摘要
En 中文
Mobile ad hoc networks as well as grid platforms are distributed, changing, and error prone environments. Communication costs within such infrastructure can be improved, or at least bounded, by using k-clustering. A k-clustering of a graph, is a partition of the nodes into disjoint sets, called clusters, in which every node is distance at most k from a designated node in its cluster, called the clusterhead. A self-stabilizing asynchronous distributed algorithm is given for constructing a k-clustering of a connected network of processes with unique IDs and weighted edges. The algorithm is comparison based, takes O(nk) time, and uses O(log n + log k) space per process, where n is the size of the network. To the best of our knowledge, this is the first solution to the k-clustering problem on weighted graphs. (c) 2010 Elsevier Inc. All rights reserved.
