    • A method is provided for efficiently transferring records related to places of interest between two communicating vehicles in a V2V system without initially having to transfer full text records. A determination is made as to whether information stored in a memory of the vehicle is redundant with the respect to the other vehicle. A query request is transmitted from a first vehicle to a second vehicle containing specifics as to what records the first vehicle is seeking. Data satisfying the query request represented by global unique index numbers is hashed to determine the similarity between the data of the two communicating vehicles. The similarity is used to determine whether a full filtered set of global unique index numbers should be transferred to the second vehicle for determining which records are not duplicate records. Thereafter, the second vehicle wirelessly transmits to the first vehicle the non-overlapping data that satisfies the query request.
    • 提供了一种用于在V2V系统中有效地传送与两个通信车辆之间的兴趣点相关的记录而不首先必须传送全文记录的方法。 确定存储在车辆的存储器中的信息是否相对于另一车辆是冗余的。 查询请求从第一车辆发送到第二车辆,该第二车辆包含关于第一车辆在寻找什么记录的细节。 满足由全局唯一索引号表示的查询请求的数据被散列以确定两个通信车辆的数据之间的相似性。 相似性用于确定是否应将完整过滤的全局唯一索引号码集合传送到第二车辆,以确定哪些记录不是重复记录。 此后,第二车辆向第一车辆无线地发送满足查询请求的非重叠数据。
