IoT technology is a fundamental infrastructure for information transmission and integration in smart city implementations to achieve effective fine-grained city management, efficient operations, and improved life quality of citizens. Smartcity IoT systems usually involve high volume and a variety of information circulation. The information life-cycle also involves many parties, stakeholders, and entities such as individuals, businesses, and government agencies with their own objectives which needed to be incentivized properly. As such, recent studies have modeled smart-city IoT systems as a market, where information is treated as a commodity by market participants. In this work, we first present a general information-centric system architecture to analyze smart-city IoT systems. We then discuss features of market-oriented approaches in IoT, including market incentive, IoT service pattern, information freshness, and social impacts. System design challenges and related works are also reviewed. Finally, we optimize information trading in smart-city IoT systems, considering direct and indirect network externalities in a social domain.

智慧城市的物联网中的信息交易：面向市场的分析

物联网技术是智慧城市实施中信息传输和集成的基本基础设施，可实现有效的细粒度城市管理，高效运营和改善居民的生活质量。智能城市物联网系统通常涉及大量和各种信息流通。信息生命周期还涉及许多各方，利益相关者以及诸如个人，企业和政府机构之类的实体，它们各自的目标需要适当地激励。因此，最近的研究已经将智能城市物联网系统建模为一个市场，市场参与者将信息视为商品。在这项工作中，我们首先提出一种以信息为中心的通用系统架构，以分析智能城市物联网系统。然后，我们讨论物联网中以市场为导向的方法的特点，包括市场激励，物联网服务模式，信息新鲜度和社会影响。系统设计挑战和相关工作也进行了审查。最后，考虑到社交领域中直接和间接的网络外部性，我们优化了智能城市物联网系统中的信息交易。
