Large amount of information like text, audio and video exists in vehicular ad hoc networks (VANETs). However, the highly dynamic network feature and the limited memory of the local server pose challenges to resource management, leading to the failure of resource presentations for users, moveover the transmission of the invalid fragment data would also result in the significant waste of the precious bandwidth and memory. To solve this problem, this paper proposes an improved fuzzy logic resource management (FLRM)-multi-parameter fuzzy logic resource management (MP-FLRM). In this scheme, we firstly gather and record the request time, download time and upload time for each resource by the designed vehicle to infrastructure (V2I) communication mode. Then survival time can be reached after defuzzifier of multi-parameters thus, used for updating the resource list in real time. Simulation results show that MP-FLRM will improve the system throughput, accordingly, enhancing the system performance.
