Abstract
In this paper, the average throughput maximization challenge with resources fairness consideration is proposed. In a multipoint wireless body area network (MP-WBAN), the time switching (TS) strategy and fairness algorithm are studied to improve system resources allocation performance. Under extreme circumstances, the sensors transfer command signals to the access point (AP) requesting the radio frequency (RF) energy from the source node. On the other hand, the sensors attached to the body surface transmit the perceived physiological information to the AP node. Owing to distance-dependent signal attenuation, the sensors near the AP node harvest more RF energy and time slots to achieve higher throughput. On the contrary, the sensors farther from the source node receive fewer RF energy and time slots to obtain lower throughput. Therefore, we design the common throughput maximization algorithm to allocate more time to farther sensors. At last, the effectiveness and accuracy of the studied fairness scheme are verified by simulation experimental data.

Summary
With the rapid development of ultra-high speed, low latency and high reliability 5th-generation (5G) technology, wireless body area networks (WBANs) with information sensing, processing, and transmission functions have once again caused a wave of research in the whole society [1]. RF signal technology is the most effective mean of energy transmission for WBANs, and it helps the network to work reliably in real time [3], [4]. In the bidirectional relay cooperative network, the authors design two different EH strategies including discrete and continuous time slots to optimize system energy efficiency [6]. In a three-node MIMO network with radio signal energy transmission, the authors study two kinds of information reception situations including. Based on the existing relay cooperation networks, the authors innovatively introduce direct links to adaptively improve system performance in simultaneous wireless information and power transfer (SWIPT) systems [17]. In the case of inter-network interference, the authors reduce the complexity of the scheme and improve energy efficiency by solving nonlinear programming problems.
