摘要

本文的目的是提出一种利用改进的动态映射算法和多路径传输(MPT)和多描述编码(MDC)来提高多媒体应用服务质量的新技术。通过在应用层采用MDC，在传输层采用UDPLite，在网络层采用多路径，在MAC层采用改进的动态映射，实现了性能的提高。与传统方法相比，该方法的峰值信噪比(PSNR)提高了30.84%，延迟降低了18.57%。本文的目的是提出一种利用改进的动态映射算法和多路径传输(MPT)和多描述编码(MDC)来提高多媒体应用服务质量的新技术。通过在应用层采用MDC，在传输层采用UDPLite，在网络层采用多路径，在MAC层采用改进的动态映射，实现了性能的提高。与传统方法相比，该方法的峰值信噪比(PSNR)提高了30.84%，延迟降低了18.57%。

An Integrated Cross Layer Design to Enhance the Quality of Service of Video Streaming in Mobile Adhoc Networks

The intent of this paper is to put forth a novel technique for improvising the QoS of multimedia applications in by using Modified dynamic mapping algorithm and Multipath transport(MPT) and Multi Description Coding(MDC). The improvement is attained by applying the MDC at application layer along with UDPLite in transport layer and multipath at network layer and Modified dynamic mapping in MAC Layer.Thismethod attains an increase of 30.84% in Peak Signal to Noise Ratio (PSNR) and 18.57% decrease in delay in contrast to the conventional methods.
