Data exchange between mobile devices without organizing the connections

Resumen

The article discusses one approach to organizing data exchange between closely spaced mobile devices, which does not require a direct connection between devices and does not use third-party (cloud) storage. The article was written based on the results of the final qualifying work performed at the faculty of the CMC of Lomonosov Moscow State University. The paper proposes a mobile application for the Android platform, based on the network spatial proximity model, which allows you to exchange contact information with other mobile devices located nearby. Within the framework of this model, a limited area of propagation of wireless network signals is used to determine spatial proximity. Due to the complete exclusion of working with geo-coordinates, such networks may not necessarily be stationary nodes with a known location. The main usage model is the software creation of such wireless networks, specifically for the provision of services that use location information. At the same time, advertising (representative) information of such nodes can be used to transfer user data.
