development of intelligent transport systems (ITS). Today, ITS is not just about connected cars on the road, but also about the fully automated intelligent vehicle. Many emerging vehicle-to-everything (V2X) applications such as collision warning, traffic management, platooning, remote vehicle control, cooperative driving and autonomous driving are already in the implementation or development phase. The new IEEE 802.11bd working group (TGbd) was recently formed to explore the future roadmap for V2X and is currently working on a new standard called Next Generation V2X (NGV). NGV is expected to target broader future applications that require higher throughput and operate in a high mobility environment with an extended communication range. Cross-Layer design is an emerging solution to support new NGV applications. In this thesis, we propose a new PHY\/MAC\/NET cross-layer architecture to improve the performance of NGV applications. We begin this research by identifying improvements to the PHY and MAC layers of other IEEE 802.11 Wi-Fi standards that could be adopted for the 802.11bd standard. Then, we propose a first original contribution, namely, a PHY\/MAC\/NET cross-layer architecture to improve the performance of NGV applications in a high mobility environment. Simulation results show that our solution achieves twice the throughput at the MAC layer in an environment with a relative speed between vehicles of up to 500 km\/h, as required by the NGV standard. However, throughput performance degrades in dense VANETs due to the MAC layer blocking problem. To solve this problem, we propose a second cross-layer contribution based on the selection of transmitting antennas and the adaptation of the transmitted power. The results obtained show that this design allows more vehicles to communicate simultaneously and considerably improves the average network throughput, particularly for high-density VANETs.<\/p>\n<h5>Abstract:<\/h5>\n<p>Vehicular communication, or vehicular ad hoc networks (VANETs), is a wireless vehicular network technology that can support the development of intelligent transportation systems (ITS). Nowadays, ITS is not only about connected cars on the road, but also about the fully automated intelligent vehicle.

NGV is expected to target broader future applications that require higher throughput and operate in a high mobility environment with extended communication range. Cross-Layer design is an emerging solution to support new NGV applications. Thus, in this thesis, we propose a new cross-layer PHY\/MAC\/NET architecture to improve the performance of NGV applications. We begin this research by identifying PHY and MAC layer enhancements of other IEEE 802.11 Wi-Fi standards that could be adopted for the 802.11bd standard. Then, we propose a first novel contribution, namely, a cross-layer PHY\/MAC\/NET architecture to improve the performance of NGV applications in a high mobility environment.

Nevertheless, the throughput performance degrades in dense VANETs due to the blocking problem in the MAC layer. To solve this problem, we propose a second cross-layer contribution based on the selection of transmitting antennas and the adaptation of the transmitted power. The results show that this design allows more vehicles to communicate simultaneously and significantly improves the average network throughput, especially for high density VANETs.<\/p>\n<\/div><\/section>","protected":false},"excerpt":{"rendered":"","protected":false},"author":20,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[317],"tags":[],"class_list":["post-55516","post","type-post","status-publish","format-standard","hentry","category-these-2021"],"_links":{"self":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/55516","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/users\/20"}],"replies":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/comments?post=55516"}],"version-history":[{"count":0,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/55516\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/media?parent=55516"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/categories?post=55516"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/tags?post=55516"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
