Retrial phenomenon naturally arises in various systems such as call centers, cellular
networks and random access protocols in local area networks. This paper gives a …

In this paper, we consider a two-user and a three-user slotted ALOHA network with multi-
packet reception (MPR) capabilities and a queue-aware transmission control. In this setting …

In this work we analyze a novel queueing system for modeling cooperative wireless
networks. We consider a network of three saturated source users, say a central and two …

A single server retrial queueing system with two-classes of orbiting customers, and general
class dependent service times is considered. If an arriving customer finds the server …

In this work, we investigate a slotted-time relay assisted cooperative random access wireless
network with multipacket (MPR) reception capabilities. MPR refers to the capability of a …

We establish stability criterion for a two-class retrial system with Poisson inputs, general
class-dependent service times and class-dependent constant retrial rates. We also …

In this work we consider a single-server system accepting N types of retrial customers, which
arrive according to independent Poisson streams. In case of blocking, type-i customer, i= 1 …

In this work, we investigate the stability conditions of a multiclass retrial system with coupled
orbit queues and service interruptions. We consider a single server system accepting N …

This paper treats strategic joining and pricing policies in an M/M/1 retrial queue with orbital
search which is motivated by the application in call centers, where the server will make …

We study a single-server retrial queueing model with N classes of customers following
independent Poisson inputs. A class-i customer, which meets server busy, joins a type-i …
