Abstract: To deal with the challenges of the distributed collaborative processing of battlefield information caused by the dynamic communication environment, a mathematical model is established for the unstable communication quality and working conditions. On this basis, a collaborative information processing model is proposed to improve the timeliness of information processing under the premise of ensuring the reliability of information processing. Finally, a highly effective and timeliness collaborative information processing algorithm is proposed. A series of comparison experiments are designed to verify the performance of the algorithm, the simulation results show that the algorithm has excellent performance in reliability and timeliness, and can effectively support the construction of information systems in complex battlefield environment.
