Abstract

Networks for data transmission between objects of V2X intelligent transport systems are currently being actively developed. Most existing V2X networks operate based on the IEEE 802.11p standard. However, these networks can only provide basic V2X applications and are unable to meet the demands of today’s applications. As a result, the IEEE committee began developing a new IEEE 802.11bd standard. A significant innovation of this standard is the use of the channel bonding method, which allows data to be transmitted in several channels at once. One of the approaches that can significantly increase the efficiency of the channel bonding method is the correct selection of the contention window. In this paper, we propose an adaptive algorithm for selecting a contention window that is compatible with the channel bonding method, is easy to implement, does not require changes to existing devices, and takes into account the requirements for the quality of service of various types of traffic. Using simulation it is shown that the proposed algorithm increases the maximal allowable density of stations, at which the requirements for quality of service are still met, by 25% compared to the standardized solution.
