Offline Learning for Acknowledgment Optimization in Massive LoRaWAN Networks
Internet Technology Letters, Volume 8, Issue 6, November/December 2025.ABSTRACT LoRaWAN faces critical limitations in large‐scale deployments due to spectrum contention, duty‐cycle restrictions, and energy constraints. These challenges impact the reliability and responsiveness of bidirectional communication particularly when conventional acknowledgment mechanisms are used.

On retrial queues with controlled input flow [PDF]
, 2009 Дослiджуються марковськi системи з повторними викликами i керованою iнтенсивнiстю вхiдного потоку. Для моделей такого типу знайденi умови iснування стацiонарного режиму, одержанi явнi формули та ефективнi алгоритми розрахунку стацiонарних iмовiрностей ...

MathematicsInspired by call centers, this paper models them as a constant retrial queue, with feedback and delayed vacations to balance high efficiency and low cost for service agents. After completing the service, the server randomly waits for an idle period.

Analysis of Markov multiserver retrial queues with negative arrivals [PDF]
, 2001 Negative arrivals are used as a control mechanism in many telecommunication and computer networks. In the paper we analyze multiserver retrial queues; i.e., any customer finding all servers busy upon arrival must leave the service area and re-apply for ...

Standard and retrial queueing systems: a comparative analysis [PDF]
, 2002 We describe main models and results of a new branch of the queueing theory, theory of retrial queues, which is characterized by the following basic assumption: a customer who cannot get service (due to finite capacity of the system, balking, impatience ...

Performance Analysis of Two Different Types of Waiting Queues with Working Vacations
Journal of MathematicsThis work examines a new class of working vacation queueing models that contain regular (original) and retrial waiting queues. Upon arrival, a customer either starts their service instantly if the server is available, or they join the regular queue if ...

Retrial queues with variable rate of input flow [PDF]
, 2013 Розглянуто системи з повторними викликами типу MQ / M / m / ∞ зі змінною інтенсивністю вхідного потоку, для яких знайдено умову існування стаціонарного режиму. Для розрахунку стаціонарних ймовірностей використано метод апроксимації.
