A New Sensor Antenna-array Selecting Method in Wireless Sensor Networks

In this paper, a novel selecting method based on Hopfield neural networks (HNN) is proposed, which is used to select the sensor nodes as the antenna-array in the sensor networks. In our method, we select the sensor nodes, which have the lowest cost and also satisfy the distance requirement of the multi-input-multi-output (MIMO) system, to act as multiple transmitting and receiving antennas. Using the HNN for selecting makes it feasible and easy to realize. Simulation results also indicate the effectiveness of the proposed method
