针对新一代健康监护系统在综合运用传感器网络、云计算和大数据等技术时存在的移动性、网络延迟、慢性疾病预测的准确率局限性问题,设计了一种基于云雾辅助的移动健康监护系统.通过分析基于云雾辅助的移动健康监护系统的层次化结构,解决了该系统的3项关键技术,包括:采用基于IPv6的网络体系结构以增加移动性,采用基于时间阈值的云雾资源统一调度算法以降低响应延迟,采用基于级联特征降维和特征选择的慢性病变风险分级模型以提高预测的智能性和准确率.对比实验表明,该系统具有更低的响应延迟和更高的慢性病变风险分级准确率,从而有利于心血管病类慢性疾病的早期预警.

The new generation healthcare monitoring system integrates sensor networks,cloud computing and bigdata technologies,and there are still limitations in mobility,network delay,and the accuracy of chronic disease prediction.In response to the above situation,a cloud & fog-assisted mobile health monitoring system was designed.First of all,the hierarchy structure of cloud & fog-assisted mobile health monitoring system is analyzed.Then,some key technologies of the system are solved as follows:designing IPv6-based network architecture to enhance mobility; adopting unified scheduling algorithm of cloud & fog resources based on time threshold to reduce response delay; relying on risk classification model of chronic diseases based on a cascade feature dimensionality reduction and feature selection to improve the intelligence and accuracy of chronic lesions prediction.Finally,the comparative experiments demonstrate that the system has lower response delay and higher accuracy of chronic disease risk classification,which is conducive to early warning of chronic cardiovascular disease.
