Interconnection and self-organized systems are normally populated with heterogeneous and different devices. The differences range from computational capabilities, storage size, etc. Instead of considering the heterogeneity as a limitation, it is possible to "turn it"as a primitive control of the system, in order to realize more robust and more resilient communication systems. Based on these premises, we identify specific situations, where mobile nodes with a plethora of interesting features and sensing capacities, can be exploited by configuring them in such a way to make them playing different roles in respect of them for which they have been initially conceived [4] . The differentiated use of devices, together with a careful analysis of the characteristics and performance requirements of the current and the future networks, allow the adaptation to the exponential growth in demand for high bandwidth applications [26] . This is exactly the philosophy embraced in [28] , where Software Defined Radio (SDR) and Cognitive Radio (CR) have been considered and analyzed in a novel context, namely body networked systems. A detailed analysis of body systems as networked systems has also been considered in [6] and [14] . In [6] a novel communication paradigm, namely a molecular communication, has been considered to show how a nanoparticulate system can be suitable to coexist in a biological environment. An experimental analysis to asses the theoretical assumption has been developed in [14] . In order to asses new/alternative communication paradigms, there is the necessity from one side to consider and analyze the specific context and its level of interaction with the communication system and on the other side the correct identification of the specific features of the communication paradigm itself. This type of analysis allowed the design and implementation of an acoustic communication approach [29] , where the ultrasound represent the wave carriers of data information. This "unusual" transmission means has been selected as the most suitable in a context as the body, where the aqueous environment makes it not suitable for more "traditional" communication paradigms, e.g. the one based on Radio Frequency (RF) waves.
