Abstract

The problem of electing a leader in a dynamic ring in which processors are permitted tofail and recover during election is discussed. It is shown that theta (n log n+k/sub r/)messages, counting only messages sent by functional processors, are necessary andsufficient for dynamic ring election, where k/sub r/ is the number of processor recoveriesexperienced.
