Proactive and Reactive Transmission Power Control for Energy-Efficient On-Body Communications
In wireless body sensor network (WBSNs), the human body has an important effect on the performance of the communication due to the temporal variations caused and the attenuation and fluctuation of the path loss. This fact suggests that the transmission power must adapt to the current state of the li...
