一种多优先级的自适应太赫兹无线局域网定向MAC协议
A Multi-priority Adaptive Terahertz Directional MAC Protocol for Wireless LANs
摘要
Abstract
In order to address the problems of insufficient priority for transmission of important information and collision of time slot request frames in terahertz directional wireless local area network(WLAN),a multi-priority adaptive terahertz WLAN directional medium access control(MAC)protocol,priority-based adaptive time slot request MAC(PA-MAC),is proposed.The PA-MAC protocol adopts a priority division mechanism based on the type of data service,and different priority nodes are given different avoidance window sizes to ensure that important information is transmitted first;it adopts a new type of contention access period(CAP)time slot division mechanism based on the priority,which reduces the probability of collision;and it adopts a node state-based adaptive application time slot mechanism,which improves time slot utilization.Compared with the existing protocols,the PA-MAC protocol enables the nodes to apply for more remaining time slot resources,which increases the time slot utilization rate by 5.89%,the network throughput by 5.86%,and the data transmission success rate by 6.23%.关键词
