研究了基于物联网的医疗网络中时延受限的医疗数据包传输调度管理问题。与文献中的大多数现有作品不同，我们专注于超无线体域网（beyond-WBAN）通信，即，智能WBAN网关之间的数据传输（例如，智能手机）和远程医疗中心的基站（BS）。在我们的模型中，各种医疗数据包在每个网关（通常代表一个患者）处随机聚合，并且它们的延迟约束的超WBAN传输请求被立即报告给网络控制器（即，BS），具有反映其医学重要性的不同优先级。BS通过形成处理特定的医疗级服务质量要求（包括医疗分组传输的优先级意识和延迟约束）的调度系统来调度上行链路超WBAN传输。通过考虑物联网网络中智能网关的自然设备智能，我们设计了一种真实有效的机制，可以防止网关从战略上误报医疗数据包的优先级，同时激励BS根据所需的方式管理传输调度。理论和仿真结果验证了该机制的可行性，并证明了其优越性。
In this paper, the scheduling management of delay-constrained medical packet transmissions in Internet of Things (IoT)-based healthcare networks is studied. Unlike most existing works in the literature, we focus on beyond wireless body area network (beyond-WBAN) communications, i.e., data transmissions between smart WBAN-gateways (e.g., smartphones) and the base station (BS) of remote medical centers. In our model, various medical packets are randomly aggregated at each gateway (which ordinarily stands for one patient), and their delay-constrained beyond-WBAN transmission requests are immediately reported to the network controller (i.e., BS) with different priority levels reflecting their medical importance. The BS schedules the uplink beyond-WBAN transmissions by forming a queueing system which addresses specific medical-grade quality of service requirements, including the priority awareness and the delay constraints of medical packet transmissions. By taking into account the natural device intelligence of smart gateways in IoT-based networks, we design a truthful and efficient mechanism which can prevent gateways from strategically misreporting the priority levels of medical packets, while incentivizing the BS to manage the transmission scheduling according to the desired manner. Both theoretical and simulation results examine the feasibility of the proposed mechanism and demonstrate its superiority over the counterparts.
