Aiming at problem of stability and reliability guarantee of multi-sensor network system

use energy constrained fault detection technology

through balance nonlinear system resources and improve efficiency of fault detection and detection precision. Meanwhile

combine multi-sensor system resources and application requirements

fault balanced weighting parameter is obtained by calculation

extract fault feature and mapping

then establish optimal troubleshooting plan decision-making mechanism through multi-objective constraints.Experimental results show that the proposed algorithm is superior to traditional fault detection algorithm

failed node positioning is accurate

detection is efficient. On the other hand

when troubleshooting

nonlinear optimization decisions is able to reduce energy consumption

effectively guarantee robustness of multi-sensor system.
