“…Several TPC algorithms have been proposed that minimize power consumption for transmissions by having receivers measure received power and transmit the measurements back to transmitters [6], [7], [12], [24], [25], [26], [27], [28] [29], [30]. In [6], transmission power is controlled on the basis of short and long term estimations of wirelesslink states.…”

“…In [27], [28], transmission power is inversely proportional to received power. The algorithm in [29] selects relays on the basis of received power to improve connectivity, and the algorithm in [30] has the base station identify time instants of low attenuation to schedule sensors' transmissions on an opportunistic manner. It achieves a power consumption of 15 mW and PDR of 99% according to simulation results.…”

Wireless body area networks (WBANs) are characterized by large fluctuations in channel losses due to body shadowing. These fluctuations follow the patterns of the user's body movements. For example, in the case of walking and running, channel losses follow cyclical patterns. This paper presents an algorithm for transmission power control (TPC) and dynamic routing in WBANs when the user performs periodic body movements. The objective of the algorithm is to decrease the average power consumption to deliver packets to a common sink provided that a desired packet delivery rate (PDR) is guaranteed. This problem is important in WBANs given that replacing batteries is detrimental to several applications of WBANs, especially when sensors of the WBAN are implanted on the user's body. To the best of our knowledge, the proposed algorithm is the first to consider the joint problem of TPC and dynamic routing while not relying on non-local data (i.e., measurements of received power). This characteristic is important because traditional algorithms rely on data not local to transmitters, so these data have to be transmitted, consuming power unnecessarily. Traditional algorithms are also limited to the star topology only, so routing is not considered, which decreases network connectivity and transmission-power savings. The proposed algorithm is implemented on a WBAN of Shimmer wireless sensors. Experimental results show a reduction in power consumption of 23.4% to 50.4% when compared against transmissions at maximum power and a PDR within 5.6% of the desired value. The power consumption of the overhead of the proposed algorithm can be as small as 11% of that one of traditional algorithms. The algorithm's complexity is shown to be O(N 3), where N is the number of sensors. Finally, the algorithm is compared with traditional algorithms which reduce power consumption by 39.0% on average at most.

One of the major applications of Wireless Body Area Networks (WBANs), and the Internet of Things is the Electronic Health-Care systems. The progress in WBANs, and implanted health monitoring technologies have strong potential to alter the future of healthcare services by enabling ubiquitous monitoring of patients. An energy-efficient protocol is an important factor in the operation of eHealth care systems. A hybrid energy-efficient routing protocol is proposed in this paper for the distributed wireless body area network. In which a hybrid communication method and a new synchronization scheme are discussed. The hybrid communication enhances the network lifetime, and the synchronization scheme will consume less energy by avoiding collisions. The performance of the proposed protocol is analyzed, and it is compared with three baseline routing protocols at the 2.4 GHz ISM band with two ultra-low power transceivers.

“…It has been shown in [15,16] that the unfairness problem of resource allocation is resulted from the large difference of the distance from the end users to the BS. Although the MTCDs installed in/on the human body have almost the same distance to the PB as well as to the UE, clothes on body, human tissues, and human posture changes can cause significant signal attenuation with shadowing duration of 80 ms [23]. e different shadowing for the WPT and the WIT links may incur the unfairness problem again, as it is an inherent problem with respect to the channel quality.…”

This paper proposes a bargaining game theoretic rate allocation scheme for wireless-powered machine-type communications (MTCs). In the considered body area MTC network (MTCN), a battery-powered user equipment (UE) acting as the MTC gateway (MTCG) is responsible for collecting the information uploaded by in/on body wireless-powered MTC devices (MTCDs). By solving the Nash bargaining solution (NBS) of the proposed cooperative game, the minimum rate requirements of the MTCDs are satisfied. In addition, the network resource can be allocated to the MTCDs in a fair and efficient manner regarding the difference of their channel qualities. In comparison to other traditional resource allocation methods, the simulation results show that the proposed NBS-based method obtains a good tradeoff between the system efficiency and per-node fairness.
