As mobile agents reside on on-board units or mobile devices and act on behalf of drivers, it imposes a strong demand to devise mechanisms for protecting the algorithms that are exclusively coded in mobile agents for different drivers. Although contactless smart cards are widely used as a means to protecting personal information, it is still a challenge to protect the whole code of a mobile agent in...
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...
Web service technologies are best exploited by composing services, and BPEL (Web Services Business Process Execution Language) is adopted industrial-wide as the defacto service composition standard. However, BPEL is applied mainly in the design of composite services and fully automated processes, and user interaction, that should be included in service delivery, but presently is not included in the...
As the number of agents increases rapidly on the Internet, discovering appropriate service agents with required capabilities for request agents becomes a crucial issue in multi-agent systems. Two major discovering approaches have been developed: centralized matchmaking approaches and distributed bidding approaches. However, the former approaches may suffer the problem of middle agent overload and...
