How to Measure the Average and Peak Age of Information in Real Networks? (2019)
Presentation / Conference Contribution
Barakat, B., Yassine, H., Keates, S., Wassell, I., & Arshad, K. (2019, May). How to Measure the Average and Peak Age of Information in Real Networks?. Presented at European Wireless 2019, Aarhus, Denmark

The Age of information (AoI) was proposed in the literature to quantify the freshness of information. The majority of the work done in this area has theoretically evaluated AoI and its Peak (PAoI). In this paper, a method for obtaining the value of A... Read More about How to Measure the Average and Peak Age of Information in Real Networks?.

Modelling IoT devices communication employing representative operation modes to reveal traffic generation characteristics (2019)
Journal Article
Barakat, B., Keates, S., Wassell, I. J., & Arshad, K. (2021). Modelling IoT devices communication employing representative operation modes to reveal traffic generation characteristics. International Journal of Parallel, Emergent and Distributed Systems, 3

Several traffic models for the Internet of Things (IoT) have been proposed in the literature. However, they can be considered as heuristic models since they only reflect the stochastic characteristic of the generated traffic. In this paper, we propos...

Adaptive Status Arrivals Policy (ASAP) Delivering Fresh Information (Minimise Peak Age) in Real World Scenarios (2019)
Presentation / Conference Contribution
Barakat, B., Keates, S., Wassell, I., & Arshad, K. (2019, July). Adaptive Status Arrivals Policy (ASAP) Delivering Fresh Information (Minimise Peak Age) in Real World Scenarios. Presented at HCII: International Conference on Human-Computer Interaction, Or

Real-time systems make their decisions based on information communicated from sensors. Consequently, delivering information in a timely manner is critical to such systems. In this paper, a policy for delivering fresh information (or minimising the Pe...

Is the Zero-Wait Policy Always Optimum for Information Freshness (Peak Age) or Throughput? (2019)
Journal Article
Barakat, B., Keates, S., Wassell, I., & Arshad, K. (2019). Is the Zero-Wait Policy Always Optimum for Information Freshness (Peak Age) or Throughput?. IEEE Communications Letters, 23(6), 987-990. https://doi.org/10.1109/LCOMM.2019.2907935

The Zero-Wait (ZW) policy is widely held to achieve maximum information 'freshness', i.e., to achieve minimum Peak Age (PA) and maximum throughput, for real-time Internet-of-Things applications. In this paper, it was shown through a series of experim... Read More about Is the Zero-Wait Policy Always Optimum for Information Freshness (Peak Age) or Throughput?.

Deriving Machine to Machine (M2M) Traffic Model from Communication Model (2019)
Presentation / Conference Contribution
Barakat, B., Keates, S., Arshad, K., & Wassell, I. J. (2019). Deriving Machine to Machine (M2M) Traffic Model from Communication Model. In The Fifth International Symposium on Innovation in Information and Communication Technology (ISIICT 2018) (27-31).

The typical traffic models proposed in literature can be considered as heuristic models since they only reflect the stochastic characteristic of the generated traffic. In this paper, we propose a model for M2M communications that generates the traffi... Read More about Deriving Machine to Machine (M2M) Traffic Model from Communication Model.
