| Popis: | This paper presents the design and analysis of directional random access MAC protocols for cognitive radio wireless mesh network (CRWMN). We have proposed three directional random access MAC protocols for CRWMNs using three different access mechanisms called Directional CSMA/CA MAC protocols for Cognitive Radio (DCR-MAC). An event driven simulator is used to make performance comparison for the three MAC protocols. Moreover, the performances of the DCR-MAC protocol for the three access mechanisms are also compared with an omni-directional CRMAC protocol in terms of average throughput and average packet delay. The performances of the proposed directional protocols show better performance for CRWMN. |
