“…The MAC layer can reduce the energy consumption of sensors using the reduced duty cycle. Therefore, the cross-layer based on this study [61] proposes Controllable Phase Locked Loop (CPLL) and CPLL automatic repeat request (P-ARQ) method. The CPLL adds a Frequency Compensation (FC) module which can reduce the state transition from the sleep state to Tx/Rx state.…”

“…The FC module is connected with the Voltage Controller Oscillator (VCO) module for setting up frequency of a sensor. Moreover, the P-ARQ [61] uses three-way handshakes to establish the connection between a slave sensor and master sensor in the network initialization phase. The MAC header uses PPL Lock and PPL Count to lock the connection and count the number of transmitted/received frames.…”

“…The PDR of [59] is lower as compared to [54,56,58]. The P-ARQ [61] does not consider the patient data but the energy consumption of this protocol [61] is lower as compared to [54,59] and is outperformed as shown in [56]. The CL-JS [44] provides data reliability in terms of retransmission of frames.…”

“…The energy consumption of [65] is higher as experienced in [4,43,44,54,59]. However, [43,55,56,58,61] are having lower energy consumption as compared to [65]. The work in [65] classifies patient data into four classes also as discussed in [43].…”

In Wireless Body Area Network (WBAN), various biomedical sensors (BMSs) are deployed to monitor various vital signs of a patient for detecting the abnormality of the vital signs. These BMSs inform the medical staff in advance before the patient’s life goes into a threatening situation. In WBAN, routing layer has the same challenges as generally seen in WSN, but the unique requirements of WBANs need to be addressed by the novel routing mechanisms quite differently from the routing mechanism in Wireless Sensor Networks (WSNs). The slots allocation to emergency and nonemergency patient’s data is one of the challenging issues in IEEE 802.15.4 and IEEE 802.15.6 MAC Superframe structures. In the similar way, IEEE 802.15.4 and IEEE 802.15.6 PHY layers have also unique constraints to modulate the various vital signs of patient data into continuous and discrete forms. Numerous research contributions have been made for addressing these issues of the aforementioned three layers in WBAN. Therefore, this paper presents a cross-layer design structure of WBAN with various issues and challenges. Moreover, it also presents a detail review of the existing cross-layer protocols in the WBAN domain by discussing their strengths and weaknesses.
