This SpringerBrief offers fresh advances within the cognitive MAC designs for opportunistic spectrum entry (OSA) networks. It covers the fundamental MAC functionalities and MAC improvements of IEEE 802.11. Later chapters talk about the present MAC protocols for OSA and classify them in accordance with attribute features.

The authors offer new learn in adaptive service sensing-based MAC designs adapted for OSA, which optimize spectrum usage and confirm a calm coexistence of authorized and unlicensed structures. Analytically devised through optimization and game-theoretic methods, those adaptive MAC designs are proven to successfully lessen collisions among either basic and secondary community users.

Researchers and pros operating in instant communications and networks will locate this content material invaluable. This short can also be an invaluable research consultant for advanced-level scholars in desktop technological know-how and electric engineering.

Example text

Therefore SP uses TDMA for streaming and real time applications sensitive to jitter and delay while CBAP based on CSMA/CA is used for bursty traffic such as internet browsing. TDMA allocates some time-slots in the SP fields to some STAs where they wake up on these fixed time intervals to transmit and receive information. This is also beneficial since TDMA can be used for directional communication using beamforming while CSMA/CA can only operate in omni-directional transmission and reception mode [3, 14].

Furthermore, in an ad-hoc OSA network, there is a need for a fully distributed random-access-based MAC design with the cooperative behavior for SUs. These observations motivate us to study the distributed random-access-based MAC design and present the performance analysis in a multi-user OSA network, considering the effect of random returns of PUs and contention among SUs. Recent advances in cognitive MAC designs for an OSA network in [49–52] will be covered intensively in this Springer Brief. References 1.
