Cognitive computing and networking are closely related emerging technologies for communication in modern networked systems to meet the demand of exponentially increasing network subscriptions and data traffic. Techniques related to 5G, edge/fog computing, RF spectrum sensing, dynamic spectrum sharing, wireless virtualization, software defined networks, cognitive radio networks, software-defined radios, cyber-physical systems/Internet of Things, and public safety communication are among the areas of focus under cognitive computing and networking. Cognitive computing borrows the ideas from human cognitive systems to train networked devices to act/think and reasoning like a human mind. Cognitive networking refers to developing networks with a cognitive process (i.e., machine learning, knowledge representation, adaptive network management) that can give better service to users by learning operating environment and adapting network parameters based on the observed conditions. Applying cognition across the entire protocol stack is taking the cognitive computing and networking to the next important level of adaptive communication for networked systems. Furthermore, cognitive computing and networking are not only applicable to civilian communications, but also to tactical communications for adaptive communications in hostile environments.This symposium will focus on topics related to all aspects of cognitive computing and networking. The Cognitive Computing and Networking Symposium seeks original unpublished papers focusing on theoretical analysis, algorithm/protocol design, novel system architectures, experimental studies, emerging applications, standardizations, testbeds, etc. that report on emerging communications and networking technologies to improve network resource utilization, make coexistence of different wireless/mobile networks and make future networked systems autonomous and self-reconfigurable. The goal of this symposium is to bring together and disseminate the latest developments and technical solutions concerning various aspects of cognitive computing and networking technologies.
