传感器云计算被认为是远程健康监测的关键技术之一。将传感数据集成到传感器云中的云应用程序中，将有助于在地理分布的位置上实时监测患者。在这项研究中，作者研究了最佳网关选择问题的传感器云框架的实时病人监护系统，通过使用零和博弈模型。在该模型中，网关作为第一参与者，根据可用带宽选择策略，而用户请求作为第二参与者，遵循第一参与者选择的策略。作者评估了选择最佳网关的执行时间，通过该网关将感测到的数据获取到云平台。此外，作者还展示了网关如何为用户请求提供服务，以最佳方式访问云平台的数据。作者还表明，通过使用所提出的方法，执行时间减少，从而有助于形成一个可靠，高效和实时的健康监测体系结构。
Sensor-cloud computing is envisioned to be one of the key enabling technologies for remote health monitoring. Integration of sensed data into cloud applications in sensor-cloud will help in real-time monitoring of patients over geographically distributed locations. In this study, the authors study the optimal gateway selection problem in sensor-cloud framework for real-time patient monitoring system by using a zero-sum game model. In the proposed model, a gateway acts as the first player, and chooses the strategy based on the available bandwidth, whereas a user request acts as the second player, and follows the strategy chosen by the first player. The authors evaluate the execution time for selecting the optimal gateway through which the sensed data will be fetched to the cloud platform. In addition, the authors show how user requests are serviced by the gateways to access data from cloud platform optimally. The authors also show that by using the proposed approach, the execution time decreases, thereby helping in forming a reliable, efficient and real-time architecture for health monitoring.
