Wireless body area sensor network is a sub-field of wireless sensor network. Wireless body area sensor network has come into existence after the development of wireless sensor network reached some level of maturity. This has become possible due to the tremendous technological advancement leading to easy-to-use wireless wearable technologies and electronic components that are small in size. Indeed, this field has gained significant attention in recent time due to its applications which mostly are toward healthcare sector. Today, tiny-sized sensors could be placed on the human body to record various physiological parameters and these sensors are capable of sending data to other devices so that further necessary actions could be taken. Hence, this can be used for diagnosis of disease and for developing serious healthcomplication alert systems. Considering this recent hot topic, the intent of this work is to present the state-of-the-art of various aspects of wireless body area sensor network, its communication architectures, wireless body area sensor network applications, programming frameworks, security issues, and energy-efficient routing protocols. We have tried to cover the latest advancements with some discussion on the available radio technologies for this type of network. Future visions and challenges in this area are also discussed.

“…It is worth noting that only a few surveys have investigated the usage of LPWAN communication technologies in HCM applications, while its suitability and utilization is yet to be considered at the intersection of WBAN and HCM. For examples of the existing surveys that investigated the legacy short-range data communication technologies used in WBANs, see [5,6,7,8,9,10,11,12,13,14,15]. However, a review of LPWAN technologies for WBAN solutions based on HCM applications does not exist in the literature to the best of the authors’ knowledge.…”

In ubiquitous health-care monitoring (HCM), wireless body area networks (WBANs) are envisioned as appealing solutions that may offer reliable methods for real-time monitoring of patients’ health conditions by employing the emerging communication technologies. This paper therefore focuses more on the state-of-the-art wireless communication systems that can be explored in the next-generation WBAN solutions for HCM. Also, this study addressed the critical issues confronted by the existing WBANs that are employed in HCM. Examples of such issues include wide-range health data communication constraint, health data delivery reliability concern, and energy efficiency, which are attributed to the limitations of the legacy short range, medium range, and the cellular technologies that are typically employed in WBAN systems. Since the WBAN sensor devices are usually configured with a finite battery power, they often get drained during prolonged operations. This phenomenon is technically exacerbated by the fact that the legacy communication systems, such as ZigBee, Bluetooth, 6LoWPAN, and so on, consume more energy during data communications. This unfortunate situation offers a scope for employing suitable communication systems identified in this study to improve the productivity of WBANs in HCM. For this to be achieved, the emerging communication systems such as the low-power wide-area networks (LPWANs) are investigated in this study based on their power transmission, data transmission rate, data reliability in the context of efficient data delivery, communication coverage, and latency, including their advantages, as well as disadvantages. As a consequence, the LPWAN solutions are presented for WBAN systems in remote HCM. Furthermore, this research work also points out future directions for the realization of the next-generation of WBANs, as well as how to improve the identified communication systems, to further enhance their productivity in WBAN solutions for HCM.

In this paper, we investigate an energy harvesting wireless body area network (WBAN) with relay cooperation, where the destination nodes and the relay simultaneously harvest energy from the radio frequency (RF) source, then the destination nodes transmit data to the source by maximum ratio combining (MRC) transmission mode. We study the optimal design for relay power splitting ratio in each relaying sub-slot and the destination nodes power allocation to maximize the sum-throughput with the proposed protocol. The optimization problem is divided into two cases, destination node power limit (DPL) case and relay power limit (RPL) case. In essence, the problem is a joint-objective optimization and is solved by the Lagrangian multiplier method. Simulation results show that our proposed optimal method can greatly improve the sum-throughput compared with conventional mean power allocation (MPA) method and mean time allocation (MTA) method. Moreover, a significant sum-throughput promotion is achieved on the RPL case over the DPL case.INDEX TERMS Relay cooperation, energy harvesting nodes, optimal power allocation protocol, sum-throughput, WBAN.
