The Wireless Body Area Network (WBAN) shows potential as a technology that can provide high-quality healthcare services to its users. However, the limited battery life of low-power devices attached to the body is a challenge. The data must be sent through a reliable connection with minimum delay to the healthcare centre since it directly influences user satisfaction. In case of potentially fatal situation, transmitting data at the right time is important. Therefore, more policies and methods for better end-toend performance of a network are required. In this paper, the end-to-end delay of network over a wireless channel from sensor to healthcare centre has been analyzed. The proposed work presents an Enhanced Quality of Service Aware Routing Protocol for Delay Sensitive Data (EQRD). EQRD reduces the delay by proposing a Bandwidth Utilization Constant to maximize the utilization of channel capacity. It finds the best minimum number of slots that can be used for data transmission for the minimization of delay and maximization of throughput. By analyzing various parameters, the EQRD protocol's effectiveness was evaluated in relation to other delay-aware routing protocols. The findings indicate that the proposed protocol has superior performance with regards to throughput, energy efficiency, and delay.

“…In contrast to the wireless sensor network (WSN), the WBAN introduces new challenges and features, replacing wired and complex healthcare equipment, thereby allowing continuous monitoring of crucial data while limiting the user's mobility [3]- [5]. The performance of WBAN relies on the design of medium access control (MAC) protocols [6], [7]. In WBAN communication, MAC protocols are categorized into contention-based, scheduled-based, and hybrid-based access methods [8], [9].…”

In recent years, the demand for wireless body area network (WBAN) technology has increased, driven by advancements in medical and healthcare applications. WBAN consists of small, low-power, and heterogeneous sensor devices attached inside or outside the body for continuous health monitoring. Medium access control (MAC) is pivotal in addressing WBAN challenges by ensuring reliability and energy efficiency under a dynamic environment caused by body movement. Therefore, to tackle these challenges, this paper presents a MAC protocol based on time division multiple access (TDMA) to enhance the WBAN performance. The proposed TDMA-MAC protocol employs a one-periodic scheduled-based access method to provide reliable data transmission while satisfying the WBAN requirements. The proposed protocol is compared to the IEEE 802.15.6 MAC, enhanced packet scheduling algorithm MAC (EPSA-MAC), and concurrent MAC (C-MAC) protocols based on the performance metrics of packet delivery ratio (PDR), network throughput, energy consumption, and average delay. The simulation results show that the TDMA-MAC protocol outperforms its competitors as it could achieve up to 98% PDR, 30% enhanced throughput, 30% energy optimization, and 20% improvement in average delay.

“…The medium access control (MAC) layer is crucial to meet WBAN concerns such as resource allocation, protocol overhead, collision prevention, overhearing, idle listening, packet delay, congestion control, reliability, retransmission, and congestion control [5]. Thus, its design significantly impacts overall WBAN performance [6].…”

<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>
