Enabling Architectures and Technologies for Smart Cities

The vision of smart cities has became a reality. Technological advances in low power devices and reliable communication and overall system architectures made it happening. However, there are plenty of improvements that still can be employed to further increase the efficiency of relevant systems or to provide new approaches that improve existing solutions. This special issue on Enabling Architectures and Technologies for Smart Cities of the JOURNAL OF COMMUNICATIONS SOFTWARE AND SYSTEMS aims to report on the recent advancements and developments in various aspects related to emerging hardware and software technologies enabling the IoT, such as RFID, WSN, system software architecture, integrated solutions, embedded systems, and so on. This issue recommended totally 10 papers for publication based on the standard reviewing process, where at least two constructive reviews and with guest editors comment have been received. Papers are split in two main groups focused mainly on system architectures that improve reliability in smart cities ([1- 5]), and hardware solutions ([6-10]) that are presented as either upgrades to exisiting solutions or new more efficient proposals. All of these were validated by analytics, simulations and/or testbed approaches.
