“…A number of MAC protocols have been researched and proposed for HMA, and most of these protocols are based on IEEE 802.15.4. Among these proposed protocols, the majority are focused on saving energy [13][14][15][16], while some are focused on QoS provisions [17][18][19][20][21][22][23][24]. Very few studies deal with the subject of emergency handling [23,24].…”

The recent advances in wireless communication systems and semiconductor technologies are paving the way for new applications over wireless sensor networks. Health-monitoring application (HMA) is one such emerging technology that is focused on sensing and reporting human vital signs through the communication network comprising sensor devices in the vicinity of the human body. The sensed vital signs can be divided into two categories based on the importance and the frequency of occurrence: occasional emergency signs and regular normal signs. The occasional emergency signs are critical, so they have to be delivered by the specified deadlines, whereas the regular normal signs are non-critical and are only required to be delivered with best effort. Handling the occasional emergency sign is one of the most important attributes in HMA because a human life may depend on correct handling of the situation. That is why the underlying network protocol suite for HMA should ensure that the emergency signs will be reported in a timely manner. However, HMA based on IEEE 802.15.4 might not be able to do so owing to the lack of an appropriate emergency-handling mechanism. Hence, in this paper, we propose a new emergency-handling mechanism to reduce the emergency reporting delay in IEEE 802.15.4 through the modified superframe structure. A fraction of an inactive period is modified into three new periods called the emergency reporting period, emergency beacon period, and emergency transmission period, which are used opportunistically only for immediate emergency reporting and reliable data transmission. Extensive simulation is performed to evaluate the performance of the proposed scheme. The results reveal that the proposed scheme achieves improved latency and higher emergency packets delivery ratio compared with the conventional IEEE 802.15.4 MAC.

“…Khaled et al have classified traffic into two groups: critical and non-critical [19]. However, their study is mainly concentrated on determining the number of retransmissions based on traffic criticality, i.e., providing the maximum number of retransmissions to critical traffic, and avoids other QoS issues.…”

Since traffics of class1 are not allowed the CFP of class2 and vice-versa, delay Khaled et al [13] has classified traffic based on critical and non-critical issues.

Wireless Body Area Network (WBAN) is a special purpose personal area network with health-care and other value-added applications. Recently, patient monitoring applications using WBAN have received significant attention. Patient monitoring applications are intended to report any sign of emergency in the monitored patient to the corresponding health personal so that necessary actions can be taken before it is too late. Therefore, the underlying protocol suite in WBAN should ensure that the emergency events will be timely reported. However, WBAN based on IEEE 802.15.4 might not be able to do so. Hence, in this paper, we devise the emergency handling capability in IEEE 802.15.4 MAC. We propose a modified superframe structure for supporting immediate emergency reporting and reliable data transmission. A fraction of inactive period is used opportunistically for three new periods in such a way that temporary switching between the new periods and inactive period occurs only for handling emergency events. We also suggest two different random channel access mechanisms for reporting emergencies. Through the numerical results, we show that the proposed scheme achieves improved latency and throughput in the WBAN environment with compare to IEEE 802.15.4.

“…Although their work introduced the concept of diverse periods for diverse traffic classes, the classification was based only on the periodicity of the traffic instead of on diverse QoS demands. Khaled et al [19] also classified traffic based on critical and non-critical issues. However, their work mainly concentrated on determining the number of retransmissions based on traffic criticality and avoided the other QoS issues.…”

The emergence of heterogeneous applications with diverse requirements for resource-constrained Wireless Body Area Networks (WBANs) poses significant challenges for provisioning Quality of Service (QoS) with multi-constraints (delay and reliability) while preserving energy efficiency. To address such challenges, this paper proposes McMAC, a MAC protocol with multi-constrained QoS provisioning for diverse traffic classes in WBANs. McMAC classifies traffic based on their multi-constrained QoS demands and introduces a novel superframe structure based on the “transmit-whenever-appropriate” principle, which allows diverse periods for diverse traffic classes according to their respective QoS requirements. Furthermore, a novel emergency packet handling mechanism is proposed to ensure packet delivery with the least possible delay and the highest reliability. McMAC is also modeled analytically, and extensive simulations were performed to evaluate its performance. The results reveal that McMAC achieves the desired delay and reliability guarantee according to the requirements of a particular traffic class while achieving energy efficiency.
