Abstract:	近年來車輛的安全應用成為車載網路中重要的議題，如何透過多躍散佈緊急訊息成為了一個主要的課題。本篇論文我們設計一個十字路口緊急訊息廣播協定，透過蒐集傳輸者鄰居訊號強度資訊，並藉由訊號強度分析出個車輛訊號強度資訊，並透過車輛資訊達到動態區域切割，找出最佳的車輛做緊急訊息代傳，藉此避免廣播風暴的發生以及減少多躍散佈所耗費之時間。本論文重點在於安全訊息廣播，時間將會為重要參考因素，透過模擬分析來驗證本篇論文提出之廣播協議，在傳輸延遲以及傳輸成功率會有顯著的改善。 In recent years, vehicle safety application has played a more important role in Vehicle Ad-hoc NETwork (VANET). How to disseminate emergency message in a Multi-hop way becomes a major issue. In this paper, we propose an intersection emergency message broadcasting protocol. To do so can not only find the best vehicle in the furthest possible segment to relay the emergency messages in the network, but also can avoid broadcast storms and reduce end-to-end delay of the packet. This paper focuses on safety messages broadcast time. Through simulation analysis to validate the proposed broadcast protocol, significant improvements are available in the transmission delay and transmission success rates.
