Operational information content sum capacity: From theory to practice

This paper considers Quality-of-Information (QoI) aware resource allocation policies for multiuser networks. QoI is a recently introduced composite metric which is impacted by a number of attributes of information communicated from the source(s) to the destination(s), and as such differs from traditional quality-of-service metrics considered to date. The focus of this work is defining the Operational Information Content Sum Capacity (OICC-S) of a network, achieved by the set of information attributes supported that maximize sum quality of the network. This quality is defined as a function of the information attributes provided by the source input, as well as the channel induced attributes that impact the QoI delivered to the destination(s). Optimum rate allocation to maximize the output sum quality of information and achieve OICC-S of the network for various settings is provided, and demonstrated to differ from the solution that provides maximum throughput, making QoI-awareness necessary in resource allocation. Insights arising from the analysis are provided, along with those from practical scenarios.

本文考虑多用户网络中具有信息质量（QoI）感知的资源分配策略。信息质量是最近引入的一种综合指标，它受到从源到目的地所传递信息的多个属性的影响，因此不同于迄今为止所考虑的传统服务质量指标。这项工作的重点是定义网络的操作信息内容总和容量（OICC - S），它是通过支持的一组信息属性来实现的，这些属性使网络的总质量最大化。这种质量被定义为源输入所提供的信息属性以及影响传递到目的地的信息质量的信道诱导属性的函数。提供了在各种设置下使信息输出总质量最大化并实现网络的OICC - S的最优速率分配，并证明它不同于提供最大吞吐量的解决方案，这使得在资源分配中具有信息质量感知是必要的。文中还提供了从分析中得出的见解以及从实际场景中得出的见解。
