Abstract:

To the characteristics of decentralized deployment of the command, control, communications, computers, intelligence, surveillance and reconnaissance (C4ISR) services, limited computing/storage resources for combat platforms, and high requirements for evolutionary real-time performance, the overall architecture of distributed monitoring and evolution of system state is designed based on hierarchical structure, and a dynamic adjustment method of service deployment scheme hierarchy is proposed. By analyzing the implementation difficulties of the resource coordination module in the overall architecture, the distributed deployment model of the C4ISR service is demonstrated based on defining the evolution cost and information flow path length. To the characteristics that the service deployment location and information flow path are included in the evolution scheme, a pair of exchange ideas, shortest path planning method and m-best strategy are combined to propose a greedy solution algorithm to realize the rapid generation of evolution scheme. The experimental results show that the method can effectively control the evolution range while ensuring the efficiency of system information flow, and can be suitable for the agile adjustment of service deployment method in the process of task execution.

Key words: system status monitoring, dynamic adjustment of service deployment scheme, hierarchical structure, pair-wise exchange method, path planning, evolution cost constraint
