Abstract

A silent self-stabilizing asynchronous distributed algorithm, SSLE, is given for the leader election problem in a connected unoriented (bidirectional) network with unique IDs. SSLE also constructs a BFS tree on the network rooted at that leader. SSLE uses O(logn) space per process and stabilizes in O(n) rounds, against the unfair daemon, where n is the number of processes in the network.
