Failure, Disconnection and Partition Detection in Mobile Environment


In mobile environment, nodes can move around and voluntarily leave or join the network. Furthermore, they can crash or be disconnected from the network due to the absence of network signals. Therefore, failure, disconnection and mobility may create partitions in wireless networks which should be detected for fault and disconnection tolerance reasons. We present in this article an architecture of local and distributed detectors for mobile networks that detect failures, disconnections, and partitions. It is basically composed of three unreliable detectors: a heartbeat failure detector, a vector-based disconnection detector, and an eventually perfect partition detector. The latter ensures the convergence of detection information within a partition where all participants suspect the same sets of disconnected, unreachable, and faulty processes.
