TItle: Physicians and Patients, Mobile Interaction and Monitoring system

Description: In this paper, we present the implementation of a remote monitoring and interaction system for medical applications. Recent advances in medical platforms have focused mainly on continuous and constant remote monitoring of a patient. Compared to existing solutions, our system has placed emphasis on remote interaction between a patient and a physician. We provide in this system capabilities to perform diagnosis and treatment over-the-air. Such system is valuable for instant response to emergency health alerts. Today, this emergency process of monitoring and feedback actuation is done by a self-contained device (such as an implantable cardioverter-defibrillator), which provides treatment automatically when detecting abnormalities. We believe that it is very important to involve the physician in this process of actuated treatment. We accomplish this goal by virtually connecting a patient and a physician anytime anywhere. We propose a mixed twoand three- tier infrastructure that extends current three-tier architecture with a GSM/GPRS peer-to-peer channel. We present a working system that is built on top of commercial cellular phones and wireless sensor nodes. In our system, a physician can create and subscribe to ”interests” provided by a body sensor network deployed on a patient. An interest is defined as the useful information acquired from applying a series of computations to collected vital signals. Profiles of interests can be periodically delivered in the form of health status reports, or they can be used to trigger emergency health alerts immediately when abnormalities are detected. The advanced interactive capabilities of our system allow a remote physician to further query for detailed information, to create and subscribe to new interests, to set sensor parameters, and to trigger actuators for over-the-air treatment. Additionally, we introduce a concept of multi-resolution to help a physician identify useful information from a huge amount of sensor data collected by the body sensor network on a patient and hence to reduce communication costs. This paper describes why our proposed infrastructure suits novel medical scenarios and outlines the design and implementation of our system.
