Next-generation wireless networks (NGWN) aim to support diversified smart applications that require frequent data exchanges and collaborative data processing among multiple stakeholders. Data management (DM), including data collection, storage, sharing, and computation, plays an essential role in empowering NGWN. However, DM for NGWN faces two significant challenges: stakeholders' data cannot be easily managed across different trust domains under a distributed network architecture; and privacy preservation requirements of personal data become more rigorous under new privacy regulations. To explore possible solutions to address the challenges, we first investigate the state-of-the-art architecture designs for DM and emphasize advantages of a blockchain-based DM architecture. Then we summarize existing privacy-preserving techniques in terms of advantages and challenges when being applied to DM. In addition, we review recent privacy regulations with their impacts on DM and discuss the existing solutions with privacy regulation compliance based on blockchain. Finally, we identify further research directions for achieving DM with privacy preservation.

未来无线网络的数据管理：体系结构，隐私保护和法规

下一代无线网络（NGWN）旨在支持多样化的智能应用程序，这些应用程序需要多个利益相关者之间的频繁数据交换和协作数据处理。数据管理（DM），包括数据收集，存储，共享和计算，在增强NGWN的能力方面起着至关重要的作用。但是，用于NGWN的DM面临两个重大挑战：在分布式网络体系结构下，无法轻松地跨不同信任域管理涉众的数据；在新的隐私法规下，个人数据的隐私保护要求变得更加严格。为了探索解决挑战的可能解决方案，我们首先研究了针对DM的最新架构设计，并着重介绍了基于区块链的DM架构的优势。然后，我们将现有的隐私保护技术从应用于DM时的优势和挑战方面进行了总结。此外，我们回顾了最新的隐私法规及其对DM的影响，并讨论了基于区块链的符合隐私法规合规性的现有解决方案。最后，我们确定了进一步实现具有隐私保护功能的DM的研究方向。
