For an increasing number of people living with chronic medical conditions, wearable wireless sensor devices can provide non-intrusive yet continuous physiological monitoring allowing effective clinical management without compromising quality of life. Truly nonintrusive sensor devices will have light weight and small form factor, placing fundamental constraints on the available energy, which necessitates very careful energy management at all layers. This paper investigates the opportunities and challenges in the use of dynamic radio transmit power control for prolonging the lifetime of such energy constrained body-wearable sensor devices.
