“…Authors in [6] has proposed Insensitive Call Admission Control for Wireless Multiservice Networks, in which multiservice wireless system enforcing the CAC scheme is reversible and its stationary distribution is insensitive to the channel holding time distribution has been proposed. Woojin Seok et al [7] has proposed Two-Tier Call Admission Control to Minimize CBP/CDP in Heterogeneous Wireless Networks, but in that scheme they did not avoid unnecessary hand off occurs due to high velocity user. Qian Huang et al [1] derived Loss Performance Model for Hierarchical Heterogeneous Wireless Networks With SpeedSensitive Call Admission Control, in which they derived approximate traffic loss model for two-tier hierarchical CAC but they did not consider any particular practical networks and its architecture, they proposed only numerical model.…”

This paper proposes and analyzes dynamic speed sensitive call admission control (DSSCAC) for WiMAX-WLAN integrated overlay networks. A hierarchical overlay structure is an alternative solution that integrates existing and future heterogeneous wireless networks to provide subscribers with better mobile broadband services. This proposed DSSCAC avoids unnecessary handoff and reduces signaling overheads, increases utility of the network by dynamically varying bandwidth reservation for handoff calls. Proposed DSSCAC is analyzed for two different coupling architecture of integrated WiMAX-WLAN overlay network.Performance of such integrated network is necessary for network planning and dimensioning.
