隨著無線通訊技術越來越進步加上硬體設備價錢低廉，無線網路早已悄悄得融入在我們的生活當中，使得人們可以利用無線通訊設備，像是手機、平板電腦及筆記型電腦等，在任何時間及地點都能與路邊設施（RSU）來作連結，並且透過網路來進行資料的上傳下載，大大的提高生活的便利性。近年來，車載隨意網路(Vehicular Ad-Hoc Network，VANETs)的議題，逐漸被關注，而許多各大車廠（BMW，Ford等），紛紛把隨時隨地上網的概念延伸至車載隨意網路上，透過在車上裝置無線設備，讓用路人也能隨時從網路上傳或下載資料。
由於車載隨意網路中，車輛移動的速度快，導致拓譜結構變化大以及車輛與車輛之間路徑的連結容易中斷。然而在路邊架設路邊設施能緩解此一問題，但是由於建置及維護大量的路邊設施的成本相當昂貴，如果只建置少量的路邊設施，可能導致通訊範圍無法涵蓋整條道路，因此如何減少成本來拉長通訊的時間，則具有相當的挑戰性。在本論文中，為了要解決此一問題，我們提出了路邊停車作為路邊設施的概念，並且透過合作式的資料傳輸，來改善現有的問題。

With the advances in wireless communications technology and affordable hardware, wireless networks have already crept into our daily lives such that people can use wireless communication devices (e.g. mobile phones, tablet PCs and notebook computers) to connect to the Roadside Unit (RSU) at any time and place. Through the network for uploading and downloading data, convenience is greatly improved. In recent years, VANETs (Vehicular Ad-Hoc Networks) issues have gained attention. Many major automobile companies (BMW, Ford, etc.) have extended the concept of accessibility anytime and anywhere to VANETs, so that users on the road can also upload or download information from the Internet through wireless devices in the vehicle unit.

In VANETs, the fast moving of vehicle results in topology changes and connection path break between the vehicle and the vehicle. Although the set up of RSUs can alleviate this problem, the installation and maintenance cost is very high. Furthermore, if only a small number of RSUs are built, this may result in a communication range not covering the entire road, Therefore, reducing expenses while lengthening communication time is substantial challenge. In this paper, we apply roadside parking cars and propose collaborative data transmission to solve this problem.
