An energy-efficiency index based on death probability for maximizing WBAN reward

ABSTRACT

This article presents a general energy-efficiency index aiming at maximising the network reward of energy-limited wireless body area network (WBAN). The energy-efficiency index utilises a probability which is named as death probability. The death probability is a function of channel state information (CSI), residual energy information (REI) and transmission power. Finally, the existing protocols using the death probability are summarised. The performance of the proposed protocol is evaluated through numerical results.
