WiMAX with wired infrastructure has been popularly deployed. However, due to the high cost of the construction and the maintenance of the infrastructure, researchers have focused their investigations on IEEE 802.16 wireless multi-hop networks with low cost and high scalability. With IEEE802.11e WLANs, which provide user-level QoS support for WLANs, the multi-hop networks of IEEE 802.16 using DiffServ...
A relay station (RS) in IEEE 802.16j mobile multi-hop relay (MMR) networks provides access links to far-off subscriber stations (SSs) and hidden subscriber stations. The RS also relays data from a base station and other RSs while maintaining backward compatibility with legacy subscriber stations in existing IEEE 802.16 networks. Much research is being performed to finalize the standard; however, how...
