... this comes frequently with an added complexity and energy consumption. Table 2 shows the general differences between ANT, BLE, IEEE 802.15.4 and the newly defined IEEE 802.15.6 whereas Table 3 summarises the types of applications each mechanism is designed for. As our study shows, it is notable that 802.15.6 is a very flexible standard especially regarding the variety of data rates and its MAC layer mechanisms. ...

The evolution of wireless body area network (WBAN) has changed the human life for its applications in the field of healthcare, fitness, entertainment and sports etc. However, two of the major challenges in the design of WBAN are energy efficiency and guaranteeing QoS. The load balance of different packet queues in a WBAN plays important role in design of energy efficient and reliable system. In this paper, we propose a Traffic Prioritized Load Balanced Scheduling (TPLBS) algorithm for load balancing in different priority queues in wireless body area networks based on IEEE 802.15.6 model. The main objective of this paper is to minimize packet drop in the queues so that throughput of WBAN can be improved. In this case we consider both priority and location from which the packet received, so that no packet should wait for a long time in the assigned queue to be transmitted to Access Point. The proposed method is simulated using Castalia to study and compare its performance with its counterparts. The simulation results reveal that the proposed protocol works better than the existing methods in terms of delay, throughput and energy efficiency.
... The hub transfers then the received data to a wider-ranging external network for an eventual medical diagnostic [4] . A variety of existing wireless communication standards have been used for WBANs such as ANT [5] , BLE [6] and IEEE 802.15.4 [7] until IEEE 802.15.6 [8] has been specifically designed for WBANs [9] . IEEE 802.15.6 is distinguished from other standards by a wide variety of highly flexible features such as the support of service differentiation, short range (the vicinity of human body), various frequency bands, support of high data rates, low power consump-tion, various access modes, periods and methods, etc [4,9,10] . ...

eHealth applications have become essential in everyday life healthcare especially for elderly and sick individuals. To provide efficiency to such applications, many standards emerged for WBANs. However, WBANs standards showed their limits in terms of QoS and priorities differentiation depending on applications need. In this paper, we investigate IEEE 802.15.6 MAC performance efficiency and we define TA-802.15.6, an enhanced IEEE 802.15.6 CSMA/CA channel access mechanism. We aim to differentiate all IEEE 802.15.6 priorities traffics and to improve IEEE 802.15.6 based networks performances. Our main contribution is the enhancement of IEEE 802.15.6 CSMA/CA retransmission and packet drop processes. We also defined a new algorithm for dynamic backoff bounds assignment according to IEEE 802.15.6 priorities and to the network traffic state. We make an analytical evaluation through a new 4D Markov chain and by simulation based on Castalia. Results validate that the enhanced IEEE 802.15.6 CSMA/CA version provides a better service differentiation through accentuating priority differentiation and a better QoS in terms of reliability, throughput and energy consumption.
