    摘要: Network quality of VANET (Vehicular Ad-hoc Network) is usually bad due to high mobility, speed variation, driver behavior, traffic density, swarm effect, environment complexity, etc. All these factors frequently change the car-to-car distance resulting in intermittent network disconnection. When disconnection occurs, rebuild routing path will increase transmission time and consume transmission bandwidth. Since the network topology of VANET usually deployed along the roadside, the nearby cars are usually the best candidates to help relay packets. In this paper, we propose a Cookie-Cooperative Automatic Repeat reQues (CCARQ) method to enhance network performance by repairing intermittent broken connections. CCARQ is able to assist in transmission in Network Layer through MAC layer enhancement. Simulations show that CCARQ outperforms both AODV and Bypass-AODV in packet delivery ratio, end-to-end delay, control overhead and goodput.
