Metamodeling and development of information systems
Agricultural Economics (AGRICECON), 2004 Metamodeling is becaming an important part of information systems development. When metamodeling we are working with metamodel which define the syntax and the semantics of models. There are a lot of standards for definition of metamodel e.g. COMMA, GOPRR,

Not Just Age but Age and Quality of Information [PDF]
IEEE Journal on Selected Areas in Communications, 2021 A versatile scheduling problem to model a three-way tradeoff between delay/age, distortion, and energy is considered. The considered problem called the age and quality of information (AQI) is to select which packets to transmit at each time slot to minimize a linear combination of the distortion cost, the age/delay cost and the energy transmission cost

Age-Aware Utility Maximization in Relay-Assisted Wireless Powered Communication Networks
Entropy, 2021 This article investigates a relay-assisted wireless powered communication network (WPCN), where the access point (AP) inspires the auxiliary nodes to participate together in charging the sensor, and then the sensor uses its harvested energy to send ...

Minimizing the Age of Information in Wireless Networks with Stochastic Arrivals [PDF]
IEEE Transactions on Mobile Computing, 2019 We consider a wireless network with a base station serving multiple traffic streams to different destinations. Packets from each stream arrive to the base station according to a stochastic process and are enqueued in a separate (per stream) queue.

Average Age of Information in Wireless Powered Relay Aided Communication Network
IEEE Internet of Things Journal, 2022 In order to satisfy timeliness requirements arising from environmental sensing applications, Age of Information (AoI) was proposed to characterize the freshness of the received updates.

Using Timeliness in Tracking Infections
Entropy, 2022 We consider real-time timely tracking of infection status (e.g., COVID-19) of individuals in a population. In this work, a health care provider wants to detect both infected people and people who have recovered from the disease as quickly as possible. In

Version Age of Information in Clustered Gossip Networks [PDF]
IEEE Journal on Selected Areas in Information Theory, 2021 We consider a network consisting of a single source and $n$ receiver nodes that are grouped into equal-sized clusters. Each cluster corresponds to a distinct community such that nodes that belong to different communities cannot exchange information. We

On the Potential of Enhancing Delay-Tolerant Routing Protocols via Age of Information
Future Internet, 2022 In this paper, we study the potential of using the metric of Age of Information (AoI) for enhancing delay-tolerant routing protocols. The latter have been proposed for alleviating the impact of long roundtrip time in networks operating in harsh ...

On the Value of Information in Status Update Systems
Entropy, 2022 The age of information (AoI) is now well established as a metric that measures the freshness of information delivered to a receiver from a source that generates status updates.
