ABSTRACT
For an increasing number of people living with chronic medical
conditions, wearable wireless sensor devices can provide nonin-
trusive yet continuous physiological monitoring, allowing effective
clinical management without compromising quality of life. Truly
non-intrusive 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 chapter 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.
