Abstract
IOT (Internet of Thing) rapid rise in recently years. It can be taken as one of the most influential technology in the future. It is a computational concept through the connection between physical object and Internet to realize intelligent identification and management. It has been widely used including transportation management, medical healthcare, driverless car and intelligent appliances. In this thesis, we use the technology in combination with wearable device and cloud computing, and im- plement an IOT application service which can monitor and analyze the health state of patient in real-time. We also discuss the problem of dynamic resource manage- ment in distributed stream computing system. Our system can adjust the resources according to the loading of computation from users to promote the cost-effectiveness and guarantee the performance simultaneously.
