Qos Analysis Of Data Communication Using NS 2

Performance of recent multimedia transmission over wireless communication systems without affecting its QoS, is a major challenge in recent mobile node communication. Cognitive radio network fulfils this requisite. Spectrum inefficiency problems due to limited spectrum resource allocation are overcome by optimization of spectrum utilization with suitable algorithms. In this paper, the importance of multimedia transmission with required QoS for the secondary users has been justified. The QoS parameters are analysed for the mobile nodes over a wireless network with suitable routing algorithm is considered. The discussions includes providing an efficient QoS support for multimedia transmission with handoff strategies and efficient computation of the performance parameters with suitable simulator. The NS2 approach and its importance in determining the network parameters are also discussed in detail.
