protocol theory
In CSMA P-persistent (“probabilistic-persistent”) a devices samples the line, and if idle transmits. If busy, samples it until it’s idle and then transmits but only with a given probability. The purpose of this is to reduce the conflicts of multiple devices wanting to

[PDF] On the Capacity of p-Persistent CSMA
The CSMA-based algorithms constitute a heart of contemporary wireless media access control technology. In last decades, various enhancements have been introduced to basic CSMA schemes, first of all, in order to support collision avoidance. At the same time, the performance analysis of the p-persistent CSMA has gained a renewed interest recently since the behavior of many CSMA protocol…

High-Performance Long Range-Based Medium Access …

p-persistent CSMA protocol are much closer to being optimal, the load is spread more uniformly over the channels at high traffic. Thus, we see a drop in collision rate and increased throughput by using the adaptive p. For this reason, the average throughputs of

1-persistent CSMA To avoid idle channel time, 1-persistent protocol used Station wishing to transmit listens to the medium: 1. If medium idle, transmit immediately; 2. If medium busy, continuously listen until medium becomes idle; then transmit immediately with probability 1 Performance 1-persistent stations are selfish If two or more stations becomes ready at the same time, collision guaranteed

Q-Learning and p-persistent CSMA based rendezvous …

In this paper, we propose a novel rendezvous protocol, known as QLP, which is based on Q-learning and the p-persistent CSMA protocol. With the QLP protocol, CR nodes learn which channels are best for rendezvous and thus adapt their behavior to visit those channels more frequently.
