Delivery of telematics services using OSGi and mobile agents

Delivering distributed telematics services has gained increasing attention in mobile computing and advanced traveler information fields. In this paper, to design and implement telematics applications, OSGi technology is exploited to support interoperability of various telematics services. Moreover, we propose a mobile agent approach to enabling the delivery of distributed OSGi services, which can gain better performance when applying it to mobile devices with limited resources and unstable connections. An application of telematics services, which assists drivers in reporting accident events when accident occurs and warns them of traffic accidents or jams on their planned routes is developed. In this application, OSGi is adopted as a service platform to manage services provided by diverse devices, while mobile agents are employed to migrate across multiple devices to access required services.
