SEnsor Network for Dynamic and Opportunistic Radio Acess (SENDORA)
Start date: Jan 1, 2008, End date: Dec 31, 2010 PROJECT  FINISHED 

Dynamic spectrum allocation has become a key research activity in wireless communications field and in particular a key technology for "The Network of the Future" objective proposed in ICT Work Programme 2007.Following these current trends towards dynamic spectrum allocation, the SENDORA project will focus on developing innovative techniques based on sensor networks, that will support the coexistence of licensed and unlicensed wireless users in a same area. The SENDORA project ideas stem from recent fundamental works on cognitive radio technology.The capability to detect spectrum holes, without interfering with the primary network currently in use, is the actual major difficulty faced by the cognitive radio. The innovative concept proposed in SENDORA project consists in developing a "sensor network aided cognitive radio" technology which will allow to solve this issue, thanks to the introduction of sensor networks and associated networking capabilities.The sensor network aided cognitive radio proposed and studied in SENDORA project will address many different advanced techniques, but will also propose an analysis of the potential exploitation of these techniques. First, scenarios of interest will be defined and will provide the technical activities with requirements to cover. Different types of scenarios will be proposed, corresponding to real needs, mainly identified by the potential integrators of the solutions. On the technical point of view, novel spectrum sensing techniques will be first proposed to be able to identify spectrum holes. Corresponding information management and exploitation will be studied to achieve the co-existence of cognitive radios with primary licensed technology without generating harmful interferences. The design, dimensioning and networking of the wireless sensor network will be deeply addressed. Finally, a proof-of-concept demonstration will be developed to assess the theoretical research.
