The wireless networks are experiencing higher delay, higher error rate, and lower bandwidth compared to wired networks. The customers not only need mobility but also quality. It is a great challenge for the service providers to offer Quality of Service (QoS). The QoS parameters are divided into two categories such as Qualitative QoS parameters (reliability, security, etc.) and Quantitative QoS parameters (bandwidth, delay, jitter, etc). The requirements of the above parameters will vary from one application to another application. In this paper, the authors would like to propose an efficient technique to store the QoS requirements of data transfer and to evaluate the performance of data transfer with respect to delay.
