Context-Aware Processing of Mobile Device Sensor Information: Car Accident Detection Hosted Service

Context-aware applications can be made globally deployed through hosted applications that can process contextual information captured by the sensors available at the personal devices surrounding the user. In the first part of this paper the architectural principles to deploy contextual applications from the operator network are presented, focusing on the current state-of-the-art technological options for convergence. In order to demonstrate the principles introduced, a prototype is developed of a contextual service to detect pervasively the driving emergencies of the user and trigger the appropriate actions from the network, including an emulator of the device terminal capabilities, convergent control layer and context-aware application server. The description and specific details of such prototype are provided in the second part of the paper.
