中文摘要：

多媒体传感器网络能够采集和传输信息丰富的音频、视频、图像等多媒体信息,具有十分广泛的应用前景,是近年来无线传感器网络的研究热点。目前,国外多媒体传感器节点主要针对图像传输;国内使用的节点大多都难以满足多媒体信息处理和传输等方面的应用要求。本文针对鄱阳湖鸟类声音监测的应用,设计实现了一种新型的高性能多媒体传感器节点。实验结果表明,由该节点组成的多媒体传感器网络,能有效建立路由,实时地感知和采集网络覆盖区域内的多媒体信息。

英文摘要：

The Multimedia WSN,which mainly focuses on sampling and collecting rich information such as audio, video and image, is a new kind of application mode of sensor network. It has very wide application prospect and has become research hotspot recent years. At present, multimedia sensor nodes from abroad are always expensive and narrowly targeted, while the design of domestic sensor nodes can not satisfy the high requirements of processing performance and RF bandwidth in Multimedia WSN. In this paper, we designed and implemented a new type of high-performance multimedia sensor node for birds＂ twitter monitor at Poyang lake. Experiment results prove that network composed of such nodes, can build routing effec- tively, sense and collect multimedia information in real-time.
