Abstract
Wireless Multimedia Sensor Networks (WMSNs) is inherited and developed from the traditional Wireless Sensor Networks (WSNs). Quality of service (QoS) has become an important index to evaluate the quality of the WMSNs. This paper discusses the following two aspects. Firstly, we propose a method to h andle sudden network congestion–improving the way of key frame transmission, namely increasing the compression ratio of the key frames. The process reduces the video image quality, it can guarantee the continuity of video signal and conform the requirement of people’s daily viewing. Secondly, the paper is discussing to apply the Ant Colony Optimization (ACO) to improve the mathematical model and make it apply to WMSNs. At last, the experiment turns out that the improved ACO can be used in routing and this has certain application value.
