“…To provide the desired QoS, a traffic-aware MAC (TA-MAC) protocol utilizes the IEEE 802.15.4 standard and dynamically distributes time slots following the traffic priority [43]. Furthermore, to meet the QoS needs of emergency traffic, a scheduling technique called priority-weighted round robin (PWRR) is created [44] based on the IEEE 802.15.6 standard.…”

<span>The widespread adoption of wireless body area network (WBAN) in healthcare presents opportunities to meet the increasing demand for medical services. WBAN enables continuous real-time (RT) monitoring through biomedical sensor nodes positioned in or around a patient's body, collecting vital physiological data. In addition, WBAN imposes stringent criteria for energy efficiency and reliability throughout data collection and transmission. This review paper places significant emphasis on the fundamental concept and essential characteristics of WBAN technology. First, the WBAN features, including architecture, sensor nodes types and network topology is presented. Then, the study explores a wide variety of communication standards and multiple access (MA) mechanism deployed in this technology. Moreover, it discusses open research and challenging issues such as heterogeneous traffic, quality of services (QoS), energy consumption, reliability, interference management, and human body movements effect. Finally, the paper is concluded, and future directions are identified in this evolving field of human health monitoring technology.</span>

“…Additionally, the amount of sensing data to transmit varies, depending on the monitoring target. Therefore, a static allocation of wireless resources and an identical allocation strategy for each node is inappropriate, reducing network throughput [14]. It is necessary to allocate wireless resources dynamically to sensors with data to transmit in dense WSNs to improve network throughput.…”

This paper presents a novel dynamic slot allocation algorithm for wireless sensor networks designed to overcome resource constraints. Our algorithm operates without explicit request messages and adapts the transmission period and data transmission amount according to changes in the monitored environment. As such, it addresses the challenge of allocating wireless resources efficiently and fairly while considering packet drop rate, transmission delay, channel status, and transmission opportunities. However, networks with limited resources can only collect and process some of the necessary information for optimal allocation. Therefore, our proposed scheme uses accumulative information on allocated resources instead of additional overhead information. Our algorithm outperforms the reservation-based resource allocation scheme in conditions where packet arrival rates change dynamically, which achieves over 15% improvement in terms of network throughput, indicating its suitability for networks operating under constrained resources.

Motivated by the increasing need for improved healthcare solutions, Wireless Body Area Networks (WBANs) have shown their great potential in revolutionizing the next generation healthcare through enabling continuous monitoring of health status with early detection of abnormal situations. Such networks are able to support a diverse range of applications with traffic rates ranging from several bits per hour up to 10 megabits per second. For the efficient functionality of these applications, each one poses a specific set of Quality of Service (QoS) requirements to the Medium Access Control (MAC) sub-layer including transmission reliability, timeliness and throughput. However, energy limitations of WBANs make the satisfaction of these requirements a challenging task. The current paper aims to explore the application trends of WBANs in the health field as well as the salient features of the MAC protocols proposed for this class of networks, and to provide a general rule indicating the most suitable MAC technology for WBANs based on the characteristics of the targeted application.
