車載隨意網絡路（VANET）乃是實現現代智慧運輸系統，確保道路交通安全，並提高道路運輸效率的關鍵致能技術之一。由於車輛具高移動性所導致之網路拓撲急劇變化，在車載隨意網路中找到可靠且穩定的路由雖極其重要卻也極具挑戰。近期有研究人員提出一個穩定路由決策方案，我們稱之為SRDS，此乃一位置感知﹙position-aware﹚需求式﹙on-demand﹚路由協定，其中並採用一種特定的基於距離的廣播方式。本文修改了SRDS之基於距離的廣播機制，使其具有更好的可達性﹙reachability﹚。模擬結果顯示，相較於原來的方法，所提機制顯著改善了路由發現的成功率。

The vehicular ad hoc network (VANET) is an essential enabling technology for the achievement of road traffic safety and efficiency in the modern intelligent transportation system. Reliable and stable routes are desirable but challenging in VANETs for their fast topology changes due to high mobility of vehicles. Recently a stable route decision scheme (SRDS), which is a position-aware on-demand routing protocol adopting a specific distance-based broadcasting method. In this thesis, a modified distance-based broadcasting mechanism with better reachability is proposed. Simulation results show that the proposed mechanism significantly improves success rate of route discovery compared with the original one.
