Transmission Management of Delay-Sensitive Medical Packets in Beyond Wireless Body Area Networks: A Queueing Game Approach

In this paper, the management of delay-sensitive medical packet transmissions in beyond wireless body area networks (beyond-WBANs) is studied. The considered system addresses the random arrival of sensed medical packets at each WBAN-gateway, which are categorized into different classes (one class of emergent alarms and multiple classes of non-emergent routines). Upon receiving a medical packet, the associated gateway immediately declares a beyond-WBAN transmission request to the base station (BS). With the consideration of medical-grade quality of service (mQoS) requirements, the beyond-WBAN transmissions of heterogeneous packets are scheduled by following the constructed queueing models with specifically designed priority disciplines. By further considering the potential strategic behaviors of smart gateways, a non-cooperative delay-dependent prioritized queueing game for the beyond-WBAN transmission management is formulated. After that, we propose a novel analytical framework to jointly characterize the queueing performance and the properties of the game equilibrium. Theoretical and simulation results justify the feasibility and applicability of our designed transmission management system in beyond-WBANs.
