Summary:
The real-time requirements of network communication in cyber-physical systems are high, and the network topology is complex, which makes the communication efficiency in the system low in real-time. However, the traditional routing algorithm has been unable to adapt to the increasingly complex intelligent communication network in today's society. In order to improve the network communication efficiency of the cyber-physical system, a cyber-physical fusion system overlay network construction method based on an improved variable neighborhood search algorithm is proposed. Reduce the communication time overhead of cyber-physical systems. In the network node selection method of the cyber physical system, the neighborhood structure and the dithering method of the variable neighborhood search algorithm are optimized. The objective function is used to further optimize the selection strategy of the covering node set. Finally, the network time cost, communication delay and algorithm stability of the proposed method are analyzed on a large number of random discrete node sets. The experimental results show that the optimized variable domain search algorithm can effectively reduce the network delay and time overhead, and improve the communication efficiency of the cyber-physical system.
