Abstract

We consider the problem of leader election in asynchronous oriented N-node complete networks. We present a leader election algorithm with O(N) message and O(log logN) time complexity. The message complexity is optimal and the time complexity is the best possible under the assumption of message optimality. The best previous leader election algorithm for asynchronous oriented complete networks by Singh [16] achieves O(N) message and O(logN) time complexity.
