Wireless sensor networks (WSN) are multi-element systems with complex functions and behavior. WSN have many uses in scientific, medical, commercial and military. Examples of these applications include environmental monitoring, smart homes and offices, surveillance, intelligent transportation systems, and many others. To successfully build and run the wireless sensor network need to address challenges related to energy saving, media access control, organization of individual elements in clusters and connections between clusters, routing of packet information, distribution of computing power. All of these tasks sensor network must decide on their own, which means that from the point of view of the consumer fulfillment of the principle of «unfolded, plug and play». Therefore, networkы must have the adaptive properties and are often seen as self-organizing systems, in the sense of the term borrowed from the synergetics. The article analyzes a set of properties WSN and shown to be more appropriate for them is the paradigm of complex adaptive systems. The specificity of wireless sensor systems, using as an information carrier UWB signals is investigated. It is found that in such networks, all other things being equal, it is easier to solve collision problem, they eliminate less power and use less power, each element of UWB network is more clearly delineated range than narrowband nodes. In UWB network virtually no interference, which greatly simplifies the task of care and maintenance if you change the units, including by reconfiguring the structure of the system. In UWB network there is no interference, which greatly simplifies the task of care and maintenance if you change the units positions, including by reconfiguring the structure of the system.
