Abstract
‘Smart cities’ is a concept that embraces many technologies and solutions in sensing and carrying a city’s data through a network for further processing and analysis. Smart cities’ main priority is citizens and environmental sustainability. In practice, wireless sensors networks over mesh networks are the approach employed most of the time. In terms of wireless communications technologies, Bluetooth low energy offers a robust, low cost, and low power consumption option. The recently published Bluetooth mesh profile specification addresses the most relevant challenges on that paradigm, adding secure multicast communications capabilities. A framework to create Smart Cities services was proposed and a traffic light service was used to demonstrate specification applicability for smart cities’ services. The proposed service showed that data may be collected and shared between devices in a mesh network through and over a metropolitan area. The specification’s strengths were demonstrated and some topics for further development were identified.
Highlights
Smart cities is a growing concept around the world [1,2,3,4]
The first thing noted was that devices may provide and configure themselves
Functions invoked in the reaction of provisioning and configuration messages and commands are available in API and may be used e.g., on the application layer
Summary
Smart cities is a growing concept around the world [1,2,3,4] It includes many initiatives which provide meaningful services to citizens, with its main focus being on their welfare, services availability, and environmental sustainability. Those several solutions employ many different technologies in such a heterogeneous way that services may not interoperate, or may not be widely available for users. In this scenario, a solution based on a widely accepted standard is desirable. There is no hierarchy in those networks, devices may communicate directly with any other(s), and data may flow in any direction [3,5]
