English Abstract

In the last decade WiMAX (Worldwide Interoperability for Microwave Access) was appeared in Erbil.

For maximizing the company profits, operators have to improve the quality of their networks, this can be done through setting a well-studied plan for their network infrastructures in terms of cost.

Researchers proposed various models to solve the planning problem, but most of them ignored some performance measures that this paper used to evaluate the proposed method with the existing approach , those performance measures are upload consideration, some Key Performance Indicators such as throughput estimation, the total number of connected/rejected users (%) within all tried others and Block Error Rate (BLER).

Previous method to solve network planning was manual method, but due to problematic complication and dealing with many factors, it is impossible to find optimal network configuration using a manual method.

Thus, in this paper automated wireless network planning and optimization is used to solve the problem by sequential approach that divides the entire problems to sub-problems.

This paper addresses the planning, evaluation, analysis, optimization, and multi-objective system performance of a network on the mobile WiMAX standard, namely (IEEE 802.16e) in the city of Erbil.

A new model for planning problem of such network was proposed, the objectives of the proposed model are not only to identify optimal amount, but also the optimum location of Base Stations (BSs) in targeted areas.

In addition, the proposed model decomposes the entire problem into three different phases dimensioning, frequency allocation and optimization.

The feasibility of the final network designs evaluated by the FORSK-ATOLL simulator.

Moreover, multi-objective network planning results demonstrate that the proposed model can reach high system performance with cost-effective network infrastructure.

This has been achieved by comparing the proposed model with the existing model of Newroz Tel Company in the city of Erbil, which resulted in reducing cost by 20% of total cost.
