摘要：Ensuring high saturated throughput of SCHs and reducing the transmission delay of service packets on CCHs are one of the most challenging issues in multichannel operations IEEE 1609.4 standard. Moreover, multiple issues due to its highly dynamic topology, the high mobility, the change trajectory, and Nakagami propagation channel caused by Additive White Gaussian Noise (AWGN) are challenges in assuring the Quality of Service (QoS) in multichannel operations IEEE 1609.4 standard. In this paper, we propose a coordination scheme based on the multichannel operations IEEE 1609.4 standard, in terms to enhance the Quality of Service (QoS) caused by different dynamic topology, high mobility, change trajectory, and Nakagami propagation channel caused by Additive White Gaussian Noise (AWGN). The propose scheme is enhancement of the previous scheme, i.e. Variable CCH Interval (VCI). We use ns 3.18 and Matlab tools for the simulation and evaluation of the performance. From the simulation, we found that the proposed scheme enhance the saturated throughput and reduces the transmission delay of service packets compared the previous scheme. This paper also evaluates the proposed scheme caused by different mobility models. We also analysis probability of the signal error Nakagami-m distribution parameters caused by the existence of the Additive White Gaussian Noise (AWGN).
