CoSeMed - cooperative and secure medical device cloud

In order to properly support patient treatment, e-health systems need to dynamically integrate heterogeneous types of medical sensors and provide access to streams of sensed medical data independent of the patients location or the movement of the respective medical devices. Treatment processes usually include several steps and medical departments, which means that sensors have to be moved between networks of different operators. The common style of vital sign monitoring basically relies on reintegrating new sensors belonging to one operator each time a patient is moved between them. Therefore we propose a novel approach, that allows to share medical devices among different operators. This means that each operator just books a medical device as long as it delivers required data and is present in the operators network, which we call the medical device cloud. Additionally an aggregation middleware that dynamically integrates medical devices by reloading device drivers and required data utilization modules is presented.
