Optimal user-centric relay assisted device-to-device communications: an auction approach

摘要: Device-to-device (D2D) communication has recently attracted much research attention because of its potential to increase the capacity cellular networks. Most existing works aim maximise overall system throughput (system-centric), which ignores actual traffic demands D2D users. In this study, authors consider user-centric relay assisted communications where users have different evaluations for significance every unit increased data rate. By considering users, propose a Vickrey–Clarke–Groves auction based allocation mechanism (ARM) in user submits bid basestation (BS). The submitted bids indicate users’ valuation on BS then allocates relays by maximising social welfare while maintaining predefined rate requirement A payment scheme charge using is designed, and show that truthful. also extend results general case provide ARM accordingly. Extensive simulation are provided demonstrate performance proposed mechanisms.
