摘 要: 多媒体传感器网络面临用有限能量传输大量数据的挑战,因此本文提出一种多媒体传感器网络中的分布式图像压缩传输算法,用普通节点协同压缩图像,簇头消除不同节点发来图像数据的相关性,进行去相关图像传输。仿真结果表明,该方法减少了传输图像的数据量,节省了网络能耗,具有一定的实用价值。 Multimedia sensor networks are faced with the challenge of transmitting a large amount of data with limited energy resources.A distributed image compression-transmission algorithm is proposed in this paper.Ordinary nodes and compress images collaborate with each other.The cluster head transmits information after eliminating correlation of images which are sent by different notes.Simulation results show that this method can reduce the amount of transmitted image data and save network energy consumption,which may be more practical.
