The emerging WiMAX technology (IEEE 802.16) is a fourth generation standard for low-cost, high-speed and long-range wireless communications for a large variety of civilian and military applications. IEEE 802.16j has introduced the concept of mesh network model and a special type of node called Relay Station (RS) for traffic relay for Subscriber Stations (SSs). A WiMAX mesh network is able to provide larger wireless coverage, higher network capacity and Non-Line-Of-Sight (NLOS) communications. This paper studies a Multi-hop FAir Scheduling for Throughput Optimization (MFASTO) problem in WiMAX mesh networks.
