ALOHA random access protocols are distributed protocols based on transmission
probabilities, that is, each node decides upon packet transmissions according to a …

For slotted random access systems, the slotted ALOHA protocol provides the maximum
throughput of 0.368 (packets/slot) while in the category of splitting (or tree) algorithms, the …

This work presents an innovative, adaptive and optimal approach for Slotted-ALOHA
protocols in Satellite Networks. Most ALOHA random access protocols are based on the …

In this paper, we study the behaviour of the slotted Aloha multiple access scheme with a
finite number of users under different traffic loads and optimize the retransmission probability …

Simple retransmission strategies are adopted to allow for the utilization of the ALOHA
synchronous random access protocol. Numerical simulations were performed using a model …

We consider rate control for random access networks. In earlier work, we proposed a rate
control mechanism which we analyzed using the well-known slotted Aloha model with an …

This concise paper explores some of the boundaries in performance of slotted ALOHA
systems by analyzing a simple and almost optimal centrally supervised control. Our control …

A class of slotted ALOHA dynamic control strategies is considered. These strategies are
simple to implement and can yield lossless and stable operation for arbitrarily large user …

This paper examines the stability of the randomized slotted ALOHA (RSA) protocol. A
Markov chain for a finite number of single buffer users is derived and this is complemented …

Random access plays important role in modern communication systems not only for
establishing connections in cellular systems but also for direct packet transmission in …
