The Storage System Design for Dynamic Data of Internet of Vehicles Based on B+ Tree Technology

摘要

With the explosion of automobile information, the industry of internet of vehicles (IOV) is rising rapidly, and the vehicle number in IOV is growing exponentially; however, this results in problems like how to store and analyze the massive dynamic data of IOV. Considering the IOV's characteristics like different data types, uncertain sampling period, and huge size, the study presented in the paper designs an efficient data saving and analysis storage system based on B+ tree technology. The storage system can customize the file type, file path, search keywords, saving data fields, and according to the data features in IOV, the storage system can customize B+ tree's index key dimension to enhance the search efficiency. Theoretical analysis and practical test results show that the storage system can solve the problems of traditional database in IOV application, such as large physical space, slow querying speed, the difficulty of data backup, and frequent data loss.
