The Age of Information: Real-Time Status Updating by Multiple Sources [PDF]
IEEE Transactions on Information Theory, 2016 We examine multiple independent sources providing status updates to a monitor through simple queues. We formulate an age of information (AoI) timeliness metric and derive a general result for the AoI that is applicable to a wide variety of multiple ...

Age-of-information in the presence of error [PDF]
2016 IEEE International Symposium on Information Theory (ISIT), 2016 We consider the peak age-of-information (PAoI) in an M/M/1 queueing system with packet delivery error, i.e., update packets can get lost during transmissions to their destination. We focus on two types of policies, one is to adopt Last-Come-First-Served (LCFS) scheduling, and the other is to utilize retransmissions, i.e., keep transmitting the most ...

Scheduling Policies for Minimizing Age of Information in Broadcast Wireless Networks [PDF]
IEEE/ACM Transactions on Networking, 2018 In this paper, we consider a wireless broadcast network with a base station sending time-sensitive information to a number of clients through unreliable channels.

Age-of-Information Dependent Random Access for Massive IoT Networks [PDF]
Conference on Computer Communications Workshops, 2020 As the most well-known application of the Internet of Things (IoT), remote monitoring is now pervasive. In these monitoring applications, information usually has a higher value when it is fresher.

Optimizing age of information with correlated sources
Proceedings 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 ...

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,

On the Age of Information in Status Update Systems With Packet Management [PDF]
IEEE Transactions on Information Theory, 2015 We consider a communication system in which status updates arrive at a source node, and should be transmitted through a network to the intended destination node. The status updates are samples of a random process under observation, transmitted as packets,
