摘要
车辆自组织网络中网络拓扑的高动态性及节点的高速移动会导致路径频繁断裂。针对该问题,提出一种基于稳定路径的路由协议。利用节点的移动信息预测链路的使用寿命连结失效时间(LET),通过同方向行驶的节点组建链路,并选用最大LET的链路构建路径,使路径趋于稳定,同时减少控制开销。仿真结果表明,与DSR算法相比,该路由协议能增强路由稳定性,提高网络吞吐量。
In Vehicle Ad hoc Networks（VANET）, due to its characteristic with high dynamic topology and high-speed mobile, the path frequently ruptures. Therefore, route algorithm based on stable path is proposed. The mobile information of node is used to predict the Link Expiration Time（LET） and link is discovered by the same direction nodes. The most LET is considered to build the path, which makes path stable. Furthermore, control overhead is reduced. Simulation results show that the stability of routing is enhanced and throughput is improved in the proposed route scheme.
