A core of a graph G = (V, E) is a path P in G which minimizes d(P)=∑ v∈V d(v, P) where d(v,P) is the distance of vertex v from P. Finding a core of a network is essential in locating the best sites to set up service facilities. Here we present the first distributed algorithm which finds a core of a tree network in O(D) time using O(n) messages, where D and n are the diameter and the number of vertices of G respectively.
