“…In cases where energy harvesting technologies are employed, related works have proposed adaptive protocols that deal with the challenge of providing the required quality of service under spatio-temporal uncertainty in the energy input [23][24][25][26]. For an in-depth survey on WBANs, we refer the reader to [27] and [28]; whereas [29] presents a survey on WBANs with special interest in eHealth.…”

Demographic changes such as the ageing population and the continuous rise of chronic medical conditions such as obesity, diabetes and depression make our healthcare systems economically unsustainable. Sensing technologies are promising solutions that can provide cost-effective answers to these challenges. In this paper, we focus on long-term in-house activity monitoring that aims at early detection and prevention of such conditions. In this context, we present and experimentally evaluate an ultra low-power (less than 100-μW long-term average power consumption) on-body activity sensing prototype system that is based on Bluetooth low energy (BLE). As part of a larger smart home monitoring architecture, the role of the presented system is to collect and reliably deliver acceleration data to the upper layers of the architecture. The system evaluation incorporates a thorough power consumption study that facilitates meaningful battery lifetime estimations, an insightful coverage study in an actual residential environment, and the investigation of energy-efficient packet loss mitigation techniques.

“…By this process, the energy consumption is reduced and increases the chance of data transmission higher in terms of data reliability energy of a human, uses ID-polling timeslot for emergency data and the probabilistic contention (PC) for normal data [60]. The body coordinator node is placed in the center and assigns the Monitoring Interval (MIT ID-BN ) to each body node (BN) in assisting to calculate the packet Inter-Arrival Time (IAT BN ) and constant energy harvesting rate (KEH).…”

“…However, the packet collision occurs if more than one node have the same threshold values for data transmission, whereas the energy consumption of the nodes become high. The [60] protocol does not predict in advance which node detects an emergency and non-emergency data to allocate slots for data transmission accordingly. During data collision, the body coordinator adjusts the threshold values of the sender sensors to build a gap between their timing and data transmission.…”

Health monitoring using biomedical sensors has witnessed significant attention in recent past due to the evolution of a new research area in sensor network known as Wireless Body Area Networks (WBANs). In WBANs, a number of implantable, wearable, and off-body biomedical sensors are utilized to monitor various vital signs of patient’s body for early detection, and medication of grave diseases. In literature, a number of Medium Access Control (MAC) protocols for WBANs have been suggested for addressing the unique challenges related to reliability, delay, collision and energy in the new research area. The design of MAC protocols is based on multiple access techniques. Understanding the basis of MAC protocol designs for identifying their design objectives in broader perspective, is a quite challenging task. In this context, this paper qualitatively reviews MAC protocols for WBANs. Firstly, 802.15.4 and 802.15.6 based MAC Superframe structures are investigated focusing on design objectives. Secondly, different multiple access techniques such as TDMA, CSMA/CA, Slotted Aloha and Hybrid are explored in terms of design goals. Thirdly, a two-layered taxonomy is presented for MAC protocols. First layer classification is based on multiple access techniques, whereas second layer classification is based on design objectives and characteristics of MAC protocols. Critical and qualitative analysis is carried out for each considered MAC protocol. Comparative study of different MAC protocols is also performed. Finally, some open research challenges in the area are identified with initial research directions.

“…QoS is another important feature of a suitable MAC protocol for WBANs, which includes delay variation and point-to-point delay [35]. The authors of [36] have designed an energy-aware MAC protocol, namely HEH-BMAC for energy harvesting, which allows for the behaviour of each WBAN to adapt to its energy level. The available energy at each time instant will be an accumulation of the energy harvested as well as the energy stored in the battery.…”

Enabling interference-aware and energy-efficient coexistence of multiple wireless body area networks with unknown dynamics

This paper presents an adaptive interference mitigation scheme for multiple coexisting wireless body area networks (WBANs) based on social interaction. The proposed scheme considers the mobility of nodes within each WBAN as well as the relative movement of WBANs with respect to each other. With respect to this mobile scenario traffic load, signal strength and the density of sensors in a WBAN are incorporated to optimize transmission time with synchronous and parallel transmissions to significantly reduce the radio interference and energy consumption of nodes. This approach leads to higher packet delivery ratio (PDR) and longer network lifetime even with nodes dynamically moving into and out of each others interference region. We make channel assignment more energyefficient and further reduce power consumption using transmit power control with simple channel prediction. Simulation results show that our approach maintains optimum spatial reuse with a range of channel dynamics within and between coexisting BANs. This protocol based on social interaction is shown to mitigate interference and minimize power consumption, and increase the spatial reuse and PDR of each WBAN, while increasing network lifetime. In the context of the adaptive interference mitigation scheme proposed, this paper also reviews the state of art in literature on mobility, MAC layer and power control solutions for WBANs, as well as providing a summary of interference mitigation schemes previously applied in WBANs.
