    3232Our WiMAX research involves analyzing the cross-layer affects of the system parameters used for the Bandwidth Contention Process. We are specifically looking at how these parameters affect a subscriber station's (SS) throughput, packet loss rates, and vulnerability to Distributed Denial of Service (DDoS) attacks. Software simulations using the NS-2 simulator manipulated three system parameters for a set of SS that included client and attacker SS's. The parameters, request retires, backoff start, and frame duration, were set to a low, medium, and high value within their respective range. All attacker SS's parameters were set to the same value and all client SS's parameters were set to same value, but the attacker and clients stations could differ. Seven replications of each combination of parameter settings were conducted and ANOVA analysis indicates that frame duration and request retries plays a significant role in SS's throughput.
