This workshop aims at gathering researchers and developers from the fields of the Internet of Things, Pervasive and Ubiquitous Computing and Smart Cities to discuss the technologies and research challenges associated to new applications and services in Smart Livable Cities. The Internet of Things is a key enabler for the realization of smart cities as it allows for the pervasive interaction with/between the smart things leading to an effective integration of information into the digital world. These smart (mobile) things – which are instrumented with sensing, actuation, and interaction capabilities - have the means to exchange information and influence the real world entities and other actors of a smart city eco-system in real time, forming a smart pervasive computing environment to achieve a more livable city. Pervasive Internet of Things and Smart Cities (PITSaC) is an International Workshop focused on the extension and integration aspects of the secure Internet of Things and pervasive computing technologies. The objective is to reach a global access to the services and information through, on the one hand, the so-called Web of Things and on the other hand, the efficient support for global communications, in order to embrace the machine to machine (M2M) communications in the future Internet of Things composed of IPv6 network and various smart things. This workshop will also address further issues such as the adaptation of legacy technologies and RFID to IPv6 and the Future Internet of Things, security and privacy requirements in Smart Cities and the design of a secure and privacy-aware Internet of Things as well as the definition of new advanced architectures and models for the Internet and its application to smart livable Cities.
