Exploring spatial relationships and identifying influential nodes in cellular networks
Optional Fields
CDR Cellular networks Network dynamics Resource usage Spatial usage
This work provides an up to date measurement-driven examination of the spatial characteristics of network resource usage. The data set used is from a large nationwide 3G cellular network comprised of several thousand base stations. Firstly, we discuss our data set and its potential application. Next, we examine the spatial correlation between base stations in terms of radio resource usage. We find significant spatial correlation, particularly for proximate base stations. We examine the causality structure in the network using Granger causality to identify key influential indicator base stations within sub-networks. These indicator base stations act as hubs in the wider network and provide additional information about the future states of their neighbors. The penultimate section examines the influential indicator base stations in more detail. Finally, we conclude with a brief discussion of the key points and how we aim to progress this work.
