Network quality of services and the limitation of network installation budget are important concerns in the widespread deployment of mobile WiMAX access networks. This paper presents a novel quality of service optimization model for WiMAX networks utilizing multi-hop relay stations with special considerations of network budget limitation. The proposed model aims to optimize the network quality of services in term of the user access data rate guarantee and the radio service coverage to serve potential user traffic demand in the target service area by determining optimal locations to install base stations and relay stations in the multi-hop manner. The numerical results and analysis show that the proposed model can improve the user access data rate and enhance the network service coverage compared with other existing techniques.
