The growing communication and computing capabilities in the devices enlarging the connected world and improving the human life comfort level. The evolution of intelligent sensor networks and smart antennas has led to the development of smart devices and systems for real time monitoring of various environments. The demand of smart antennas and intelligent sensors significantly increases when dealing with multi-user communication system that needs to be adaptive, especially in an unknown adverse environment. The smart antennas-based arrays are capable to steer the main beam in any desired direction while placing nulls in the unwanted directions. Intelligent sensor networks integration with smart antennas will provide algorithms and interesting application to collect various data from the environment to make intelligent decisions.

The aim of this Special Issue is to provide an inclusive vision on the current research in the area of intelligent sensors and smart antenna-based systems for enabling various applications and technologies.
