Cooperative Communication based: Efficient Power Allocation for Wireless body Area Networks

Wireless Body Area Networks (WBAN) are proposed to offer health-care to patients on the move, and monitor patients' health. In WBAN, several sensors located between the transmitter and the receiver that can help and relay source sensors data to improve the communication quality. Sensors in WBAN paradigm are small and equipped with limited battery, thus energy and power are scary factor. In this work and based on the cooperative communication, we found efficient power allocation of the three transmission mode (cooperative communication mode) over Rayleigh channel fading.
