The Wireless Sensor Network(WSN) Compression Algorithm Based on Incremental Virtual Node

无线传感器传输过程是受能量限制的,除此之外,它的存储容量也是有限的。提出了一种基于渐进虚拟节点的小波数据压缩传输算法IVWC。由相应的簇头的实际存储容量来决定单轮传送数据的节点总数量,再由渐进虚拟节点对每轮收集的数据进行混合编码分析,最终实现渐进数据的节省存储空间传输。实验结果表明:所提出的算法在存储空间的节省上有很大的提高,比DIMENSIONS有更小的网络耗能和延时,并且具有存储有效性。

Research the energy storage optimization of wireless sensor. The paper puts forward a wireless sensor network wavelet compression algorithm based on incremental virtual node. Constructed sensing data scheduling rotation method. The corresponding cluster head determines the actual storage capacity single round total number of nodes transmit data, and then by gradual virtual nodes for each round of data collected hybrid coding, and the transfer of data to save storage space. The experimental results show that the proposed method can further save energy consumption and it is memory-effi-cient.
