In this paper, we present a leader election protocol in the population protocol model that stabilizes within O(log n) parallel time in expectation with O(log n) states per agent, where n is the number of agents. Given a rough knowledge m of the population size n such that m = log2 n and m=O(log n), this protocol guarantees that exactly one leader is elected and the unique leader is kept forever thereafter.
