TOWARDS COMPATIBILITY OF CONTEMPORARY GEOSPATIAL STANDARDS WITH THE FOG COMPUTING CONCEPT

Abstract

This position paper considers the possibility of implementation of the Fog Computing paradigm into the contemporary Geographic Information Systems (GISs) and into the geospatial Web services that provide data access. In particular, the paper is focused on the issue of compatibility of the existing geospatial standards developed by the Open Geospatial Consortium (OGC) with the principles of Fog information systems. The WMS, WMTS, WFS, WCS, WPS and CS standards are highlighted. The conclusion is made that the OGC standards can be extended by new request types to ensure the implementation of Fog Computing functionality and the inverse compatibility with currently used Cloud-based Web services. Two fundamental problems are highlighted that arise when designing geospatial Fog Web services. The first one is the need to provide processing and management operations on spatial data at client devices (particularly on mobile devices) when the geospatial Fog Web service is deployed on such a device. The second problem is the necessity to insure the geospatial data transmission using the HyperText Transfer Protocol, which is used in contemporary geospatial Web services. The JavaScript programming language and the WebRTC technology (Web Real-Time Communication) are mentioned as examples of basic technologies that can be applied to geospatial Fog Web services. It is concluded that contemporary technologies used in GISs and Web services ensure in general the implementation of Fog Computing into geospatial data management tasks. However, the known examples of such implementation do not exist today, and further research and development are required in this direction.
