Abstract :
Energy efficiency is one of the most critical concerns for wireless sensor networks (WSNs). A novel virtual multiple input multiple output (MIMO) communication scheme with feedback channel is proposed in WSNs in this paper. Using the feedback channel, channel state information (CSI) could be returned to transmit cluster. Then the ldquobetterrdquo node could be selected to participate in cooperation. Simulation results show the effectiveness of the proposed algorithm in energy saving.
