Wireless networks often experience a significant amount of churn, the arrival and departure of nodes. We propose a distributed algorithm that detects churn and is resilient to a worst-case adversary. The nodes of the network are notified about changes quickly, in asymptotically optimal time up to an additive logarithmic overhead.
