Mobile Device-to-Device Video Distribution

ACM Transactions on Multimedia Computing, Communications, and Applications, 2016
As video traffic has dominated the data flow of smartphones, traditional cellular communications face substantial transmission challenges. In this work, we study mobile device-to-device (D2D) video distribution that leverages the storage and communication capacities of smartphones. In such a mobile distributed framework, D2D communication represents an

Secure Device-to-Device Caching With Blockchain

IEEE Internet of Things Journal, 2022
Caching and distributing of network packets among devices has been accepted by the research community as a cost-effective method of transferring especially audio-video data among mobile users. Another newly established technology, blockchain, has been successfully applied to decentralized financial systems like Bitcoin.

Robust Multicast Device-to-Device Communication

2018 IEEE International Conference on Advanced Networks and Telecommunications Systems (ANTS), 2018
Device-to-device (D2D) multicast communication can be employed in distributing popular content among similarly interested groups thereby reducing the load on the network. When the network multicasts a requested file to a cluster or group of users, some members of a cluster may not receive the sent data correctly and so may require re-transmission by ...

Device to device communication: A survey

Journal of Network and Computer Applications, 2019
Abstract With the advanced communication technology, the number of users and applications are increasing exponentially leading towards the scarcity of resources and an increase in power consumptions. The data traffic on the base station also rises with the number of users.

Latency Aware NOMA Based Device-to-Device Communication

2018 European Conference on Networks and Communications (EuCNC), 2018
Device-to-Device (D2D) links in cellular networks are expected to satisfy the increasing the local data traffic demands. This technique aims to admit more users into the network, providing spectral gains over traditional cellular communication. In this paper, we study a latency-aware resource allocation problem in which cellular devices in proximity ...
