Wireless Access in Vehicular Environment (WAVE) 為 IEEE 802.11p 車載通訊系統的標準。當 WAVE 實作在高密度之 vehicular Ad-Hoc Networks (VANETs) 時可能會降低整體效能，特別是碰撞發生時，會產生封包遺失及封包延遲。因此，我們引入了 Time Division Multiple Access (TDMA) 方法來改善整體效能，但在高密度流量、車輛之高移動性與網路拓樸動態的改變情況下，TDMA 排程很難去進行管理。本篇論文提出在 VANETs 下根據 traffic priority 來做 TDMA 的分群。群組是根據 traffic priority 的高、低進行分類，並將此資訊加入至 TDMA MAC Header 中。透過 NS3 模擬的結果顯示，我們提出此方法在高密度節點的情況下有良好的表現

The IEEE 802.11p is a standard in a vehicular communication system, known as Wireless Access in Vehicular Environment (WAVE). An implementation of that standard as the MAC Protocol in a high-density of nodes in Vehicular Ad-Hoc Networks (VANETs) may create a performance drawback, in particular for packet loss and delay whenever collisions happened. Introducing Time Division Multiple Access (TDMA) schemes can improve the performance. However, TDMA scheduling is difficult to manage in the case of high-density of traffic, the high mobility of vehicles, and dynamic network topology. This thesis proposes a clustered-based TDMA by traffic priority in VANETs. The clustered traffic is defined as high and low traffic priority and embedded in TDMA MAC Header. The evaluation result obtained through NS3 Simulator shows that the proposed approach performed better in a high-density of nodes.
