A QoS based comparative analysis of the IEEE standards 802.15.4 & 802.15.6 in WBAN-based healthcare monitoring systems

In the current paper, we present a comparative analysis of the wireless standards IEEE 802.15.4 and IEEE 802.15.6 over a WBAN healthcare monitoring system based on the MAC sub-layer. The main consideration of this work is to look for determined factors to decide about the norm providing the optimal quality of service (QoS) for such system in normal traffic conditions. For this purpose, a comprehensive set of simulations has been conducted using Castalia Simulator to evaluate the average latency, throughput and reliability of the two standards under the same conditions.
