Spatial edge services

Ubiquitous and context-aware sensors are increasing in number and aim at providing comfort and better life quality. They are spatially distributed and their computation capacity are still under-exploited. This article discusses spatial edge services, a new generation of services exploiting IoT and spatially distributed data. They result from collective and decentralized interactions of multiple computing entities. They rely on a logic and chemical-based coordination model. In this paper, we discuss several spatial edge services cases and present an actual deployment and a prototype example. We discuss evaluation results, in particular scalability and accuracy. Spatial edge services provide innovation capabilities for the software industry, connected objects manufacturers and edge computing industry. Future work tackles on-the-fly service composition with requested quality of service (QoS).
