Body-Area-Network transmission power control using variable adaptive feedback periodicity

We propose a class of adaptive power control protocol, where the period between each feedback transmission is adaptively varied to accommodate run-time variation in the quality of each channel. Initial analyses suggest that transmission control protocols with adaptive feedback periodicity can outperform other comparable schemes. For certain measured channels the period can increase to once every few minutes (thousands of packets) and still provides substantial power savings. Adaptive power control protocols also provide the potential to reduce intra-cell interference.
