Social-Aware Energy-Efficient Data Dissemination with D2D Communications

Abstract

With the high penetration rate of smart mobile devices, it is appealing to exploit device-to-device (D2D) communications for data dissemination, e.g., in disaster alerts and event notifications. The popularity of social networks also offers good opportunities to improve the efficiency of data dissemination. Though there have been some existing works on data dissemination with D2D and mobile social networks, many focus on mitigating the D2D co-channel interference to achieve high resource utilization. As mobile devices are power-limited, it is important to consider the energy efficiency and finishing time in data dissemination. In this paper, we aim at developing an effective solution for D2D data dissemination to balance between total energy consumption and transmission completion time. In particular, we propose novel algorithms for seed selection and transmission scheduling with a single seed or multiple seeds. Simulation results demonstrate that our solution outperforms two reference schemes in total energy consumption while achieving a good balance for transmission completion time.
