From today´s INTRAnet of things to a future INTERnet of things: a wireless- and mobility-related view

In this article, we present the current status of the Internet of Things, and discuss how the current situation of many "Intranets" of Things should evolve into a much more integrated and heterogeneous system. We also summarize what in our opinion are the main wirelessand mobility-related technical challenges that lie ahead, and outline some initial ideas on how such challenges can be addressed in order to facilitate the IoT\´s development and acceptance in the next few years. We also describe a case study on the IoT protocol architecture.
