Abstract :
The paper proposes an effective adaptive p-persistent-based (APP) medium access control (MAC) scheme for WLAN-based dedicated short-range communications (DSRC) networks supporting multimedia services. The APP MAC scheme adaptively gives differentiated permission probabilities to on board units (OBUs) which are in different access category and with various waiting delay. Simulation results show that the APP MAC scheme can improve the performance of multimedia WLAN-based DSRC networks, such as small real-time packet dropping probability, low delay variation, and high system throughput, compared to conventional MAC algorithms
