Abstract This paper presents a fast distributed algorithm to find a small fe-dominating set in a graph G , with n nodes and m edges, n > k + 1. A k -dominating set D of G is a set of nodes such that for every node υ of G , there exists a node of D whose distance to υ is at most k. D is said to be a small k -dominating set if it has at most [ n/k +1] nodes, which is the best lower bound for the size of D in general. The algorithm is synchronous, its time complexity is O ( k log ∗ n ) and its message complexity is O ( n log k log ∗ n ). Small k -dominating sets have applications in a number of areas, including the design of distributed data structures, the selection of servers in a network, and routing with sparse tables. Note, finally, that the decision problem related to finding the smallest k -dominating set of G is NP-Complete. |
