“…The IEEE 802.15.4 MAC sublayer was considered in the design of the proposed algorithm as it supports video transmission over WMSN. 35 However, the energy saving mode was not considered in the standard IEEE 802.15.4. Thus, the proposed system utilizes an asynchronous duty cycle approach to enhance the energy saving mode of the IEEE 802.15.4 which used the preambles' structure mechanism as in X-MAC.…”

Multimedia applications require significantly higher bandwidth than conventional textual applications. Furthermore, multimedia stream requires time sensitive and involves high-energy consumption, which become more challenging on resource constrained networks such as wireless multimedia sensor network (WMSN). As a result, developing an energy efficient algorithm to prolong the network lifetime is the main reoccurring issue in WMSN. Although the duty cycling mechanism has been proven to be an efficient solution for energy saving in various WSN applications, the tradeoff between energy efficiency and quality of service (QoS) on WMSN remains striking. In this article, an adaptive dynamic duty cycle mechanism for energy-efficient medium access control (ADE-MAC) is proposed for WMSNs. ADE-MAC uses a unique asynchronous duty cycle approach to schedule the sleep pattern of each sensor node which can be adapted according to the incoming traffic rate and queuing delay at each node. In the proposed system, the overhead of synchronization is avoided because every node has its own scheduling sleep, and the only sender node must wake up the receiver nodes by using preambles packets. The findings that result from comprehensive simulation show that ADE-MAC outperforms the baseline approaches in term of delivery ratio by 12%, less packet overhead by 28%, less end-to-end delay by 19%, and less power consumption by 41% compared to the baseline mechanisms.

Summary Wireless body area networks (WBANs) dynamically track a person's health data wirelessly. The implant‐to‐implant communication (CM1) inside the human body requires low power, highly reliable channels amidst the high losses and attenuation due to the various portions of the body. This attenuation and noise results in complete variation of the monitored health data, resulting in faulty medical diagnosis and alarms. Low density parity check (LDPC) algorithms are popular for error correction in this scenario. However, they still need to be improved for a more reasonable analysis of the health status. We suggest processing of the sensed data to increase the sparsity, thereby improving the bit error probability performance of the LDPC coding technique. Further, we propose the use of Kalman filter to estimate the actually transmitted bit from the LDPC decoded message output. The simulation results show that the proposed technique improve the error correction capability of the LDPC code. The increased energy, time and computations required for the same is found to be within a satisfactory level for the proper functioning of the WBANs.

“…The strictness in the data latency requirement of WBANs is due to the fact that most medical applications, for example, emergency medical systems, cannot tolerate low response times because if the gathered health data is not delivered in time to a health-care center it may become useless when dealing with emergency situations. However, it is noteworthy that a WBAN system may encounter delay issues in health data communications as a result of interference challenges if the employed communication technologies operate in overcrowded bands [64]. To handle latency in health-care applications, the authors of [65,66] highlighted a few solutions that may be useful in WBAN systems.…”

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.
