In this paper, we proposed a context-aware group buying mechanism to reduce users' data
cost based on the content similarity. Each user's cost is formulated as the combination of the …

Device-to-device content sharing is widely considered as an effective response to the
prevalence of multimedia content sharing and local services. To ensure its advantages, how …

Recently, cellular networks have become severely overloaded by social-based services,
such as YouTube, Facebook, and Twitter, in which thousands of clients subscribe to a …

This paper investigates relay-based schemes in cellular systems, where multihop device-to-
device (D2D) communications are exploited for content uploading toward the eNodeB. All …

Device-to-device (D2D) communication has been proposed as a promising technology for
future cellular communication systems due to its advantages of high spectrum efficiency, low …

Device-to-Device (D2D) content sharing is regarded as an effective way to support an
explosion in demand for content sharing and local services. The underlying principle is that …

In 5G cellular networks, device-to-device (D2D) communication has undoubtedly become a
general trend to increase spectral efficiency while reducing communication delay. In …

With the emerging demands for local area services of popular content downloading, D2D
communication is recognized as a promising technical support for cellular networks. In this …

The device-to-device (D2D) channels allow content sharing when two devices are in close
proximity, which can help improve resource utilization and network capacity. The data …

In this work, we propose a dynamic distributed resource sharing scheme which jointly
considers mode selection, resource allocation, and power control in a unified framework for …
