Abstract: In order to solve the networked intelligent sensor system load balance problem and improve service response speed, a load balance realization method based on Probabilistic Preferred Grey Markov Chain Prediction (PP-GMCP) algorithm is proposed. This method real-time monitors Network Capable Application Processor (NCAP) load status, combines residual correction and grey Markov chain prediction, effectively predicts NCAP load capacity. A load balance simulation platform based on OPNET is constructed to validate algorithm performance. The test shows that the PP-GMCP algorithm effectively improves the service request processing speed, compared to weighted round robin and least connection scheduling its average service response delay reduces 11.1 and 25.1%, respectively, the NCAP load fluctuation range is the smallest and obtains better load balance effect.
