Recently, the Internet of Things (IoT) topology has used to collect physical, physiological, vital signs of patients in consumer-centric e-health or consumer’ wellness care services. In such healthcare systems, varieties of medical sensors are attached to the patients to collect vital signs from those who are under observation. The data gathering process in IoT-enabled Wireless Sensor Network (WSN) suffers from the congestion problem. The effect of this translates on missing packets, a decrease of reliability and throughput degradation in IoT-enabled WSN. This article proposes a distributed congestion control algorithm for IoT-enabled WSNs to effectively resolve the congestion for healthcare applications. The proposed scheme alleviates congestion by a priority-based data routing strategy. Furthermore, this article presents a priority queue based scheduling scheme for better reliability. We analyze the properties of the proposed congestion control mechanism mathematically and validate its performance through extensive simulation and real-life experiments. The application of this work can be used to an early warning system in detecting abnormal heart rate, blood pressure, ECG, EMG in the hospital/home care environment to the state-of-art diagnosis.

用于智能医疗保健应用的支持物联网的无线传感器网络的无拥塞路由机制

最近,物联网 (IoT) 拓扑已用于在以消费者为中心的电子健康或消费者的健康护理服务中收集患者的身体、生理、生命体征。在这样的医疗保健系统中,各种医疗传感器被连接到患者身上,以收集被观察者的生命体征。支持物联网的无线传感器网络 (WSN) 中的数据收集过程存在拥塞问题。这会转化为丢失数据包、可靠性降低和支持物联网的 WSN 的吞吐量下降。本文为支持物联网的 WSN 提出了一种分布式拥塞控制算法,以有效解决医疗保健应用的拥塞问题。所提出的方案通过基于优先级的数据路由策略来缓解拥塞。此外,本文提出了一种基于优先级队列的调度方案,以获得更好的可靠性。我们从数学上分析了所提出的拥塞控制机制的特性,并通过广泛的模拟和现实生活实验验证了其性能。这项工作的应用可用于早期预警系统,在医院/家庭护理环境中检测异常心率、血压、心电图、肌电图以进行最先进的诊断。
