Abstract
Long Term Evolution (LTE) is the new generation of infrastructure-based wireless technologies that can be used for vehicular communications, and already a standard considered as the preliminary version of 4G mobile communications. It provides a cellular networks-based solution, generally called vehicle to infrastructure (V2I), for vehicular safety applications. In this work, we evaluate the performance of different downlink scheduling strategies under various urban and rural scenarios, in which voice, video and safety data traffic coexist. The traffic safety application scenarios we consider are variations of collision avoidance using LTE-based broadcast communication. Our main evaluation criteria are delay and packet loss rate. We present our findings for each scenario and compare the results.Keywords
