The LISA prototype framework for media access and delivery

This paper presents the LISA (location independent service agents) prototype framework for location independent media service access and delivery. Location independent media services imply that a user can be nomadic and be delivered media services at any location via the network. The delivery of media using mobile agent technology enhances the access and delivery of media services by evaluating the media and network context. To enable these enhancements, mobile agents must traverse networks to discover and deliver media services to nomadic users. The LISA prototype uses mobile agents that cooperate to traverse networks, find media, determine media context, and provide media services. This paper addresses two sources of contextual information within this paradigm, the contextual nature of the network path and the current context of multiple sources of media storage.
