“…In Case A.4, one device was out of the range of the coordinator but in the range of other devices, as shown in Figure 13. Case A.5 was the same as Case 4 and all devices kept the same positions except for the device closer to the coordinator, which was moved to the limit range of the coordinator [33,34], as shown in Figure 14. LED strips of various colors (red, yellow, and green) were used to simulate the traffic lights and were turned on and off by a microcontroller.…”

This paper presents a traffic light system based on wireless communication that provides a support infrastructure for intelligent control in the context of smart cities and aerotropolis areas. An aerotropolis is a metropolitan subregion with an infrastructure centered an airport. Traffic intensity is increasing all over the world. Intelligent dynamic traffic light system control is being sought to replace classic conventional manual and time-based systems. In this work, a wireless sensor network is designed and implemented to feed real-time data into an intelligent traffic light system control. A physical prototype is implemented for experimental validation outside the laboratory environment. The physical prototype shows robustness against unexpected issues and local failures. The results are positive in terms of the scope of experience gained, and there is potential for these tests to be extended to larger areas.

“…The higher investment and adoption of IoT support leads to an increase of IoT solutions offered in the market. The diversified offer of IoT technologies and solutions to solve the same problems and suppress the same needs, lead to new challenges [3,9,10,[13][14][15][16]. This multiplicity of solutions brings an extra effort to assure extra security measures that can overcome existing threats and overseen future risks [17].…”

Many industries, such as aeronautics construction are still equipped with legacy machines and are not keen to change old, however fully functional, equipment to new ones. Hence, an upgrade must be found to cope the legacy and fully functional machines to IoT technologies. This paper is a contribution to embrace those challenges in a new IoT architecture able to support the creation of solutions for Smart Industries. Internet of Things is increasing acceptance and the infrastructure for them is becoming available. This leads to an insurgence on investments and development of new dedicated IoT infrastructures. Industries need to adapt quickly to this constant technological evolution, implementing measures and connecting machines and robots at critical points to the Internet, instrumenting them using the concept of IoT, with the major goal of implementing a flexible, secure, easy to maintain and capable to evolve infrastructure, when legacy equipment is involved. The availability of machines and other critical assets directly affects the effectiveness of manufacturing operations. The architecture design offers security, flexibility, simplicity of implementation and maintenance, and is resilient to failures or attacks and technologically independent. Field tests are reported to evaluate key aspects of the proposed architecture.
