In the last few years, a stimulating idea is fast emergingin the wireless scenario: the pervasive presence around us of a variety of ¿things¿ or ¿objects¿, such as RFID, sensors, actuators, mobile phones, which, through unique addressing schemes, are able to interact with each other and cooperate with their neighboring ¿smart¿ c- ponents to reach common goals. This novel paradigm, named ¿The Internet of Things¿ (IoT) continues on the path set by the concept of smart environments and paves the way to the depl- ment of numerous applications with a signi cant impact on many elds of future every-day life. In this context, logistics, Intelligent Transportation Systems (ITS), business/process management,assisted living, and e-health are only a few examples of possible application elds in which this novel paradigm will play a leading role in the next future. Actually,manychallengingissues still needto be addressedand both technolo- calandsocialnodesuntiedbeforethe IoTideabeingwidelyaccepted.Centralissues are making a full interoperabilityof such devices possible, enablingtheir adaptation and autonomousbehavior, as well as guaranteeingtrust, privacy,and security. Also, the IoT idea poses several new problemsconcerningthe networkingaspects. In fact, the ¿things¿ composing the IoT will be characterized by low resources in terms of both computation and energy capacity. Accordingly, the proposed solutions need to payspecial attentionto resourceef ciencybesides the obviousscalability problems. The papers included in this volume present a picture of the current state of the art on the above issues; more speci cally, concepts and ideas are discussed on n- working, middleware, security and privacy, RFID and sensor networks, as well as electromagnetic aspects.
