Abstract
Voice communication is an emerging technology and has great importance in our routine life. Perceptual, Voice over Internet Protocol quality is an important issue for VoIP Apps services because VoIP Apps require real-time support. Many network factors (packet loss, packet delay, and jitter) affect to VoIP quality, to achieve this objective we used an approach based on Fuzzy Logic. We configure Resource Reservation Protocol application to control Token Bucket Algorithm and the simulation experiments are carried out with Opnet. In addition, compare Token Bucket with and without Quality of Service for measure network factors. In this paper, building Fuzzy Token Bucket System consists of three variables (Bandwidth Rate, Buffer Size, and New Token) in order to improve Token Bucket Shaper output variable (New Token) by Fuzzy Stability model for Voice over IP quality maintaining.
Highlights
voice over internet protocol (VoIP), known as IP Telephony, is the real-time transmission of voice signals using the Internet Protocol (IP) over the public Internet or a private data network
First scenario VoIP with Quality of Service (QoS), second scenario VoIP without QoS, and third scenario compare the previous result with VoIP based fuzzy logic token bucket
We have succeeded in proving Fuzzy logic define the criteria on which depend for maintaining quality voice over internet protocol (VoIP)
Summary
VoIP (pronounced as voyp), known as IP Telephony, is the real-time transmission of voice signals using the Internet Protocol (IP) over the public Internet or a private data network. (RSVP) Resource reservation is a network protocol that enables IP-based applications to obtain particular (QoS) for data flows. It should be considered as a protocol that delivers QoS requests to the nodes along the data flow path by maintaining appropriate states in these nodes to provide the requested service as in [2], [15]; VoIP uses a combination of Real-Time Transport Protocol and User Datagram Protocol over IP. The authors used different ways to improve VoIP, we used RSVP protocol for Token Bucket with applying on Matlab for Fuzzy Logic by using Opnet program results for realtime, and this is what distinguishes our paper from the rest of the articles
