In recent years, there has been dramatic proliferation of research concerned with fifth-generation (5G) mobile communication\nnetworks, among which device-to-device (D2D) communication is one of the key technologies. Due to the intermittent connection\nof nodes, the D2D network topology may be disconnected frequently, which will lead to failure in transmission of large data files.\nIn opportunistic networks, in case of encountering nodes which never meet before a flood message blindly to cause tremendous\nnetwork overhead, a novel opportunistic network routing protocol based on social rank and intermeeting time (SRIT) is proposed\nin this paper. An improved utility approach applied in utility replication based on encounter durations and intermeeting time is\nput forward to enhance the routing efficiency. Meanwhile, in order to select better candidate nodes in the network, a social graph\namong people is established when they socially relate to each other in social rank replication. The results under the scenario show\nan advantage of the proposed opportunistic network routing based on social rank and intermeeting time (SRIT) over the compared\nalgorithms in terms of delivery ratio, average delivery latency, and overhead ratio.
