Distributed k-core Decomposition of Dynamic Graphs

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. In this poster, 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.
