Energy efficiency is the most important design goal
for wireless sensor networks (WSNs). In this paper, we propose
an energy-efficient cooperative MIMO scheme, which
combines energy-efficient LEACH (EE-LEACH) protocol and
cooperative MIMO. We name it as EE-LEACH-MIMO
scheme. EE-LEACH is an improved LEACH algorithm, in
which the network is partitioned to sectors with equal angle for
avoiding the distribution non-uniformity of cluster heads. In
EE-LEACH-MIMO scheme, the location and the residual
energy of each node are considered when the cluster heads for
clustering and cooperative nodes for MIMO system are chosen.
For comparisons, LEACH, EE-LEACH, the simple
cooperative scheme with LEACH and MIMO (LEACHMIMO),
and EE-LEACH-MIMO scheme are simulated. The
result shows that EE-LEACH-MIMO scheme can well balance
the network load, save energy and prolong the network
lifetime
