It is now well recognised that the consensus problem is a fundamental problem when one has to implement fault-tolerant distributed services. In this paper, we extend the consensus paradigm to asynchronous distributed mobile systems prone to disconnection and process crash failures. The paper, first, shows that a consensus problem between mobile hosts is reducible to two agreement problems (a consensus problem and a group membership problem) between fixed hosts. Then, following an approach investigated by Guerraoui and Schiper, the paper uses a generic consensus service as a basic building block to construct a modular and simple solution.
