Özet

This paper aims to increase downlink utilization by effectively scheduling roadside unit (RSU) to clustered Vehicular Ad-hoc Network (VANET) communications. It is assumed that each vehicle of the cluster has its own data to be downloaded from RSU which can be acquired by both RSU to vehicle (R2V) and RSU to vehicle to vehicle (R2V2V) communications. Proposed model converts resource sharing problem between R2V2V and R2V communications to a linear programming problem. Simulations demonstrated that the proposed model utilizes downlink better than earliest deadline based and first come first served based scheduling algorithms.
