An Optimal Termination Detection Algorithm for Murat Demirbas Anish Arora 1

Summary: An Optimal Termination Detection Algorithm for

This paper presents an optimal termination detection algorithm for rings. The
algorithm is based on Safra's and Dijkstra et al.'s [1] algorithm. It optimizes the
time constant of the Dijkstra & Safra algorithm from 2N 3N to 0 N , where N
denotes the number of processes in the ring. A proof of correctness of the algorithm
is also presented.
Keywords : Termination detection, Distributed computing, Algorithms.
