【摘要】：車輛間通信(Vehicle-to-Vehicle,V2V)是車載自組織網(wǎng)絡(luò)(Vehicular Ad Hoc Networks,VANET)的主要通信方式之一。然而,車輛快速移動、網(wǎng)絡(luò)拓?fù)浣Y(jié)構(gòu)的不斷變化,以及障礙物等其他問題的存在使得車輛之間的通信鏈路是不可靠的,且效率非常低�；谖恢玫穆酚蓞f(xié)議比較適合動態(tài)變化的V2V通信。但是,由于缺乏對道路段連通性和道路拓?fù)渥兓膶?shí)時感知,所選擇的路由可能只是局部最優(yōu),車輛的快速移動使得通信鏈路頻繁斷開,并且沒有考慮不同業(yè)務(wù)對QoS的要求。本文針對上述問題,首先介紹了V2V通信以及相關(guān)的路由協(xié)議,并著重介紹了基于位置的路由協(xié)議,介紹了基于位置的路由協(xié)議的國內(nèi)外相關(guān)研究以及目前仍然存在的一些問題。然后,針對這些問題,研究了V2V切換管理的關(guān)鍵技術(shù),提出了一種改進(jìn)的貪婪周邊無狀態(tài)路由(Greedy Perimeter Stateless Routing,GPSR)協(xié)議,即感知移動性的地理路由協(xié)議(Mobility-aware Greedy Perimeter Stateless Routing,MA-GPSR)。MA-GPSR協(xié)議提出的道路之間的切換方案聚焦于道路信息收集機(jī)制和道路評估方案,分析了道路段通信鏈路的斷開時機(jī),并在道路段鏈路不通時及時切換至通信質(zhì)量更好的道路段。另一方面,提出了一跳之間的切換,把移動性信息分為四類,通過對移動性信息的感知處理,判斷切換的時機(jī),并根據(jù)不同業(yè)務(wù)類型的QoS需求和距離選擇最優(yōu)的切換目標(biāo)車輛切換來保證通信的持續(xù)性和高效性。最后,對MA-GPSR協(xié)議與現(xiàn)有改進(jìn)的基于位置的路由協(xié)議進(jìn)行了仿真分析,結(jié)果表明,MA-GPSR性能優(yōu)于其他基于位置的路由協(xié)議,能夠適應(yīng)動態(tài)變化的V2V通信。
[Abstract]:Vehicle-to-vehicle communication (V2V) is one of the main communication methods of vehicular Ad Hoc Networks (VANET). However, with the rapid movement of vehicles, the network topology is constantly changing. And other problems such as obstacles make the communication link between vehicles unreliable and inefficient. Location-based routing protocol is more suitable for dynamic V2V communication. Due to the lack of real-time awareness of road segment connectivity and road topology changes, the route chosen may be only locally optimal, and the rapid movement of vehicles leads to frequent disconnection of communication links. In this paper, the V2V communication and related routing protocols are introduced firstly, and the location-based routing protocols are emphasized. This paper introduces the research of location-based routing protocols at home and abroad and some problems that still exist at present. Then, the key technologies of V2V handoff management are studied. In this paper, an improved greedy Perimeter Stateless routing protocol is proposed, that is, the Mobility-aware Greedy Perimeter Stateless routing protocol proposed by the Mobility-aware Greedy Perimeter Stateless routing MA-GPSR.MA-GPSR protocol focuses on the road information collection mechanism and the road evaluation scheme. This paper analyzes the disconnection time of the road segment communication link, and switches to the road segment with better communication quality in time when the road segment link does not work. On the other hand, the one-hop switching is proposed, which divides the mobility information into four categories. Based on the perception of mobility information, the timing of handoff is judged, and the optimal handoff target vehicle handoff is selected according to the QoS requirements and distances of different traffic types to ensure the continuity and efficiency of communication. Simulation results show that MA-GPSR protocol is superior to other location-based routing protocols and can adapt to dynamic V2V communication.
