Determination of QoS metrics in wireless sensor networks by using queuing theory

Traffic classes in multimedia WSNs are required high bandwidth and reliable transfer through the network because of large amount of data size. However, some applications of WSNs are required high quality. In this scenario, main purpose in designing of the sensor networks and nodes becomes how to conserve energy and prolong network life. In order to increase quality of services (QoS), a measurement of probability of blocking of the arrival packets were suggested by using queuing theory. Probability of blocking gives us clear picture how system specification should be chosen so that blocking state would be minimized.
