Abstract

Routing in opportunistic networks is very challenging as it must handle network partitions, long delays, and dynamic topology. Recently, the consideration of social characteristics of mobile nodes provides a new angle of view in the design of opportunistic routing protocols. In many opportunistic networks, a multitude of mobile devices are used and carried by people, whose behaviors are better described by social models. This opens the new possibilities of social-based routing, in which the knowledge of social characteristics of mobile users is used for making better opportunistic forwarding decision. In this book chapter, we briefly introduce several social properties (such as community, centrality, similarity, and friendship) which could be used for relay selection, and provide a broad survey of recent social-based opportunistic routing approaches.
