Abstract
With the increasing in demand for video traffic, video service has been becoming more and more diversified. Scaled video coding (SVC) has become one of the most common video code technology to meet the requirements of different video service types. Therefore, SVC based video users quality of service (QoS) guarantee is one of the most basic problems of the network, but there are few studies focusing on the SVC based video users QoS guarantee protocol for the next generation wireless location access network (WLAN). This paper proposes SVC based media access control (MAC) protocol with QoS guarantee for next generation WLAN, referred to as QoS-SVC. If there are some residual sub-channels resource after the first channel contention, the protocol offers another opportunity, named second random contention, for the video users both collided and successful in the first random contention phase and enables them to transmit their data in the residual sub-channels. The simulation results show that the throughput adopting QoS-SVC is improved by 154%, compared with non-second random contention access (Non-SRCA) protocol.
