    Abstract: In order to improve the plug and play interface performance of networked intelligent sensors based on IEEE1451.5, performance optimization method of plug and play mechanism of ZigBee intelligent sensors based on periodic association matching communication (PAMC) was studied. The plug and play time was decreased and the identifying rate was improved through using simplified TEDS data structure. ZigBee optimization routing algorithm was proposed based on ZigBee neighbor table and node characteristic parameters, and optimal routing path was realized for wireless sensing data transmission. The experimental results show that the efficiency of data transmission and network real-timing are improved after optimization. The average hop count of data transmission and average delay are reduced by 42.9% and 28.1% respectively.
