There are three important concepts that have gained relevance over the past years. First, the concept of classic embedded systems where the focus is on the control of physical processes (machinery, automobiles, planes, etc.). Second, the notion of pervasive computing (or ubiquitous computing) which foresees everyday objects having some form of computation capacity and, in most cases, sensing and communication facilities. Third, wireless sensor networks where small computing devices are able to sense their environment and cooperate in order to achieve a common goal. We refer to the unified vision of these three systems as networks of Cooperating Objects (COs). This new vision is more powerful and has a larger scope than each of the individual system concepts out of which it evolved. The vision of Cooperating Objects is, therefore, quite new and needs to be understood in more detail and probably extended with inputs from the relevant individual communities that compose it. Building on the success of the previous CONET/Ubicitec workshops, UBICITEC 2014 aims at providing a forum to discuss the similarities, complementariness and advances of the areas mentioned above in order to integrate them into single coherent systems.
