In this paper we discuss the analysis of mobile networks communication patterns in the presence of some anomalous “real world event”. We argue that given limited analysis resources (namely, limited number of network edges we can analyze), it is best to select edges that are located around ‘hubs’ in the network, resulting in an improved ability to detect such events. We demonstrate this method using a dataset containing the call log data of 3 years from a major mobile carrier in a developed European nation.
