基于语义的网络智能系统通信

Semantics-Empowered Communication for Networked Intelligent Systems

Marios Kountouris, Nikolaos Pappas

摘要:

传统上,无线连接被认为是一个不透明的数据管道,承载消息,其上下文相关的意义和有效性被忽视。然而,在新兴的网络物理和自主网络系统中,获取、处理和发送过量的分布式实时数据,这些数据最终对最终用户来说是陈旧的或无用的,这将导致通信瓶颈、延迟增加和安全问题。我们设想一个通信范式的转变,这使得信息的语义,即,信息对于数据交换目标的重要性和有用性,是整个通信过程的基础。这需要一个面向目标的统一的信息生成,传输和使用,考虑到过程的动态性,信号稀疏性,数据相关性和语义信息属性。我们将这种结构上新的,协同的方法应用到通信场景中,目的地的任务是实时源重建远程驱动的目的。利用语义授权的采样和通信政策,我们表现出显着减少重建错误和成本的驱动错误,以及在生成的无信息样本的数量。

英文摘要:

Wireless connectivity has traditionally been regarded as an opaque data pipe carrying messages, whose context-dependent meaning and effectiveness have been ignored. Nevertheless, in emerging cyber-physical and autonomous networked systems, acquiring, processing, and sending excessive amounts of distributed real-time data, which ends up being stale or useless to the end user, will cause communication bottlenecks, increased latency, and safety issues. We envision a communication paradigm shift, which makes the Semantics of Information, i.e., the significance and the usefulness of messages with respect to the goal of data exchange, the underpinning of the entire communication process. This entails a goal-oriented unification of information generation, transmission, and usage, by taking into account process dynamics, signal sparsity, data correlation, and semantic information attributes. We apply this structurally new, synergetic approach to a communication scenario where the destination is tasked with real-time source reconstruction for the purpose of remote actuation. Capitalizing on semantics-empowered sampling and communication policies, we show significant reduction in both reconstruction error and cost of actuation error, as well as in the number of uninformative samples generated.
