Jerald Yoo
Abstract
A body area network (BAN) provides connectivity and power among on-body/in-body sensors and is an attractive means for realizing the “human intranet” for health-care, medical, or multimedia applications around the human body <xref ref-type="bibr" rid="ref1" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">[1]</xref> , <xref ref-type="bibr" rid="ref2" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">[2]</xref> .
