Multimedia Issue in Wired Network

The provision of Quality of Service (QoS) in wired network is a challenging task. The provision of QoS in wired network is necessary to support the multimedia applications. QoS represents the grade of service assured by the network to an application. QoS parameters in wired network include delay, bandwidth, and reliability. Depending on the actual QoS requirements of an application, the issues involved in guaranteeing QoS are different.

Solution in NS2

  • Multimedia traffic in ns2 can be used by patching the required .cc and .h files in existing ns2 package followed by rebuilding.

  • The YUV Video sequence is compressed and sender trace file is generated for the compressed video sequence. Data is read from trace file and sent to the receiver using patched new udp agent. Video is reconstructed from the received trace file.

  • Multimedia traffic can be tested under wired network. Performance can be evaluated in terms of Peak Signal to Noise Ratio (PSNR).
