Resource allocation, interference management, and mode selection in device-to-device communication: A survey

For us to meet the demands of fifth generation technologies, device-to-device (D2D) communication is foreseen to be an important part of fifth generation networks. Device-to-device communication brings significant improvement in user's throughput, battery life, communication delay, and resource usage. Device-to-device links share the same resource with the cellular links that results in interference between cellular users and D2D user equipments. This interference can be managed by suitable resource allocation algorithms. The selection of D2D or cellular communication mode is also a hot research issue. Many research works are available in literature on the aforementioned issues regarding D2D communication, but there is no survey available in the literature. To facilitate the researchers, we present a detailed and systematic survey on resource allocation, interference management, and mode selection in D2D communication in this paper. Initially, the taxonomy based overview of D2D communication is provided, and the classification of the works is outlined. Then, the works regarding mode selection are reviewed in detail. Furthermore, interference management schemes to handle the interference caused by the underlying nature are also surveyed. Then, the available literature on resource allocation schemes in D2D perspective are presented. Finally, some open research problems are identified that deserve further research.
