Special Issue Information

Dear Colleagues,

With the boom of technology and the economy, there is a continuously increasing demand for a better and more convenient life, with enhanced sustainability, efficiency, and resilience. Smart cities are emerging with various advanced technologies, such as infrastructure monitoring, intelligent traffic management, and greenhouse gas mitigation. Constructing a smart city is an important part of improving the quality of urban life, and the development of smart cities requires the systematic analysis of relevant data. Data processing and intelligent computing which integrate data mining, data analysis, computer vision, deep learning, computation resource allocation, task offloading, and task downloading are promising technologies for smart cities. This poses new challenges in investigating these technologies as well as their potential applications in operating and managing various aspects of smart cities. Therefore, there is a strong motivation to explore methods or solutions through innovative and connected technology and data to handle constrained, complex, large-scale, and multi-objective optimization problems for smart cities, which has attracted extensive attention from both academics and industries.

This Special Issue seeks to present new ideas and approaches in the field of smart cities. It targets a wide range of areas, including intelligent transportation systems, smart campuses, digital logistics, efficient management, etc., as well as related and recent advances in data processing and intelligent computing for different fields of smart cities, such as massive data collection and analysis, large-scale computational science, artificial intelligence, city planning, intelligent infrastructures, machine learning, deep learning, and reinforcement learning. Simulations, datasets relevant to smart cities, and the deployment of algorithms on existing city areas are also covered.

The topics of interest for this Special Issue include, but are not limited to, the following topics:

  • Advanced strategies for intelligent computing;
  • High-performance data analysis and processing;
  • Machine learning, deep learning, and reinforcement learning;
  • Big-data-based applications, algorithms, and systems design;
  • Use cases and applications for intelligent transport and logistics systems;

ChatGPT plays significant roles in the third decade of the 21st Century. Smart cities applications can be integrated with ChatGPT in various fields. This research proposes an approach for developing large language models using generative artificial intelligence models suitable for small- and medium-sized enterprises with limited hardware resources. There are many generative AI systems in operation and in development. However, the technological, human, and financial resources required to develop generative AI systems are impractical for small- and medium-sized enterprises. In this study, we present a proposed approach to reduce training time and computational cost that is designed to automate question–response interactions for specific domains in smart cities. The proposed model utilises the BLOOM approach as its backbone for using generative AI to maximum the effectiveness of small- and medium-sized enterprises. We have conducted a set of experiments on several datasets associated with specific domains to validate the effectiveness of the proposed model. Experiments using datasets for the English and Vietnamese languages have been combined with model training using low-rank adaptation to reduce training time and computational cost. In comparative experimental testing, the proposed model outperformed the ‘Phoenix’ multilingual chatbot model by achieving a 92% performance compared to ‘ChatGPT’ for the English benchmark.

Utilizing GIS technology and spatial analysis methodologies, this study endeavours to delve into and grasp the localized attributes of the regional units under investigation from a geographical vantage point, as well as the interrelationships among these units. This endeavour encompasses the identification and quantification of developmental patterns, the assessment of trends, and the resolution of any intricate issues about geographical location to make prognostications and informed decisions. Classic spatial analysis techniques such as the geographic concentration index, kernel density analysis, Thiessen polygons, and spatial autocorrelation analysis (Moran’s I index) are employed in this inquiry. Initially, the study utilized the nearest neighbour index and geographic concentration index to gauge the equilibrium, proximity, and concentration of the spatiotemporal distribution of smart health elderly care demonstration bases across 31 provinces in China. Upon confirming the spatial clustering and imbalance of the distribution of elderly care demonstration bases in China, kernel density analysis was applied to compute the density of point features surrounding each output raster cell and to visually represent the spatiotemporal distribution status of the bases. Finally, Thiessen polygons and spatial autocorrelation analysis (Moran’s I index) were introduced to further elucidate and validate the spatial distribution patterns of the elderly care demonstration bases. The findings of the research reveal that smart health and elderly care bases in China manifest spatial clustering, predominantly concentrated in the central and eastern regions of the country. The overarching pattern embodies a spatial model characterized by a “concentration in three poles with multiple cores surrounding”. Ultimately, the study offers recommendations for the nexus between three principal mechanisms: market-driven development mechanisms, policy-driven development mechanisms, and technology-driven development mechanisms, advocating for the further progression of intelligent construction to attain the sustainable development of demonstration bases. This research furnishes a scientific foundation for the planning and industrial advancement of pertinent departments. Full article

In next-generation mobile communication scenarios, more and more user terminals (UEs) and edge computing servers (ECSs) are connected to the network. To ensure the experience of edge computing services, we designed an unmanned aerial vehicle (UAV)-assisted edge computing network application scenario. In the considered scenario, the UAV acts as a relay node to forward edge computing tasks when the performance of the wireless channel between UEs and ECSs degrades. In order to minimize the average delay of edge computing tasks, we design the optimization problem of joint UE–ECS matching and UAV three-dimensional hovering position deployment. Further, we transform this mixed integer nonlinear programming into a continuous-variable decision process and design the corresponding Proximal Policy Optimization (PPO)-based joint optimization algorithm. Sufficient data pertaining to latency demonstrate that the suggested algorithm can obtain a seamless reward value when the number of training steps hits three million. This verifies the algorithm’s desirable convergence property. Furthermore, the algorithm’s efficacy has been confirmed through simulation in various environments. The experimental findings ascertain that the PPO-based co-optimization algorithm consistently attains a lower average latency rate and a minimum of 8% reduction in comparison to the baseline scenarios.
