Abstract

This article comprehensively surveys the area of age of information (AoI) in the wireless networks and focuses on categorising and reviewing the current progress on AoI from an optimisation perspective. We first present the multiple definitions of AoI and its variants. Then, we give an overview of AoI-optimal sampling policies and packet management strategies from data source. We also summarise the work of minimising AoI in the case of resource-constraint source nodes, such as energy harvesting and UAV-assited sampling. We provide a summary of many kinds of scheduling policies for efficiently managing the use of resources in different network settings, which consist of various data sources and servers. In addition, we discuss some other applications focusing on the optimisation of AoI. Finally, we explore the performance of those policies in practical implementation and some potential future directions on AoI research.

无线网络信息时代优化研究
本文全面调查了无线网络中的信息时代(AoI)领域,并从优化的角度对AoI的当前进展进行了分类和回顾。我们首先介绍了AoI及其变体的多种定义。然后,我们从数据源的角度概述了aoi最优采样策略和数据包管理策略。我们还总结了在资源约束源节点(如能量收集和无人机辅助采样)的情况下最小化AoI的工作。我们总结了多种调度策略,以有效地管理不同网络设置(由各种数据源和服务器组成)中资源的使用。此外,我们还讨论了一些专注于AoI优化的其他应用。最后,我们探讨了这些政策在实际实施中的表现以及未来AoI研究的一些潜在方向。

期刊介绍: Web services are providing declarative interfaces to services offered by systems on the Internet, including messaging protocols, standard interfaces, directory services, as well as security layers, for efficient/effective business application integration. Grid computing has emerged as a global platform to support organisations for coordinated sharing of distributed data, applications, and processes. It has also started to leverage web services to define standard interfaces for business services. IJWGS addresses web and grid service technology, emphasising issues of architecture, implementation, and standardisation.
