An extensible and interactive software agent for mobile devices based on GPS data

This paper presents a real-time software agent for monitoring and supporting users that move along predefined paths. We investigated appropriate models for geographical data and communications (based on cellular networks), also an ad-hoc localization algorithm based on GPS technologies has been implemented. We developed an Interactive Road System by installing the whole application on a mobile device and we customized it for supporting drivers. The power of the system is based on its flexibility and the possibility to extend the set of action, the agent has to perform.
