Emerging body-wearable devices for continuous health monitoring are severely energy constrained and yet required to offer high communication reliability under fluctuating channel conditions. Such devices require very careful management of their energy resources in order to prolong their lifetime. In the authors' earlier work, they had proposed dynamic power control as a means of saving precious energy in off-the-shelf sensor devices. In this paper, they experiment with a real body-wearable device to assess the power savings possible in a realistic setting. They quantify the power consumption against the packet loss and establish the feasibility of dynamic power control for saving energy in a truly-body-wearable setting.
