Network Planning and Optimization for Multi-Hop Relay Placement in WiMAX Networks
Wireless access networks can provide high level of quality of services at low network installation budget if the networks are planned by using proper methods. In this paper, the authors developed efficient network planning methods for Wireless Interoperability for Microwave Access (WiMAX) networks in which the multiple hops of relay stations are deployed. An integer linear programming model was applied to the proposed problems for WiMAX networks. The key contribution of the proposed model is two-fold. First, it aims at maximizing the quality of services of the networks, including the physical data rate and the received signal strength. Second, it aims at minimizing the cost to install the networks.
