Slowly but steadily the Internet of Things (IoT) is penetrating and transforming our lives. The first stage of the IoT evolution consisted in the deployment of RFID tags for facilitating routing, taking inventory and loss prevention of goods. After that we witnessed the first wave of RFID and sensor network integration toward vertical-market applications. Nowadays, new generations of RFID tags, in particular active RFID tags, often include built-in sensing capabilities. Whereas, applications based on sensor networks often require means for unique identification and discovery of objects, which are monitored by the sensor network. The convergence of sensing and identification technologies, together with communication and computation systems, enables us to gain impressive awareness about the state of the real world and will drastically change the way we interact with our environment. Urban planning, smart cities, intelligent shopping, smart meters, home automation, security and surveillance, industrial applications like process industry automation, supply chain, smart product management and agricultural applications are examples of potential applications for real-world systems. Even though the advent of the IPv6/6LoWPAN protocol suite solved several technical issues, many challenges are still open in the research and development communities concerning the choice of communication paradigms, architectures and technology. The main focus of this workshop is on technologies, applications and paradigms of the IoT that are already deployed or are under investigation and that belong to the second stage of the IoT evolution. The next step in the evolution of the IoT is its characterization as the underlying technological layer needed to shape and substantiate higher layer concepts such as semantic web and personalization. In fact, the IoT is the enabling technology to allow virtual and physical worlds to converge in what has already been defined as Web 3.0. If, currently, the IoT is the most suited companion of blogging, podcasting, tagging and social networking, we can imagine that its evolution will foster the rise of statistical, machine-constructed semantic tags and algorithms through the construction and exploitation of semantic databases empowered by distributed and cloud computing. The integration of the IoT with semantic databases, capable of delivering accurate information about the nature and the state of every physical object will introduce a staggering amount of new applications opportunities as well as potentially lead to an ultimate “Big brother scenario”. Therefore, a particular interest will have to be given to appropriate security and privacy control mechanisms. The secondary focus of this workshop is on IoT vision and perspective towards Web 3.0.
