We present a new Pervasive IT Architecture as one of the first motivating manifestations of the Internet of Things. This new architecture consisting of a federated computing, storage and networking paradigm provides the foundation for billions of smart objects (IP based sensors, actuators, smart devices, etc) spanning home, industrial settings, vehicles, transportation systems to sense, predict and act on activities and events, in a timely and closed control-loop manner. We discuss the need for a new wireless architecture, including the role of ad-hoc & spontaneous networking, federated trusted anchors, smart object level security & mobility, smart middleware for peer-to-peer, peer-to-group and peer-to-cloud, and inter-cloud human/machine collaborative communications. We also address the importance of distributed big data analysis as a special focus of this new architecture, and its impact on the acceleration of development and adoption of immersive intent and contextual based geo-spatial decision spaces, where mashed-up isolated data sets from public, private and non-profit sources are combined with human natural collaborative interaction capabilities. Such emerging combination will produce higher situational awareness, context aware intent analysis of machines and human in a highly collaborative manner, and will provide context aware real-time/near-real-time response to events/activities. Finally, we discuss various IoT and Human Networks scenarios that will greatly benefit from such a platform, including smart & connected home, energy, cities and communities.
