Analysis of Social Network Algorithms in Delay Tolerant Networks

Abstract

An existing social based routing protocol for opportunistic networks. SimBet uses similarity, betweenness centrality as its forwarding metrics. Although similarity shows how likely a pair of nodes belongs to the same community, it does not express how closely these nodes are connected. SimBet exhibits the direct link probability into the forwarding metrics, but it ignores the indirect link probability through neighbor nodes, so it doesn’t applicable in real world scenario. To overcome this problem, we propose to incorporate Human opinion dynamics HOD with SimBet called SimBet-HOD. In this a trust of a node is based on the opinion of its neighbor nodes and also the previous interactions of the node with the concerned node. we have been calculate social rank, social influence, and the distance between nodes which are encountered randomly. This will always update a SimBet table of nodes in an random environment. Due to which an Average number of hops, Average delay and Total number of forwards in comparison with previous approaches are reduced.
