近年來，在汽車的數量快速的增長同時也提高了對車輛之間移動通訊的需求。 因此，在這個情況下，已經提出了一種用於汽車的新型自組織網路，稱為車載隨意行動網絡 (VANET)。 這個新型的自組織網路能夠有效的提高交通運輸和便利性，同時也使駕駛更安全。另一方面，車輛自組織網絡的要求不僅要滿足節點的快速變化和兼顧穩定性，還要兼顧延遲時間、網絡頻寬、網絡負載……等問題。因此，在考慮通訊品質並提供便利和安全的駕駛環境的同時，還要確保車輛網絡中有最佳路徑是需要進一步研究的方向。由於車載隨意行動網絡的路由協議極其複雜，迄今為止，大部分相關研究都集中在該主題上。車輛行駛速度快，網絡拓撲變化頻繁，實際行駛中車輛的移動性可能會導致車輛位置識別不正確，導致傳輸質量不佳，導致數據包傳遞失敗或傳輸延遲增加。如何解決上述問題是論文的重點。
本研究主要探討了 VANET 中使用的眾所周知的地理路由協議 (GPSR) 的一種改善，通過讓源節點向拓撲的多條路徑發送連續數據包來引入一些多條路徑的功能，因為在傳輸過程中僅使用一條路徑可能會導致接收失敗。由於同一路徑中的擁塞和飽和導致的延遲。所以我們的提議確定為 H-GPRS 可以提供延遲的解決方案。我們使用真實視頻剪輯在有障礙物的城市 VANET 中評估後者，以證明 H-GPSR 用於真實視頻的可行性。我們的實驗結果表明我們的建議能夠克服觀察到的問題並提高傳統GPSR 的性能。

Vehicle Ad Hoc Networks are designed to improve the safety and security of road users by sending traffic conditions and other information to the vehicles. Many routing protocols have been suggested for deployment of these networks. The main goal of Vehicle Ad Hoc Networks (VANET) is to improve the traffic safety, the vehicles can send effective traffic information and road conditions. Global navigation has been extensively researched in recent years as a viable option for Vehicle Ad Hoc Networks (VANET), the main reason is that there are wireless networks and services all over the world. A navigation system is required to enable the establishment of a website in VANET. The performance of the system is often an issue that VANET administrators face. The algorithm must be designed to keep up with the changes in the environment. It should also be able to respond efficiently to the needs of different applications.
This article discusses an improvement of the well-known geographic routing protocol (GPSR) used in VANET, which introduces some multi-path functions by letting the source node send continuous data packets to multiple paths in the topology, because only one path is used in the transmission process. The path may cause reception. Delay due to congestion and saturation in the same path. Therefore, our proposal determines that H-GPRS can provide a delay solution. Our experimental results show that our proposal can overcome the observed problems and improve the performance of traditional GPSR.
