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, […]


SRA A Sensing Radius Adaptation Mechanism for Maximizing Network Lifetime in WSNs

SRA: A Sensing Radius Adaptation Mechanism for Maximizing Network Lifetime in WSNs Abstract Coverage is an important issue that has been widely discussed in wireless sensor networks (WSNs). However, it is still a big challenge to achieve both purposes of full coverage and energy balance. This paper considers the area coverage problem for a WSN where each […]
