基于最优方案VANET协议的研究

由于网络拓扑结构频繁变化，节点之间物理物理距离超过通信距离时，消息不能转发，信息没有及时更新。目前市场销售的大部分导航软件一般采用的是最短路径策略或最少收费策略，这种方式在一般情况下能够满足人们的某一出行要求，但对于当前交通路况拥堵的情况下，这几种策略显然是行不通的，最短路径或最少收费的方式不仅不能给使用者节省时间，还可能降低了出行的效率。这种方式以远远不能满足人们出行的需求，如何保障即尽可能选择最短路径又能够保证通信的畅通，是本论文研究的方向。

Based on the research of the optimal scheme VANET protocol

Due to the network topology changes frequendy, physical physical distance over communication distance between nodes, the message cannot be forwarded, information is not updated in a timely manner. Sale of most of the navigation software generally USES the market at present is the shortest path strategy or a minimum charge, in this way usually can satisfy people＇s a travel request, but for the current under the condition of road traffic congestion, this several strategies obviously doesn＇t work, the shortest path or minimum charge way not only can＇t give users save time, may also reduce the efficiency of travel. This way to far cannot satisfy the needs of people travel, how to ensure that as far as possible to choose the shortest path and to ensure smooth communication is the direction of this thesis research.
