Distributed Compressed Sensing(DCS) is an effective means to reduce the amount of data transmission and energy consumption in Wireless Sensor Network(WSN). Hierarchical Distributed Compressed Sensing(HDCS) is proposed for clustering WSN. It eliminates the temporal-spatial redundancies among data collected by the cluster members with the intra-cluster DCS, and eliminates the spatial redundancies among clusters with the inter-cluster DCS. According to the signal's structured sparsity, a block-sparse intra-clu...
