CSMA/CA MAC Protocol with Function of Monitoring based on Binary Tree Conflict Resolution for Cognitive Radio Networks

摘要

The CSMA/CA protocol is the most widely-compete agreement used by a network. Therefore, MAC layer of cognitive radio networks mostly use the CSMA/CA protocol to provide the competitive channel resources. Due to the unique characteristics and related needs of the cognitive radio networks, design their network protocol is a critical task. For its characteristics, design and implement a comprehensive CSMA/CA protocol, including arrival rate control, priority services, monitoring, conflict resolution and increased throughput; elaborated protocol model, system throughput and other parameters, demonstrates the correctness of the CSMA/CA protocol; comparison with other protocols, highlighting the advantages of the agreement.
