In line with matured techniques, making systems lighter, smaller, but powerful becomes an emerging trend. To develop a smart environment, improvements to performance, sustainability, and security of conventional systems are essential. Taking smart home for instance, all devices are connected to a specific area networks and smart meters, and are controlled through demand side management techniques, where they can make sure all the devices are functional and stay controlled. With real-time pricing schemes, these techniques can achieve efficient energy usage as well as monetary expense reduction, and also enable the integration of renewable energy resources, and facilitate the peak-to-average load ratio reduction for balancing energy consumption. Although advantages can be envisioned, the design of secured ubiquitous systems and making them right-to-the-needs are highly desired.

This special issue intends to tackle such deluge issues in ubiquitous systems design, prompting them towards green, sustainable, and secured. High quality and state-of-the-art issues and results are welcome. Original and research articles are solicited in all aspects of including theoretical studies, practical applications, new techniques and experimental prototypes.
