Semantic Enrichment of Mobile and WiFi Network Data

Abstract

This chapter comprises the main contribution of this thesis and sheds light on the process of semantically enriching mobile and WiFi network data. As a result of this process, it introduces the OpenMobileNetwork, which is an open platform for providing approximated and semantically enriched mobile network and WiFi access point topology data based on the principles of Linked Data. Network measurements that are constantly collected via crowdsourcing are used to infer the topology of mobile networks and WiFi access points worldwide. The created dataset is further interlinked with other datasets in the LOD Cloud (e.g., LinkedGeoData or Linked Crowdsourced Data) for providing additional context information that is geographically and semantically related to the network topology data such as POIs covered by the reception areas of the mobile network cells. It is made available to the public through a SPARQL endpoint and described using VoID. With the update of the diagram in August 2014 (see Fig. 4.1), the OpenMobileNetwork officially became part of the LOD Cloud.
