Disconnected components detection and rooted shortest-path tree maintenance in networks
International audienceMany articles deal with the problem of maintaining a rooted shortest-path tree. However, after some edge deletions, some nodes can be disconnected from the connected component of some distinguished node . In this case, an additional objective is to ensure the detection of the disconnection by the nodes that no longer belong to . We present a detailed analysis of a silent self-stabilizing algorithm. We prove that it solves this more demanding task in anonymous weighted networks with the following additional strong properties: it runs without any knowledge on the network and under the \emph{unfair} daemon, that is without any assumption on the asynchronous model. Moreover, it terminates in less than rounds for a network of nodes and hop-diameter
