With Mobile Ad hoc Networks (MANETs), communication between mobile users is possible without any infrastructure. MANETs are already a necessary part of wireless systems. Due to arbitrary node arrivals, departures, crashes and movements, network partitioning may arise resulting in a degradation of the service, but not necessarily in its interruption. In this paper, we propose a distributed system model for partition able systems. We then specify and implement a partition-participant detector that captures the live ness of a partition even if the partition is not completely stable. Its role is to detect the minimal stability condition to guarantee that eventually all the stable processes in an alpha-Set elect the same leader.
