||Today, mobile networks are faced with congestion which results in regular slowness given the
variation in the actual speed of the network, that is to say the time required to transmit all of the
data from a point to another. In third and fourth generation mobile networks, actual throughput is
not directly measurable, it actually consists of three separate indicators, latency, jitter and loss rate.
Many studies have shown that these parameters have a particular influence on congestion
problems. In practice, the effective speed on the network is inversely proportional to the latency.
However, the bit rate is four times the latency. Next, jitter is the variation of latency over time,
impacting the flow by influencing latency. In this article, we have examined the analysis of traffic
congestion in third and fourth generation networks in order to make a comparative study of the
congestion rate for good decision-making.
