英文摘要: Wireless Multimedia Sensor Network (WMSN) is recently emerging as an extension to traditional scalar wireless sensor network, with the distinctive features of sensing rich multimedia content such as audio, images, video and requiring capability for massive data transmission. The multimedia streaming is sensitive to Quality of Service (QoS) parameters, such as delay, delay jitter, bandwidth and so on. How to provide QoS support for the multimedia streaming applications is the key to the practical application of WMSN. Research of QoS-aware WMSN transmission control protocol is developed by using the theory of network coding and fuzzy logic. Firstly, WMSN QoS multi-path routing protocol based on network coding and fuzzy logic is studied, and an energy-aware clustering algorithm based on fuzzy logic is designed, to form clustering network topology. A QoS routing selection algorithm based on fuzzy logic is proposed, which optimizes the multi-path routing selection. And the network coding based multi-path routing model is established, which is used to analyze the energy and transmission performance of WMSN. Secondly, QoS-aware multi-path congestion control mechanism is investigated by combining the theory of network coding, QoS multi-objective optimization and congestion control. To settle the congestion problem of mu
