Vehicular ad hoc networks (VANETs) recently covered a wide range of intelligent transportation systems (ITSs) and applications.VANETs consist of convinced unique characteristics such as dynamic movement and high speed.Due to these characteristics, link failures occur, and delay and routing overhead is greatly increased, directly affecting the effectiveness, Quality of Service (QoS), and stability of VANETs.To achieve an efficient and reliable network performance, this paper proposes QoS Aware Hybrid Optimization f…
