Integrating Mobile Devices into Semantic Services Environments

This paper addresses mobile service provisioning in a mobile supported sensor network. The challenges of secure service provisioning in such a network is tackled through a two-layer approach, using the encryption on the radio layer and policies for device capabilities and service access. This paper suggests the mobile phone acting as control centre for the sensors. The implementation is based on a distributed semantic service repository, allowing the mobile services to become part of a semantic service composition. The semantic policy server connects the device capabilities, the user preferences and the service functionality. The papers provides the functional architecture and implementations of key elements of this architecture.
