Ubiquitous Systems towards Green, Sustainable, and Secured Smart Environment

Expected goal of ubiquitous system is to prompt a tight integration among information, human beings, and their coexisting environment. 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 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. And this special issue intends to tackle such deluge issues in ubiquitous systems design, prompting a green, sustainable, and secured computing environment.
