Context-aware networking and communications: part 2 [Guest Editorial]

The general definition of context-aware communications and networking (CACN) was provided in the June 2014 Guest Editorial of Part 1 of this Feature Topic. Briefly speaking, there are two classes of context awareness: person context awareness and object context awareness. Context awareness may be implemented using quite different aspects under different environments and conditions, and at different layers. The relevant research topics in this area include context-aware network architectures, protocols, services and applications, context-aware green communications and computing networking, context-aware modeling and analysis methods, context-aware security approaches, context-aware distributed systems, context awareness in the Internet of Things, context-aware semantic networking, context-aware data storage and cloud computing, context-aware recommender systems, context awareness in smart spaces, context awareness in multimedia content distribution, adaptive and context-based multimodal interaction, location-aware services and context-aware location tracking, context-aware messaging, addressing, and routing, mobile phone sensing, personal awareness in smart environments, social context understanding and social interaction among peers, context-aware social networks, urban awareness for communications and networking, social agents and avatars, virtual humans for communications and networking, and standardization and regulation of context-aware information networking and communications.
