Efficiency Resource Allocation for Device-to-Device Underlay Communication Systems: A Reverse Iterative Combinatorial Auction Based Approach

摘要: Peer-to-peer communication has been recently considered as a popular issue for local area services. An innovative resource allocation scheme is proposed to improve the performance of mobile peer-to-peer, i.e., device-to-device (D2D), communications an underlay in downlink (DL) cellular networks. To optimize system sum rate over sharing both D2D and modes, we introduce reverse iterative combinatorial auction mechanism. In auction, all spectrum resources are set units, which bidders compete obtain business while packages pairs auctioned off goods each round. We first formulate valuation unit, basis auction. And then detailed non-monotonic descending price algorithm explained depending on utility function that accounts channel gain from costs system. Further, prove auction-based cheat-proof, converges finite number iteration rounds. explain non-monotonicity update process show lower complexity compared traditional allocation. The simulation results demonstrate efficiently leads good rate.
