Objects are reactive in the sense that they change state only when one of their methods is invoked by other objects. Reactive objects are sufficient in a client-server model of computation with a remote invocation mechanism ``{\`a la RPC\/}''. However, active objects are much more powerful mainly because they are autonomous entities. \Epidaure's objects are a particular type of active objects from which multi-agent systems can be built. In the context of mobility, migration becomes a necessity. For instance, a mobile client may disconnect from its server and reconnect to another server at a later time. In this paper, we describe in a detailed manner the communication mechanism of a particular multi-agent system, \Epidaure, and how the communication algorithm and mobility protocols that we developed can be applied to address problems related to mobile objects e.g., registration, transport, tracking, etc.).
