Abstract

In order to make two independently operated terahertz wireless LANs quickly complete coordinated convergence and improve the performance of the converged network, this paper proposed an efficient and fast convergence of MAC protocols(EFC-MAC). Firstly, in view of the imperfection of the existing bridge node election mechanism and the shortcomings of the network coordination and convergence mechanism, this paper proposed a mechanism to start the election of bridge nodes when the first network node applied for network access, and announced the election results in the BP period of the next superframe, and other mechanism to decide whether to apply for CTA to forward heartbeat messages according to whether the network had completed coordinated convergence. So that the network could complete convergence efficiently and quickly. Then, aiming at the problem that the application method of public time slots by network nodes are not flexible enough, this paper proposed a mechanism to dynamically apply for CTA according to the amount of time slot remaining in P-CTAP, which improved the performance of the network. Finally, aiming at the problem that the bridge node switching mechanism is not clear, this paper proposed a mechanism to complete the bridge node switching by using a CAP period length. Simulation results show that the proposed protocol can effectively improve network throughput, improve slot utilization and reduce data transmission delay.
