| Abstract | An integrated cellular/WLAN network integrates the complementary beneficial features of cell and WLAN. Integration of heterogeneous networks is not sufficient to provide good quality of service to the multiservice. The admission of voice, video connections and data sessions in cell or WLAN require intelligent call admission control. In this thesis work, an integrated cellular/WLAN network is implemented with the voice and video rearrangement schemes. Bandwidth is reserved for new and handoff calls in cell and handoff and rearranged calls in WLAN. This thesis work involves the analysis of performance measuresof the cell and WLAN in a cellular/WLAN network in case of different bandwidth reservation sets. The influence of the voice and video rearrangement schemes is observed. The probability distribution and tail distribution of average data rate in cell and WLAN in different traffic cases are analyzed. The network performance due data penetration in the network is observed and analyzed.Bandwidth reservations for the prioritized calls are found to be very beneficial when the system is overloaded. The blocking and dropping are not increased beyond certain value when the network is slightly overloaded due to the bandwidth reservations. The study of the influence of rearrangement schemes in a cellular/WLAN network verifies the necessity of this scheme in an integrated network for load balancing, maintaining quality of service in the networks and for the reduction of blocking and dropping in the networks. Large bandwidth demand can be sustained by a cellular/WLAN network with rearrangement schemes. The average data rate distribution observed in WLAN overload and underload traffic cases in a completely and partially overlapping cellular/WLAN network suggests that high average data rate per data session can be achieved in the double coverage area due to the presence of high capacity WLAN. In case of dominant data traffic in the overall network, the average data rate per data session highly increases. |
