Analysis of a simplified gated polling scheduling model based on clustering routing

Proposed a Simplified Gated control strategy for polling scheduling mechanism of clustering algorithm in WSN. A corresponding analytical model was established according to the embedded Markov chain theory to analyze the Simplified Gated service polling system in discrete time. Through the establishment of probability generating function for center transfer access in polling moment, accurately analyzed average queue length, average cycle time and average waiting delay of information frame of the system. The research of polling control mechanism with Simplified Gated service and experimental performance analysis under different parameters showed that the polling scheduling model was more effective in the application of WSN based on clustering control strategy.
