Social-based Routing in Opportunistic Mobile Networks: A Survey
Tieying Zhu and Milica Stojmenovic
Recently, social-based approaches, which attempt to exploit the social behavior of mobile nodes to guide routing decisions, have attracted lots of attention in routing design of opportunistic networks. This paper presents a survey of the social characteristics shown in opportunistic mobile networks and emphasizes how to measure the social characteristics in timevary contact graph. It discusses the typical social-based routing protocols and investigates the relationship among the routing performance, the mobility scenarios and routing protocols. This paper is concluded by discussing open questions and challenges in the design of social-based routing protocol between mobile devices.
