We have studied a Geo/G/1 retrial model with state-dependent and voluntary services in
discrete-time frame. The concept of Bernoulli vacation is also considered wherein, after the …

This study analyzes the performance of a queue length-dependent overload control policy
using a leaky bucket (LB) scheme. This queueing model is applied to the operation of a …

Due to the widespread applicability of discrete-time queues in wireless networks or
telecommunication systems, this paper analyzes an infinite-buffer batch-service queue with …

Discrete-time queueing systems have widespread applications in packet switching
networks, internet protocol, Broadband Integrated Services Digital Network (B-ISDN), circuit …

This paper investigates an infinite-buffer single server queueing system wherein customers
arrive according to a discrete-time renewal process and are served in batches of random …

Any event that results in sudden change of the normal functioning of a system may be
thought of as a catastrophe. Stochastic processes involving catastrophes have very rich …

Discrete-time queueing models find a large number of applications as they are used in
modeling queueing systems arising in digital platforms like telecommunication systems and …

Discrete-time queues have increasingly diverse spectrum of applications in the modern
packet-basedcommunication systems. Due to the wide range of applicability of such queues …

We analyze customer losses in busy-periods of preemptive and non-preemptive oscillating
MX/G/1/(n, a, b) systems. Specifically, we propose a recursive scheme to compute the …

We propose a novel overload control method with hysteresis property; that is, we analyze
the M/G/1/K queueing system where the service and arrival rates are varied depending on …
