With the immense increase of population density, many challenges facing organizations and governments. Thus, it has become mandatory to turn up our cities to be intelligent by introducing IoT and smart grids to build smart buildings, smart communication technologies, smart healthcare systems, smart transportation, etc. Smart cities guarantee the healthy living of indoor inhabitants by sensing, processing and controlling all possible indoor–outdoor measures. In this paper, we develop a framework that systematically builds a reliable and secure Smart City Model (SCM) to be integrated then exploited by the building information model (BIM). SCM encloses both physical and digital models which highlight smart buildings in particular. First, the proposed solution identifies and models SCM components including their appropriate architectures that are responsible for communication, extension, information flow, and protection. To ensure SCM functional and security requirements, we develop a sound hybrid approach that relies on formal methods and network analysis. Uppaal model checker is used to verify the satisfiability of the smart city requirements whereas Cooja is deployed to simulate the connectivity and the communication coverage of the developed SCM. The obtained results, in Uppaal, showed that the different implemented scenarios are satisfying the functional correctness and security policies. Moreover, the simulation through Cooja showed that how different obstacles and positions of nodes affect the communication coverage and the energy consumption regarding the deployed nodes. Experimentally, the effectiveness of the developed framework has been shown through practical scenarios that are difficult to model and analyze.

随着人口密度的急剧增加，组织和政府面临许多挑战。因此，通过引入物联网和智能电网来构建智能建筑、智能通信技术、智能医疗系统、智能交通等，使我们的城市变得智能化已成为强制性要求。 智能城市通过传感保证室内居民的健康生活，处理和控制所有可能的室内外措施。在本文中，我们开发了一个框架，该框架系统地构建了一个可靠且安全的智能城市模型 ( SCM )，该模型将被集成，然后由建筑信息模型 (BIM) 加以利用。SCM包含物理和数字模型，特别突出智能建筑。首先，建议的解决方案识别和建模SCM组件包括负责通信、扩展、信息流和保护的适当架构。为确保SCM功能和安全要求，我们开发了一种基于形式化方法和网络分析的完善的混合方法。Uppaal 模型检查器用于验证智慧城市需求的可满足性，而 Cooja 用于模拟开发的SCM的连接性和通信覆盖范围. 在 Uppaal 中获得的结果表明，不同的实现场景都满足功能正确性和安全策略。此外，通过 Cooja 进行的模拟表明，节点的不同障碍物和位置如何影响已部署节点的通信覆盖范围和能耗。在实验上，已经通过难以建模和分析的实际场景证明了所开发框架的有效性。
