摘要: 
在這個車輛越來越多車速越來越快的時代,以往傳統的MANET已快要跟不上車輛節點變換的速度,車載資通訊 (Telematics) 儼然成為一個重要的通訊手段,而VANET正是逐漸發展起來的車上通訊系統。本篇論文著重在將VANET加入拓撲控制來達到較少的成員變動,並且防止因車輛過多而造成資訊洪流(information flooding) 的發生;我們利用兩個方法的篩選來選出成員:首先為利用角度的演算法,可以快速的將大量節點排除,以免造成過多的資訊交換而造成資訊洪流;接下來為利用距離訊息的演算法,可以將出入群組過於迅速的節點排除,以達到穩定的拓撲。最後我們利用4種在不同道路或不同的收發車輛移動方式的模擬,來與沒有拓撲控制之網路做效能比較。模擬實驗結果證實所提出之方法具可行性。

In a vehicular ad-hoc network, the topology may change frequently. Thus we want to find a way to reduce the frequent changes, and organize nodes effectively. To solve this problem, some trade-offs are made. The key design issue is how to make the topology stable quickly. This paper focuses on distributed topology control in order to reduce the rate of group member change, and avoid the unnecessary information exchange. Two methods are sequentially applied to choose the group members of each node: the first method is based on the concept of the cone-based method, which can exclude a lot of nodes quickly; the second method is based on the concept of the time-slot method, which can stabilize the network topology. The simulation results show that the proposed scheme can achieve effective topology management under certain scenarios.
