Neighbor-Aided Spatial-Temporal Compressive Data Gathering in Wireless Sensor Networks
Neighbor-Aided Spatial-Temporal Compressive Data Gathering in Wireless Sensor Networks Abstract The integration between data collection methods in wireless sensor networks (WSNs) andcompressive sensing (CS) provides energy efficient paradigms. Single-dimensional CS approaches are inapplicable in spatial and temporal correlated WSNs while the Kronecker compressive sensing (KCS) model suffers performance degradation along with the increasing data dimensions. In this letter, aneighbor-aided compressive sensing (NACS) scheme is proposed for efficient data gathering in spatialand temporal correlated WSNs. During every sensing period, […]
