A token-based scheduling scheme for WLANs supporting voice/data traffic and its performance analysis
Most of the existing medium access control (MAC) protocols for wireless local area networks (WLANs) provide prioritized access by adjusting the contention window sizes or interfram...

Heavy traffic analysis of polling models by mean value analysis
In this paper we present a new approach to derive heavy-traffic asymptotics for polling models. We consider the classical cyclic polling model with exhaustive or gated service at ...

Reduction of a polling network to a single node
We consider a discrete-time tree network of polling servers where all packets are routed to the same node (called node 0), from which they leave the network. All packets have unit...

Retransmission Strategies for Cyclic Polling over Wireless Channels in the Presence of Interference
In this paper we consider retransmission strategies for centralized cyclic polling-based systems over wireless channels subject to external interference. The considered strategies...

A note on polling models with renewal arrivals and nonzero switch-over times
We consider polling systems with general service times and switch-over times, gated service at all queues and with general renewal arrival processes. We derive closed-form express...
