Transport mechanism for streaming media in wireless network
一种适用于无线网络的流媒体传输机制

A novel transport protocol Wireless Multimedia Transport Congestion Control (WMTCC) to was presented to improve the performance of streaming media transmission over wireless networks. The proposed protocol can distinguish packet loss due to network congestion from packet loss due to wireless link error by sending probing packets. In this way the sender can get the accurate state of the networks and adjust the transmission rate appropriately to maintain the Quality of Service (QoS) of the streaming media services. Due to the accurate distinguishing of the packet loss between network congestion and wireless link error, the protocol can maintain high throughput even with high bit error rate. The simulation results show that the new protocol can get higher throughput and larger congestion window in wireless networks and performs consistently better than other existing mechanisms.
