Cross-Layer Performance Evaluation of IP-Based Applications Running over the Air Interface

We propose a novel cross-layer analytic approach to performance evaluation of delay/loss sensitive IP-based applications running over the wireless channels. We firstly extend the small-scale propagation model representing the received signal strength to IP layer using the cross-layer mapping. Then, we replace the resulting IP layer wireless channel model by an artificial equivalent arrival process using the error/arrival mapping. To get performance parameters of interest we use this process together with arrival process modeling the traffic source as an input to the queuing system with deterministic service time, limited number of waiting position and non-preemptive priority discipline representing the IP packet service process of the wireless channel.
