Distributed k-core decomposition of dynamic graphs
Paul Jakma, Marcin Orczyk, Colin S. Perkins, Marwan M. Fayed · 2012
The k-core decomposition can be used to reveal structure in a graph. It is straight-forward to implement using a centralised algorithm with complete knowledge of the graph, but no distributed k-core decomposition algorithm has been published. We present a continuous, distributed, k-core decomposition algorithm for dynamic graphs, outline a proof of correctness, and give initial performance results. We briefly describe an application of this distributed k-core algorithm to landmark selection for compact routing.
