An important constraint in wireless body area network (WBAN) is to maximise the energy-efficiency of wearable devices due their limited size and light weight. Two experimental scenarios; ‘right wrist right hip’ ‘chest with posture walking are considered. It analyzed through extensive real-time data sets that large temporal variations channel, a constant transmission power typical conventional control (TPC) methods not suitable choices for WBAN. To overcome these problems novel energy-efficient adaptive (APC) algorithm proposed adaptively adjusts (TP) level based on feedback from base station. The main advantages saving more energy acceptable packet loss ratio (PLR) lower complexity implementation desired tradeoff between savings link reliability. We adapt, optimise theoretically analyse required parameters enhance system performance. sequentially achieves significant higher 40.9%, which demonstrated by Monte Carlo simulations MATLAB. However, only limitation slightly PLR comparison TPC such as Gao's Xiao's methods.
