Abstract: Named data networks have natural advantages in the application of the Internet of Things. However, some of its characteristics at the beginning of its design hindered its application in the Internet of Things. Therefore, academia proposes to add a middleware at the network level and application level to increase the support ability of named data network (NDN) for multi-dimensional data. Based on this idea, this paper took Internet of vehicles as scenario to validate the validity of middleware and its supporting algorithms, and propose improvement measures for the defects of relevant mechanisms. Through experimental simulation, the performance of the name translation optimization algorithm and the improved mechanism are analyzed. The experimental results show that the optimization algorithm and improvement mechanism effectively improved the performance of NDN in dealing with multi-dimensional data requests.
