%X In order to study the effect of terminal moving on QoS in wireless networks, a cross-layer network calculus model is established to calculate the delay and backlog performance parameters when communication terminals are under different moving speeds. This model combines the idea of cross-layer analysis and network calculus theory, which mapping the different characteristic of network layer, link layer and physical layer into a series of network calculus components. Based on the cross-layer network calculus model, the corresponding service curve can be derived conveniently when moving terminals are under different moving speeds using network calculus theory, in addition, the backlog and delay performance parameters can be calculated. Simulation results veried that the established cross-layer network calculus model can analysis the backlog and delay performance in wireless networks under different terminal moving speeds.
