Analysis of classical retrial queue with differentiated vacation and state dependent arrival rate.
Ratio Mathematica, 2021 In present paper we have introduced the concept of differentiated vacations in a retrial queueing model with state dependent arrival rates of customers. The arrival rate of customers is different in various states of the server.

IET Smart Cities, Volume 8, Issue 1, January/December 2026.This paper presents an energy‐conscious, formally verified security protocol for low‐power medical and safety IoT devices operating in regulated environments. The protocol combines lightweight cryptography with formal verification and is validated through simulation and real‐world deployment across heterogeneous platforms.

Advances in Fuzzy Systems, Volume 2026, Issue 1, 2026.Wireless body area networks (WBANs) play a vital role in saving lives by accurately measuring physiological information in a cost‐effective manner. However, reliability and energy consumption remain major constraints in WBANs. Many researchers have claimed that transmission through relay nodes can mitigate these constraints.

AxiomsIn this article, we consider a make-to-stock queueing system with retrial customers. Upon their arrival, customers make a decision to either join the system or not based on a reward–cost function.

IEEE Access, 2019 In a cognitive radio (CR) system, excessive access services for secondary users (SUs) lead to a substantial increase in congestion and the retrial phenomenon, both of which degrade the performance of CR networks, especially in overload conditions.

Heterogeneous Finite-Source Retrial Queues [PDF]
Journal of Mathematical Sciences, 2004 The paper considers a system with \(K\) different sources of primary calls, each consisting of a single request. When source \(i\) is free at time \(t\) (i.e., is not being served and not waiting for serving), it may generate a primary call during interval \((t,t + dt)\) with probability \(\lambda _i dt + o(dt)\).

Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.This paper presents a new approach to determine the mean time to system failure (MTSF) and reliability function of k‐out‐of‐n systems with independent and identically distributed components following the inverse Weibull (IW) distribution. The system remains operational when at least k of its n components function properly.

Performance analysis of single server non-markovian retrial queue with working vacation and constant retrial policy [PDF]
, 2014 This paper analyses an M/G/1 retrial queue with working vacation and constant retrial policy. As soon as the system becomes empty, the server begins a working vacation. The server works with different service rates rather than completely stopping service

Journal of Applied Mathematics, Volume 2026, Issue 1, 2026.In this paper, a new generalized cost function construction for a single‐server multiphase queueing system with a Poisson input stream, hypoexponential‐k customer service time, and FIFO discipline is presented. A proposed relationship between service parameters in k phases is based on a geometric progression with rate α, 0 < α < 1.

Journal of Engineering, Volume 2026, Issue 1, 2026.Global supply chains are increasingly vulnerable to fraud, counterfeiting, and inefficient data management, leading to significant financial losses and operational disruptions. This paper presents a conceptual framework that leverages blockchain technology, radio‐frequency identification (RFID), and decentralized storage (IPFS) to enhance traceability,
