  This work presents joint minimum mean-square error (MMSE) consensus algorithm
and relay selection algorithms for distributed beamforming. We propose joint
MMSE consensus relay and selection schemes with a total power constraint and
local communications among the relays for a network with cooperating sensors.
We also devise greedy relay selection algorithms based on the MMSE consensus
approach that optimize the network performance. Simulation results show that
the proposed scheme and algorithms outperform existing techniques for
distributed beamforming.
