E2E QoS Support Aided ITPC WiFi Network for Baghdad City: Performance Analysis

The ministry of communications (MoC) in Iraq owns the Iraqi Telecommunication and Post Company (ITPC). MoC mainly oversees the construction and operation of ITPC which provides “Wireless Internet service” in Iraq. ITPC is the main state owned company that involves in providing internet service to the public. ITPC has regarded that last mile connectivity by wireless broadband access as a cost-effective solution. In this context, WiMAX has been chosen to support the required Quality of Service (QoS) to the end users. ITPC also has chosen WiFi for last mile access. In this paper, we propose a design for ITPC WiFi network for Baghdad city based on location reality to offer internet service. We have modeled and simulated the ITCP WiFi network using OPNET 14.5 simulator. Specifically, two scenarios of ITPC WiFi network have been designed, devised and taken up for analysis. The scenarios are as follows: (1) Designing ITPC WiFi network deprived of end to end QoS arrangement and (2) with end to end QoS arrangement to enhance the performance. Both the scenarios are investigated using various types of traffic and comparisons have been performed. Our studies have shown that better performance can be obtained when ITPC WiFi network exploit E2E QoS solution. Also, it is demonstrated that delay endured by the network gets reduced by 48% and the throughput increases by 8%.
