Abstract
The next generation of wireless networks is evolving towards networks of small, smart devices, which opportunistically share the spectrum with minimal coordination and infrastructure. This evolution is motivated by the technological advances in software defined radio (SDR) technology which promote high adaptability and flexibility for radio transmissions. The new emerging generation of networks consists of cognitive terminals, which intelligently and autonomously adapt to the channel environment to optimize their transmission parameters. In this chapter, we address the problem of designing and analyzing such networks, in the context of improving the overall network performance through cooperation. We discuss how the protocols run by these networks can be modeled as games, and what it takes to enforce cooperation in such scenarios. Our perspective is to take a fresh look at the design of upper layer protocols, and the interactions between them, in the context of enforcing cooperation for more efficient spectrum sharing. The questions we will address are related to the necessary protocol modifications to support cooperation, as well as to the viability of such cooperative network protocols.
