Trusted and secured D2D-aided communications in 5G networks

The design of the forthcoming fifth generation (5G) system shall meet severe requirement managing an always increasing amount traffic generated by both humans and machines, while guaranteeing data security. Among enabling technologies that will turn 5G into a reality, Device-to-Device (D2D) Multicasting certainly play key role because their capability to largely improve network resources utilization address emerging use cases requiring delivery same content large number devices. D2D communications can help traditional point-to-multipoint transmissions reducing multicast coverage area exploiting properly selected relay nodes as forwarders toward users with worse channel conditions. However, security issues are even more challenging for connections, exchange happens directly between in proximity. To enhance performance delivered 5G-oriented networks, this paper we SeT-D2D (Secure Trust D2D), according which trustworthiness inferred from direct interactions social-awareness parameters is exploited select nodes. Main contributions our research consist introduction model assessment nodes’ implementation mechanisms protect transmitted privacy involved users. conducted simulation campaign testifies ability proposed solution effectively nodes, leads improved performance.
