Dynamic network architecture (DNA) has emerged as a promising networking paradigm which establishes a low-cost ubiquitous network connectivity without the need for significant changes in software and hardware infrastructure. In this concept the major player in spectrum sharing process is the user itself hence the name user-centric spectrum sharing. Such user-based spectrum sharing concept is an opportunistic model due to the uncertainty in traffic patterns, which results in frequent interruption of the shared spectrum access. In this paper, end users (EUs) deal with this difficulty by choosing the least overloaded access points (APs) to have a longer access period without interruption. Moreover, we introduce spectrum outage probability parameter to investigate efficiency of spectrum sharing in DNA networks. The simulation results show that the network operators (NOs), dynamic access points (DAPs) and EUs significantly improve their utilities if they deploy a user-centric spectrum sharing model in DNA networks.
