A QoS Communication Scheme for Video Surveillance in Wireless Mesh Network

Aiming at the inherent defects of mesh network routing algorithm, this paper proposes a QoS communication scheme based on improved ant colony algorithm(ACO). Our strategy is mainly for streaming media file transmission in video surveillance, such as H.264 and MP4, to provide QoS for transmission in wireless network. We also improve the routing model of wireless network based on ant colony from data structure change and pheromone update, so that it can forward data packets more stably and efficiently. Then the network test results are sorted out and analyzed. Finally, the simulation results show that the proposed scheme can better meet the QoS indicators of traffic flow transmission, and the system can complete the expected video monitoring function in real environment.
