Abstract

This paper presents a novel network design and optimization model for mobile WiMAX access networks utilizing multi-hop relays. The proposed model aims to determine optimal locations of base stations and relay stations so that the network can guarantee quality of services in term of the access data rate and the service coverage to serve potential user traffic demand in the target service area. Numerical network design results demonstrate that the proposed model can improve the user access data rate up to 60% and enhance the network service coverage up to 12% compared with the other existing models in literature.
