This paper considers sensor networks for intrusion detection, such that node deployment, node failures and node behavior result in coverage gaps and a fraction of disconnected nodes in an otherwise dense and well-connected network. They focus on the time delay for a mobile intruder to be detected by a sensor with a connected path to the sink, in contrast to existing results for the detection time by a sensor with arbitrary connectivity. They model their network using a supercritical percolation model on the plane, implying the existence of a unique unbounded connected component, and they assume that the sink belongs to this component.
