Cooperative MIMO, energy efficiency, MIMO,
An energy-efficient virtual multiple-input multipleoutput
(MIMO)-based communication architecture is proposed
for distributed and cooperative wireless sensor networks. Assuming
a space-time block coding (STBC) based MIMO system,
the energy and delay efficiencies of the proposed scheme are
derived using semi-analytic techniques. The dependence of these
efficiency values on physical channel propagation parameters,
fading coherence time and the amount of required training is
also investigated. The results show that with judicious choice of
design parameters the virtual MIMO technique can be made
to provide significant energy and delay efficiencies, even after
allowing for additional training overheads.
