Abstract

In this paper, a methodology for evaluations of quality of service (QoS) in wireless networks based on network calculus (NC) models is introduced. The proposed model employs modular concatenation of selected NC components to represent the effect of wireless links on the QoS performance at the link-layer. We present a mathematical analysis that applies the model to evaluate the performance of a wireless video streaming application, by deriving estimates of the playback delay and buffer size at the receiver side. Owing to the analytical strength of NC, the model offers an efficient way of deriving end-to-end QoS characteristics in wireless networks.
