Abstract: To solve the problem that the communication delay widely exists in distributed sensor network, this paper develops the original asynchronous track fusion algorithm and proposes a new asynchronous track fusion algorithm based on network delay. The algorithm can simulate communication delay. Besides, it can automatically track and examine the sensors which have delay and take corresponding actions. The new algorithm provides higher adaptability and practicability. The impact of the data transmission delay is analyzed and the effect of delay is compared through simulation.
