# A Survey: Future Smart Cities Based on Advance Control of Unmanned Aerial Vehicles (UAVs)
## 7 Future of Smart Cities
The research community is called upon to address these issues in future investigations, emphasizing the need for innovative solutions to handle these challenges and enhance the capabilities of UAV imaging processing techniques. * The necessity for developing efficient and real-time inspection methods for transmission lines using UAVs. It suggests that various approaches, such as data analysis tools, cooperative platforms, robust tracking and detection methods, vision-based inspection techniques, and UAV low-altitude photogrammetry, should be proposed to address this need. These methods are expected to enable effective and efficient inspection of transmission lines, enhancing reliability and reducing downtime through timely detection of issues and maintenance [129]. * Researchers should prioritize the implementation of new sensing devices, special cameras, multi-decision-making algorithms, multispectral imagery, and the coexistence of edge/fog computing or remote sensing and positioning mechanisms. These technologies are essential for supporting the efficient detection of soil properties, mapping crop status, and capturing other farming characteristics. By focusing on these areas, researchers can contribute to the development of advanced tools and methodologies for precision agriculture, enabling farmers to make informed decisions and optimize their farming practices. * The importance of proposing additional strategies for sensing, guidance, navigation, and localization in the context of UAV delivery systems. It emphasizes that any shortcomings in these techniques can lead to inaccuracies and delays in the delivery of parcels. To address this, researchers are encouraged to investigate low-cost and efficient sensing devices and localization systems. By developing advanced technologies in these areas, the accuracy, reliability, and timely delivery of parcels through UAVs can be improved, contributing to the efficiency and effectiveness of UAV-based delivery services [130]. * The need for further research contributions in utilizing UAVs for resilient public safety networks. It emphasizes that future studies should focus on public safety communications, public health in disaster scenarios, and the integration of blockchain technology in UAVs to enhance health monitoring systems. It mentions a recent study [131] that specifically addressed the use of UAVs in public safety networks. These research efforts aim to enhance the capabilities of UAVs in supporting public safety operations, improving communication systems, and enabling effective health monitoring in emergency situations. * The importance of researchers finding adaptive control and cooperative algorithms for multi-UAV systems. With the increasing presence of thousands of UAVs in the air, forming networks to perform tasks like drone light shows, QR code generation, and aerial promotion, there is a need for robust coordination mechanisms to support such applications. Adaptive control techniques [131; 132], can enable UAVs to adapt to changing conditions and optimize their performance, while cooperative algorithms facilitate effective collaboration among multiple UAVs. By developing and implementing these algorithms, researchers can enhance the coordination and capabilities of multi-UAV systems, enabling them to perform complex tasks efficiently and effectively [133; 132]. * Further research to assess the impact of adverse weather conditions on the robustness of UAVs and ensure the successful implementation of missions. Adverse weather, such as strong winds, rain, snow, or extreme temperatures, can significantly affect the performance and reliability of UAVs. It is crucial to understand how different weather conditions can impact UAV operations, including flight stability, control, communication, and sensor performance. * The focus must be on comprehensive regulations and adherence to specific guidelines. The certifications ensure the safe and compliant operation of UAVs in various airspace environments and jurisdictions.
