In recent years, wireless communication demands from high-speed vehicles rapidly increase, due to the enrichment of various vehicular applications. Such high demands result in a compelling burden on the supporting infrastructure in vehicular networks, which in turn deteriorate the quality of experience (QoE) of vehicular users. In-device caching/storage has been attracting increasing research interests, which can significantly alleviate the burden of the wireless infrastructure and enhance the network throughput via spatial frequency reuse. However, its realization in vehicular scenarios is significantly hindered by the high mobility of vehicles. To cope with such issue, we propose a relay-and-repair based in-vehicle storage (R2 IVS) system with two storage maintaining mechanisms, namely the storage relay and the storage repair, to account for the vehicle mobility and vehicle-to-vehicle (V2V) communications vulnerability. The proposed R2 IVS scheme is evaluated in a general vehicular network setting based on a microscopic stochastic vehicle mobility model combined with the classic Markov chain model of IEEE 802.11p media access control (MAC) function. Theoretical analysis and simulation results demonstrate the superiority of our proposed R2 IVS system compared with the one directly fetching contents from wireless infrastructure.
