Mobility performance analysis in wireless network based on a cross-layer network calculus model

Abstract

Inspired by the idea of cross-layer analysis and Network Calculus theory, an analytical model for wireless network, which combines the essential knowledge of both, is proposed in this paper by mapping the characteristic of network layer, link layer and physical layer into concatenation of a sequence of Network Calculus components. In addition, the effect of terminal mobility has been considered in our modeling. The proposed model is applied to derive the service curve of wireless network, which consequently enables the calculation of delay and backlog performances under different terminal moving speeds. Simulation results verify the fact that our model provides an accurate performance analysis of wireless network concerning the impact of terminal mobility.
