Exploiting Friendship Relations for Efficient
Routing in Mobile Social Networks

Abstract—Routing in delay tolerant networks is a challenging problem due to the intermittent connectivity between nodes
resulting in the frequent absence of end-to-end path for any source-destination pair at any given time. Recently, this problem
has attracted a great deal of interest and several approaches have been proposed. Since mobile social networks (MSN) are
increasingly popular type of DTNs, making accurate analysis of social network properties of these networks is essential for
designing efficient routing protocols. In this paper, we introduce a new metric that detects the quality of friendships between
nodes accurately. Utilizing this metric, we define the community of each node as the set of nodes having close friendship
relations with this node either directly or indirectly. We also present Friendship Based Routing in which periodically differentiated
friendship relations are used in forwarding of messages. Extensive simulations on both real and synthetic traces show that the
introduced algorithm is more efficient than the existing algorithms.
