Network Calculus Modeling and QoS Analysis for Wireless Packet Networks

A modeling method for wireless packet networks based on network calculus (NC) theory, employing the concatenation of NC components to represent the effects of the modules constituting wireless packet networks model, is proposed in this paper. Three well-known scheduling algorithms are modified to agree with the proposed NC model. A new scheduling algorithm for packet networks is proposed in the context of NC. Simulations then are done to study the end-to-end QoS characteristics of the networks with different scheduling algorithms. The result shows that, in terms of the criterions defined in NC model, the scheduling algorithm proposed in this paper outperforms the existing three algorithms.
