Community-based message transmission scheme in opportunistic social networks

Abstract

Since the mainstream forwarding protocol in opportunistic networks does not consider the sociality of node movement,a layering routing algorithm based on copy restriction and human sociality was proposed.This algorithm could dynamically adapt to divide network nodes into different communities according to the nodes intensity of social relation,in which the message copy redundancy was reduced by restricting the number of message copies,and the nodes of high activity were utilized to drive the forwarding and transferring of messages.The simulation results show that it can ensure higher delivery ratio and relatively lower delivery delay,and also reduce the resource consumption of network.
