Sensor selection for source extraction in heterogeneous wireless sensor networks
Hongbin Chen, Jiuchao Feng, Chi Kong Tse · International Journal of Communication Systems · 2009
Abstract A sensor selection scheme for source extraction in heterogeneous wireless sensor networks is proposed. The proposed scheme selects the sensors corresponding to the reconstructed mixtures with the largest signal‐to‐noise‐ratios to transmit their data to a fusion center. It exploits the heterogeneity of the sensor observations and reduces the amount of transmissions. The results demonstrate that the proposed scheme outperforms the full utilization scheme and the random selection scheme. Copyright © 2009 John Wiley & Sons, Ltd.
