In recent years, multimedia streaming has increased dramatically in wireless networks. Applications such as Video-on-Demand (VoD) and distributed file backup appear in Wireless Mesh Networks (WMNs). These applications have strict requirements for Quality of Service (QoS) with bandwidth guarantees. Streaming video flows over WMN faces some challenges as bandwidth guarantee; high data rate flows over a shared medium in a multi-hop manner can increase the packet loss and delay significantly. Real-time live surveillance applications do not usually use retransmission error control, video contents can be lost, and the quality of the video can be altered.
