In this paper, we study distributed algorithms for finding the k-th
value in the decentralized systems. First we consider the case of
circular configuration of processors where no processor knows the total
number of participants. Later a network of arbitrary configuration is
examined and a tree-based algorithm is proposed. The proposed algorithm
requires O(N) messages and O(log N) rounds of message passing, where N
is the number of nodes in the network.
