“…On the other hand, IEEE 802.15.4 attracted many researchers due to its quick implementation and support of low data rate applications with low cost of power consumption. C. Li et al studied the performance of both beacon and non-beacon modes of IEEE 802.15.4 MAC protocol and concluded that the non-beacon mode transcends the beacon mode in terms of throughput and latency but with high cost of power consumption [8]. Similarly, Timmons et al supported the non-beacon mode for low data rate and asymmetric traffic [9].…”

Wireless Body Area Network (WBAN) consists of low-power, miniaturized, and autonomous wireless sensor nodes that enable physicians to remotely monitor vital signs of patients and provide real-time feedback with medical diagnosis and consultations. It is the most reliable and cheaper way to take care of patients suffering from chronic diseases such as asthma, diabetes and cardiovascular diseases. Some of the most important attributes of WBAN is low-power consumption and delay. This can be achieved by introducing flexible duty cycling techniques on the energy constraint sensor nodes. Stated otherwise, low duty cycle nodes should not receive frequent synchronization and control packets if they have no data to send/receive. In this paper, we introduce a Traffic-adaptive MAC protocol (TaMAC) by taking into account the traffic information of the sensor nodes. The protocol dynamically adjusts the duty cycle of the sensor nodes according to their traffic-patterns, thus solving the idle listening and overhearing problems. The traffic-patterns of all sensor nodes are organized and maintained by the coordinator. The TaMAC protocol is supported by a wakeup radio that is used to accommodate emergency and on-demand events in a reliable manner. The wakeup radio uses a separate control channel along with the data channel and therefore it has considerably low power consumption requirements. Analytical expressions are derived to analyze and compare the performance of the TaMAC protocol with the well-known beacon-enabled IEEE 802.15.4 MAC, WiseMAC, and SMAC protocols. The analytical derivations are further validated by simulation results. It is shown that the TaMAC protocol outperforms all other protocols in terms of power consumption and delay.

“…During the CAP period, devices contend for channel access using slotted CSMA-CA. It has been found that IEEE 802.15.4 does not meet all the energy efficiency requirements for WBAN applications [52][53][54]. It is because of these shortcomings that the IEEE 802.15 Task Group 6 (Wireless Body Area Networks) began developing a communication standard optimized for low power devices that operate on, in or around the human body (but not limited to humans) to serve a variety of applications including medical, consumer electronics / personal entertainment and others [32].…”

Abstract. Wireless body area networks (WBANs) are emerging as important networks, applicable in various fields. In this chapter a comprehensive survey of WBANs that are designed for applications in healthcare is presented. The survey consists of stand-alone sections focusing on important aspects of WBANs. Topics covered are: monitoring and sensing, power efficient protocols, physical layer, MAC protocols, routing, system architectures and security. The chapter concludes with a discussion of open research issues, their potential solutions and future trends.

“…Many researchers focused on the use of IEEE 802.15.4 and IEEE 802.15.1 [5], however, the latter is not widely adapted due to its complexity and high power consumption. The IEEE 802.15.4, on the other hand, has been extensively studied because of immediate implementation and low-power consumption [6]- [7]. One of the drawbacks of IEEE 802.15.4 is periodic beacon listening, which is not suitable for WBAN due to low duty cycle nodes that may sleep for hours and may not require periodic beaconing.…”

One of key attributes of WBAN is to extend the network lifetime, which can be achieved by adjusting the wakeup and sleep modes of the sensor nodes. Traditional low-power methods such as channel polling and periodic duty cycling are unable to satisfy WBANs requirements due to idle listening, collision, and control packet overhead problems. In this paper, we propose an RFID-enabled MAC protocol (RMAC) for WBAN that dynamically adjusts the wakeup and sleep modes of the nodes according to the traffic, thus solving the idle listening and overhearing problems. The protocol accommodates normal and emergency traffic using pre-scheduled and RFID wakeup methods. Analytical expressions are derived to analyze the power consumption and delay of the proposed protocol for normal and emergency traffic. The analytical expressions are further validated by extensive simulations using Network Simulator 2(NS2).
