As technology advances in society the need for networks has become essential. In network study the authors found many advantage as well as disadvantage related to wired and wireless scenario. So, while considering design issue of network QoS i.e. Quality of Service is the main consideration of network. In wireless networks QoS deals with many systems sensitive parameters they are average delay, end to end delay, throughput, packet loss, energy consumption, latency, etc. Due to nondeterministic behavior of the wireless channel and queuing mechanisms of nodes also the probabilistic that means where there is multiple possibility of outcomes each with different certainty analysis of QoS is essential.
