A Survey on Multimedia over 5G Networks for D2D Communication Based Wi-Fi Direct Technology

             Smart-Device to Smart-Device (D2D) communications over Wi-Fi Direct (WFD) technologies in 5G network is still faces many dilemmas especially if mention some services available to the users such as social sharing of video streaming, audio and caching solutions, with massive number of mobile users, considering rate-distortion (RD) characteristics for QoS with finding the best way to calculate distance between multi-hop candidate devices and whether the device is static or moving with regard to characteristics of flow traffic speed such as High-Speed railways and subway with the mobility feature of communications according to the future demands in 5G. In this article, we present a survey of current methodologies and techniques related to neighboring discovery in the network area, interference management, and low energy consumption communication and its impact on multimedia delivery.
