Compressive sensing has been successfully used for optimized operations in wireless sensor networks. However, raw data collected by sensors may be neither originally sparse nor easily transformed into a sparse data representation. This paper addresses the problem of transforming source data collected by sensor nodes into a sparse representation with a few nonzero elements. Our contributions that address...
This paper proposes XOR-BiDO, a data delivery scheme (DDS) suited for multihop underwater acoustic networks characterized by regular bidirectional traffic streams. DDSs for multihop underwater networks usually assume a single-sink configuration, where most of the transmissions flow in a single direction. Throughput performance decreases and fairness suffers when such DDSs are subjected to heavy bidirectional...
