In this paper, the authors present a novel Knowledge Sharing Protocol (KSP) for semantic technology empowered ubiquitous computing systems. In particular the protocol is designed for M3 which is a blackboard based semantic interoperability solution for smart spaces. The main difference between the KSP and existing work is that KSP provides SPARQL-like knowledge sharing mechanisms in compact binary format that is designed to be suitable also for resource restricted devices and networks. In order to evaluate the KSP in practice they implemented a case study in a prototype smart space, called Smart Greenhouse.
