Study on Adaptive QoS Solution of Real-time Video Stream in Wireless Network
With the rapid development of wireless network technology,wireless networks have been widely used in many fields due to the flexibility of wireless access.However,in the field of video transmission,because the link state is instability and the transmission is easily interfered in wireless networks,the quality of video transmission is affected badly.In fading and shadowing channels,some users cant watch the video normally.This paper provides an adaptive QoS solution of real-time video stream in wireless network,by adding a relay server it can provide multicast or unicast video stream satisfying multiple QoS for users with different network state.This solution has been successfully applied in Qingdao Public safety emergency video surveillance system.
