Supporting multimedia services in wireless mesh networks is receiving more attention from the research community. While wired networks have mature infrastructure and protocols providing QoS for multimedia, supporting multimedia in multihop wireless mesh networks faces greater technical challenges. The unreliable nature and shared media of multihop communications make the deployment of multimedia applications in wireless mesh networks a difficult task. To identify and understand the issues and problems of providing multimedia in multihop wireless mesh networks, the researchers took video streaming as an example, setting up a real testbed to conduct extensive experiments in various scenarios and analyze its performance. In contrast to simulation or network-layer statistics based studies, the investigation is directly focused on video quality in multihop scenarios.
