Method for Providing Efficient Real-Time Multimedia Communication using VoIP Over Communication Channels
The Voice packets and the Video packet are transmitted in the existing infrastructure using the Voice Over Internet Protocol (VoIP). VoIP (Voice over IP, VoIP and IP telephony) has become more popular in the recent years due to its advantage of low-priced calls than to the existing Public Switch Telephone Network. The significant objective of this research work is to improve the performance of multimedia service in the wireless telecommunication through the mobile VoIP. This paper explains the modulation scheme based approach for improving the performance of voice over the IP telephony. The proposed modulation selection method selects the modulation for the real time multimedia traffic based on the channel condition. The algorithm in the proposed system reduces the modulation switching time and increases the throughput. The performance metrics taken to ensure the quality are throughput and Mean Opinion Score.
