Integrating pervasive middleware with social networks in SAPERE

Any middleware for pervasive computing services has to effectively support both spatially-situated activities and social models of interactions. In this paper, we present the solution integrated in the tuple-based SAPERE middleware to tackle this problem. The idea is to exploit the graph of a social network along with relations deriving from spatial proximity to rule the actual topology of interactions among devices, users and services. The proposed approach can facilitate the autonomous and adaptive activities of pervasive services while accounting for both social and spatial issues, can support effective service discovery and orchestration, and can enable tackling critical privacy issues.
