Guest Editorial Special Issue on Collaborative Edge Computing for Social Internet of Things Systems

The emerging applications for smart cities intend to promote the quality of citizens’ life. Among them, ubiquitous user connectivity and real-time computation offloading are significant for the ever-increasing requirements of delay-sensitive and mission-critical applications. By integrating human social behaviors (such as relationship, similarity, community, and social ties) with physical Internet of Things (IoT) systems, social IoT systems are promising to provide ubiquitous connectivity among users. As the applications of social IoT systems are transferring from information dissemination to user entertainment (such as image identification, online games, and augmented reality), computation offloading is significant to reduce the execution delay of applications.
