We introduce and study a process algebra able to model the systems composed of processes (agents) which may migrate within a distributed environment comprising a number of distinct locations. Two processes may communicate if they are present in the same location and, in addition, they have appropriate access permissions to communicate over a channel. Access permissions are dynamic, and processe...
