Locating ONU Serving Units in Fiber Wireless Access Network (FiWi) By Using AOA Optimization Algorithms

Abstract

Combining an optical network with a wireless access network is known as a fiber wireless access network (FiWi). Combining the advantages of wireless and optical domains, this hybrid multi-domain network meets the simultaneous needs of customers for high capacity and data transmission speed. FiWi is self-organizing and exhibits the characteristics of reliability, durability, flexibility, and cost-effectiveness. It is difficult to install an optical network unit (ONU) in these networks. ONU deployment in FiWi facilitates network design simplification and improves performance in terms of cost-effectiveness and throughput. In this thesis, we employed the arithmetic optimization method (AOA) to determine the optimal locations for ONUs in the FiWi network. The optimal location of ONUs has two objective functions: the highest coverage for users and the lowest overlap among ONUs. According to the simulation results of the proposed method, it has a better execution time and cost improvement than other compared algorithms.
