In many applications we are required to increase the deployment of a distributed monitoring system on an evolving network. In this paper we present a new method for finding candidate locations for additional deployment in the network. This method is based on the Group Betweenness Centrality (GBC) measure that is used to estimate the influence of a group of(More)
—We propose and evaluate two complementary heuristics to speed up exact computation of the shortest-path betweenness centrality. Both heuristics are relatively simple adaptations of the standard algorithm for betweenness centrality. Consequently, they generalize the computation of edge between-ness and most other variants, and can be used to further speed(More)
Modern business activities rely on extensive email exchange. Email " wrong recipients " mistakes have become widespread, and the severe damage caused by such mistakes constitutes a disturbing problem both for organizations and for individuals. Various solutions attempt to analyze email exchange for preventing emails to be sent to wrong recipients. However(More)
—OpenFlow is a protocol-implementing Software Defined Networking, a new networking paradigm, which segregates packet forwarding and accounting from the routing decisions and advanced protocols. This segregation increases agility and flexibility and reduces operational expenses of the networking infrastructure. Despite the apparent benefits, many companies(More)
