摘要

当前车载无线接入(WAVE)系统的介质访问控制(MAC)协议没有考虑CCH和SCH的时间利用率。本文提出了一种新的扩展MAC协议的机制，该机制根据车辆密度和网络负载情况动态调整控制信道(CCH)和业务信道(SCH)间隔的长度。在提出的机制中，每辆车利用信标评估CCH中的接收概率，然后相应地调整CCH间隔的持续时间。这使车辆能够处理交通负载条件，并为安全应用提供可靠高效的数据传输，以确保人身安全，同时为非安全应用保留时间。

An extension to IEEE 1609.4 for dynamic multichannel interval adjustment in WAVE architecture

The current Medium Access Control (MAC) protocol of the Wireless Access in Vehicular Environments (WAVE) system does not consider time utilization of CCH and SCH. In this paper, we present a novel mechanism to extend MAC protocol, which dynamically adjusts the length of Control Channel (CCH) and Service Channel (SCH) intervals according to vehicle density and load conditions of network. In the proposed mechanism, each vehicle makes use of the beacons to evaluate reception probability in CCH then adjusts duration of CCH interval accordingly. This enables vehicles to handle traffic load conditions and provides reliable and efficient data transmission for safety applications to ensure human safety while maintaining time for non-safety applications.
