WSNs require specific application designed for current phenomenon and based on some curtain quality of services (QoS) metrics. Unlike wired and mobile wireless networks, WSNs need totally different QoS measurement because of the resource limitation and low computational speed. In multimedia WSNs transferring of big-size video data is important factor for QoS metrics. Therefore effective buffer management systems are required in order to increase data transmission quality. In the paper, two types of multimedia classes-video and picture were analyzed and relative QoS model were proposed. The main measurement of the QoS metric is to decrease the probability of blocking of arrival packets. Furthermore, exact formula for the main indicator of the QoS measurement - Probability of Blocking is suggested. This model gives us clear understanding on selection of relevant specification of the microcontrollers and transceivers.
