Data Transmission with Reduced Delay for Distributed Acoustic Sensors
International Journal of Distributed Sensor Networks, 2015 This paper proposes a channel access control scheme fit to dense acoustic sensor nodes in a sensor network, where multiple acoustic sensor nodes within communication range of a cluster head are grouped into clusters.

A Low-Cost Robust Distributed Linearly Constrained Beamformer for Wireless Acoustic Sensor Networks With Arbitrary Topology [PDF]
IEEE/ACM Transactions on Audio Speech and Language Processing, 2017 We propose a new robust distributed linearly constrained beamformer that utilizes a set of linear equality constraints to reduce the cross power spectral density matrix to a block-diagonal form. The proposed beamformer has a convenient objective function
