- Abstract
- In the future smart cities, connected vehicles provide various infotainment and nonsafety services using vehicle to vehicle and vehicle to road side units (RSUs) communications. To enable these infotainment services, content providers cache their popular data on the RSU storage to make it quickly accessible for the vehicles. In this article, we propose a novel content caching protocol used by mobile network operators. The proposed protocol uses knapsack optimization algorithm to allocate the variable-sized contents to the RSUs based on their utility. Results show that the proposed protocol provides 13% and 70% approximately higher download data than the market matching and random caching, respectively. © 2021 John Wiley & Sons, Ltd.
