Approximate counting:a martingale approach

Pages 111-120 | Accepted 30 Jul 1986, Published online: 04 Apr 2007
 

Abstract

Approximate counting is a probabilistic algorithm for keeping track of large numbers of events by means of a counter of limited range. In this paper we present an analysis of this algorithm using the elementary theory of martingales. The methods are also applicable to the analysis of the counter which occurs in the exponential back off protocol
