Compressive Sensing-Based Data Aggregation Approaches for Dynamic WSNs.
IEEE Communications Letters(2019)
摘要
Among various data aggregation approaches proposed for wireless sensor networks (WSNs), the one based on compressive sensing (CS) has the merit of low traffic cost. The key step to design a CS-based data aggregation protocol is to construct a measurement matrix Φ based on the network structure and to assign each node a unique column vector of Φ. Assuming an expanded scenario, where some new nodes ...
