arrival (TOA) techniques.
