英文摘要：

The model of sensor network is the key technology in the whole sensor network monitoring system, which impact on network costs and performance directly. At present, researchers gave several sensor network models, but these models had poor practicality and very high cost in practical project. This paper presented a compensation algorithm which based on virtual sensor and actual monitoring of environmental characteristics, inspired by the soft sensors and used mathematical analysis. It improved this method that the performance of the sensor network was well and reduced the network cost largely. Experiments show that this method is of high practical value.
