The emergence of applications in vehicles requires computational capability which poses a major challenge in mo-bile edge computing. In this paper, we have proposed the token-based predictive offloading scheme with the aim of providing the optimal cost of offloading and reducing the average delay. Specifically, the proposed scheme uses a token-based approach for offloading the data from vehicles to MEC(Mobile Edge Computing) server. We have designed a separate table for MEC servers to show the status of consumed tokens and available tokens and another table for vehicles to store the status for another vehicle for vehicle to vehicle (V 2 V) communication. Dedicated Short Range Service (DSRC) technology is used to facilitate the communication between vehicle to vehicle and vehicle to infrastructure(e.g.toll gate). Extensive simulations are conducted in highway scenarios and the results demonstrate the superiority of this offloading scheme. The proposed scheme achieves low delay performance and decreased computation cost over other competing schemes in typical urban and highway scenarios.
