Abstract

The objective of this paper is to propose a novel method for enhancing the QoS of multimedia applications in mobile adhoc networks by using Multipath and Multi Description Coding. The enhancement is achieved by implementing the Multi Description Coding (MDC) at application layer along with Connectionless Light Weight Protocol (UDPLite) in transport layer and multipath at network layer. This approach achieves an increase of 12.75% in Peak Signal to Noise Ratio (PSNR) which is an improvement in PSNR as compared to the conventional methods.
