Queueing analysis for medical data transmissions with delay-dependent packet priorities in WBANs

In this paper, we propose a queueing model for analyzing performances of prioritized data transmissions in Medical Wireless Body Area Networks (mWBANs). Unlike the existing works, we consider the medical packet priority jointly with the delay-dependent dynamic priority in transmission scheduling at sensor nodes. The interaction between priority queues and instantaneous delay limits make the analysis much more complicated. Based on the transient queueing analysis, we develop a buffer-overflowing queueing principle to approximate the over-deadline queueing principle in this prioritized transmission scheduling system. Numerical and simulation results show that the proposed approximation queueing model works as a good fit to this prioritized data transmission system in mWBANs, and the proposed delay-dependent falling priority principle makes medical packets' transmission more reasonable in terms of timeliness issues.
