Abstract:
Device-centric wireless networks, including Deviceto- Device communications and Multi-hop Cellular Networks, are expected to be a relevant component of future 5G wireless networks. Traditionally, opportunistic networking has been proposed for disconnected networks that cannot always reliably ensure real-time end-to-end connections. However, previous studies have demonstrated that opportunistic schemes can also be utilized in connected networks to improve their efficiency by intelligently exploiting context- and content-awareness. In this context, this paper proposes and evaluates a mechanism to select the adequate configuration of opportunistic cellular communications in single-hop and multi-hop cellular networks. To this aim, the mechanism probabilistically identifies for each communications mode the adequate times for cellular transmissions to take place in order to reduce the cellular channel occupancy and improve its capacity. The obtained results show that the proposed scheme reduces the channel occupancy of cellular transmissions for delay-tolerant information by up to 70% compared to conventional single-hop cellular communications
