Optimization Algorithms for UAV-and-MUV Cooperative Data Collection in Wireless Sensor Networks

open access: yesDrones, 2023
The deployment of unmanned aerial vehicles (UAVs) has significantly improved the efficiency of data collection for wireless sensor networks (WSNs). The freshness of collected information from sensors can be measured by the age of information (AoI), which

Metamodeling and development of information systems

open access: yesAgricultural 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,

Optimizing age of information with correlated sources

open access: yesProceedings of the Twenty-Third International Symposium on Theory, Algorithmic Foundations, and Protocol Design for Mobile Networks and Mobile Computing, 2022
We develop a simple model for the timely monitoring of correlated sources over a wireless network. Using this model, we study how to optimize weighted-sum average Age of Information (AoI) in the presence of correlation. First, we discuss how to find optimal stationary randomized policies and show that they are at-most a factor of two away from optimal ...

Age of information: The gamma awakening [PDF]

open access: yes2016 IEEE International Symposium on Information Theory (ISIT), 2016
We consider a scenario where a monitor is interested in being up to date with respect to the status of some system which is not directly accessible to this monitor. However, we assume a source node has access to the status and can send status updates as packets to the monitor through a communication system.

Patient information comes of age [PDF]

open access: yesHealth Information & Libraries Journal, 2013
AbstractThis virtual issue (VI) has been assembled to coincide with the 8th Annual Patient Information Conference 2013 organised by the UK Patient Information Forum (PiF). The conference theme ‘Information and support – a service in its own right’ is a response to policy documents and initiatives in both Scotland and England which signal the coming of ...

The age of information in gossip networks [PDF]

open access: yes, 2013
We introduce models of gossip based communication networks in which each node is simultaneously a sensor, a relay and a user of information. We model the status of ages of information between nodes as a discrete time Markov chain.

Age-Aware Utility Maximization in Relay-Assisted Wireless Powered Communication Networks

open access: yesEntropy, 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 ...
