Title
Adaptive Quality of Service in Voice over IP Communications
Abstract
The present work proposes an adaptive solution to provide quality of service in Voice over IP communications. This solution is based on three components that interact inorder to achieve higher quality in voice communication. The first two consist in changing the Codec and the transport protocol in real-time during a conversation; the third consists in using a Forward Error Correction mechanism to recover from loss packets. To demonstrate the voice quality obtained by this solution, a VoIP client application was developed, compatible with other VoIP clients, to implement the proposed quality of service algorithm and control the voice quality during a conversation. The results of the experimental measurements and simulations performed demonstrate that this solution is viable and significantly increases the voice quality of VoIP communication.
