Abstract

We consider the task of electing a leader in a distributed manner in ad hoc multi-hop radio networks. Radio networks represent the class of wireless networks in which one frequency is used for transmissions, network's topology can be represented by a simple undirected graph with some n nodes, and there is no collision detection. We give a randomized algorithm electing a leader in O(n) expected time and prove that this time bound is optimal. We give a deterministic algorithm electing a leader in O(n log3/2 n √log log n) time. By way of application, we show how to perform gossiping with combined messages in O(n log3/2 n√log log n) time by a deterministic algorithm, and in O(n) expected time by a randomized algorithm.
