چکیده

Voice over Internet Protocol is a technology of transmitting voice on the Internet. Human voice is digitized, encoded, and transmitted on the Internet in the form of voice packets. These packets are received at the other end, decoded and converted back to analog signal. Loss and delay of voice packets result in the degradation of voice quality, since voice is a real-time application. Consecutive losses worsen the situation.

Characterization and Modeling of Packet Loss of a VoIP Communication

In this work, a characterization and modeling of packet loss of a Voice over Internet Protocol (VoIP) communication is developed. The distributions of the number of consecutive received and lost packets (namely gap and burst) are modeled from the transition probabilities of two-state and four-state model. Measurements show that both models describe adequately the burst distribution, but the dec...

Simulation and Modeling of Packet Loss on VoIP Traffic: A Power-Law Model

In this paper, through an extensive analysis it is shown that VoIP traffic jitter exhibits self-similar and heavy-tail characteristics. From this analysis, we observed that α-stable distribution particularly gives the best goodness of fit; this fact has implications on the design of de-jitter buffer size. On the other hand, we investigate the packet loss effects on the VoIP jitter, and present ...

Simulation and Modeling of Packet Loss on Self-Similar VoIP Traffic

This paper investigates the packet loss effects on the VoIP Jitter, and presents a methodology for simulating packet loss on VoIP Jitter traces with self-similar characteristics. Because of its simplicity and effectiveness, the two state Markov model or Gilbert model is used to generate packet loss patterns. We proposed a new model for self-similar VoIP traffic, this model are based on voice tr...
