This SpringerBrief presents recent advances in the cognitive MAC designs
for opportunistic spectrum access (OSA) networks. It covers the basic
MAC functionalities and MAC enhancements of IEEE 802.11. Later chapters
discuss the existing MAC protocols for OSA and classify them based on
characteristic features.
The authors provide new research in adaptive carrier sensing-based MAC
designs tailored for OSA, which optimize spectrum utilization and ensure
a peaceful coexistence of licensed and unlicensed systems. Analytically
devised via optimization and game-theoretic approaches, these adaptive
MAC designs are shown to effectively reduce collisions between both
primary and secondary network users.
Researchers and professionals working in wireless communications and
networks will find this content valuable. This brief is also a useful
study guide for advanced-level students in computer science and
electrical engineering.
