针对用户高质量决策和高效率行动对信息的需求,从战场信息链流程角度提出了面向价值的战场信息处理和分发网络框架,采用信息质量来表征用户信息需求,并通过用户信息需求满意度指数来表征通信系统所分发的信息对用户完成任务的价值。依据信息质量和用户信息需求来评估信息处理所得到信息的价值,设计面向价值的贪心调度算法进行信息分发,使网络中传输的数据是富有价值的信息流。最后通过战场目标跟踪应用场景进行仿真实验,验证了面向价值的信息分发相对于基于服务质量的分发方式,在资源利用率和用户满意度上的性能优势,尤其在带宽资源缺乏的情况下,性能优势更为显著。
For the information requirements to high quality decision-making and efficient operations,the value-oriented battlefield information processing and distribution framework based on the process of battlefield information chain was proposed,while characterized the user information needs by quality of information(QoI),and characterized the value of the information which distributed by the communication system for user to complete the task by the user information re-quirements satisfy degree index.The value of information(VoI) was assessed which obtained from the information proc-essing according with information quality and user information requirements,and designing the value of greed scheduling algorithm for information dissemination,so that the network transmission of data is valuable information flow.Finally,the simulation experiments were made which based on the object tracking scenario in the military environment to verify the VoI-based distribution compared to the QoS-based distribution methods,the result shows that the resources utilization and user satisfaction for the VoI approach are advantage,especially in the case of the bandwidth resources is lacked.
