A MAC protocol for reliable communication in low power body area networks
Abstract Wireless Body Area Networks (BAN) are supposed to operate in very low transmit
power regime in order to keep the Specific Absorption Rate (SAR) low. Low power
transmissions are known to be very error prone. However, high reliability of communications
is needed for several healthcare applications. It has been observed that the fluctuations of
the Received Signal Strength (RSS) at the nodes of a BAN on a moving person show certain
regularities and that the magnitude of these fluctuations are significant (5–20 dB). In this …
