Cognitive systems
Cognitive systems are used to adapt the operating system to the changing environment. This can be accomplished by many methods suggested in this chapter, and many additional methods will be available in the future. The optimal cognitive system solution evaluates a system's available capabilities as well as all of the available knowledge about the changing environment, and then it calculates, makes trade-offs, and determines the best solution for the system to adapt to these environmental changes with minimal impact to performance. In addition, the cognitive system contains a learning capability that uses past experiences and impact/results of changes and uses this information to make smart decisions in the future. Game theory has been used to establish cognitive networks, and selfish nodes are eliminated by cooperation and establishing a Nash equilibrium. Although there are challenges with cognitive systems, they are beginning to infiltrate our current technologies, and they produce optimal communications and network systems.
