Cooperative MIMO technique is considered as one of the new solutions to minimize the energy consumption in wireless sensor networks.Considering the circuit energy consumption,we propose a multi-hop cooperative V-BLAST transmission scheme coupled with cross-layer design.In our design,the transmission rate,the number of clusters,the number of cooperative nodes and the number of hops are jointly optimized.Simulation results show significant energy savings and lifetime maximization of the network with judicious choice of network parameters.
