EU-funded researchers developed smart wireless technology that efficiently manages radio-frequency spectrum resources and avoids transmission bottlenecks. The new system, which also prevents selfish attacks by secondary users, could be used in military and commercial wireless applications.
The growing popularity of wireless networks has highlighted the need to increase network capacity and efficiency. Cognitive radio-based networks have attracted increased attention and have been studied in depth to overcome the problem of spectrum scarcity in next-generation wireless communication systems.
