An agent-based architecture for wireless bus travel assistants

Multi-agent systems are open and extensible systems that allow for
the deployment of autonomous and proactive software components. This paper
describes how a multi-agent architecture has been developed to extend a
previously implemented bus travel assistant prototype called Bus Catcher [2].
Such a system was developed to provide accurate information about bus
locations and arrival times to Dublin Bus users. The new version of the system
is more flexible and easily extensible as it relies on generic agents responsible
for channeling context sensitive services. New features have also been added to
the system, including user profiling and monitoring of available
hardware/service characteristics
