Ubiquitous Mobile Awareness from Sensor Networks

• Users require applications and services to be available everywhere,enabling them to focus on what is important to them. Therefore, contextinformation (e.g., spatial data, user preferences, available connectivity anddevices, etc.) has to be accessible to applications that run in end systems closeto users. In response to this, we present a novel architecture for ubiquitoussensing and sharing of context in mobile services and applications. Thearchitecture offers distributed storage of context derived from sensor networkswirelessly attached to mobile phones and other devices. The architecture alsohandles frequent updates of sensor information and is interoperable withpresence in 3G mobile systems, thus enabling ubiquitous sensing applications.We demonstrate these concepts and the principle operation in a sampleubiquitous Mobile Awareness service.
