When designing distributed object-based systems one is often faced with the problem of modelling the movement of objects from site to site in a distributed network. In order to model such an activity, some supervising or coordination mechanisms are needed, to insure correctness of both movement and communication in the network. In this paper we propose distributed object-based action systems as a basis for (coordinated) mobile computing. In order to model mobility and coordination we extend the action systems and OO-action systems formalisms with so called mobile objects and coordinator objects. The mobile objects move in some domain whereas the coordinator objects control the actions of the mobile objects within their respective domains. We show the applicability of the proposed framework with a small though nontrivial example.
