Social-Tie-Based Information Dissemination in Mobile Opportunistic Social Networks
A Mobile Opportunistic Social Network (MOSN) is a new type of Delay Tolerant Network (DTN), in which the mobile users contact each other opportunistically. Information dissemination is a challenging problem in MOSNs, due to uncertainty and intermittent connectivity. In this paper, the authors propose a distributed social tie strength calculation mechanism to identify the relationship between each set of pairwise mobile nodes. Following arguments originally proposed by Mark Granovetter's seminal 1973 paper, The Strength of Weak Ties, the majority of the novel information dissemination is generated by weak ties.
