Data-Request-Packet Broadcasting Approach for Mobile Opportunistic Networks with Unreliable Links

Abstract

With the wide application of mobile smart devices carried by humans, content dissemination by using Device-to-Device wireless communication technologies in Mobile Opportunistic Networks (MONs) attracts numerous attentions. However, traditional content dissemination approaches have not considered the efficiency of broadcasting interest packets to the providers in MONs with unreliable links. To increase the efficiency of broadcasting interest packets, we propose two data-request-packets broadcasting approaches with the goal of decreasing energy and communication consumption, in which the policy of self-adapting broadcasting time interval is applied. The extensive simulation results show that our proposed approaches greatly prolong the network lifetime, while maintaining higher delivery ratios compared with traditional approach.
