In this paper, we focus on fairness issues of Vehicle-to-Infrastructure (V2I) communications. In particular, we show that under a common technique of selection of RSUs by OBUs based on the received signal strength, a vast variability of a number of OBUs connected to RSUs can be observed leading to inefficient/unfair service provided by RSUs. To overcome this problem, we propose an algorithm for RSU selection called RSEL to obtain even attachment of OBUs to RSUs. Its objective is to approach the best solution in terms of minimizing variability of the number of OBUs connected to each RSU and, as a result, increase fairness of access to services in V2I communications. We analyzed five scenarios referring to different RSU location schemes for two VANET topologies: considering urban environment and a multilane highway. As confirmed via simulations, the average fairness of RSU load (based on Jain's formula) was improved up to 50%, while the value of user-perspective fairness measure of collision-free transmissions, introduced in this paper, was increased up to 35%.
