SPF

SPF (as in "Sieve, Process, and Forward") is a Software-Defined Networking (SDN) and Value-of-Information (VoI) based solution for dynamic IoT applications in urban computing environments.

SPF aims to address the explosion of IoT data by processing it at the edge of the network, in close proximity to the source of its generation. In order to filter information objects, SPF uses a minimum content difference threshold for new IoT data to be considered for processing and dissemination. In addition, SPF prioritizes dissemination of critical information by ranking objects according to their corresponding VoI metric.
