| Abstract(in English) | To enhance the end-to-end throughput of multi-hop wireless network using unlicensed spectrum, this paper proposes a distributed coordination function (DCF)-based medium access control (MAC) protocol that enables a wide area centralized radio resource management (RRM). In the proposed protocol, after the acquisition of transmission opportunity in a traditional DCF-manner, a source station attempts to forward a medium reservation advertisement (MRA) frame to a destination station. MRA forwarding enables multiple stations constituting a multi-hop network to reserve the radio resource for their exclusive use throughout multi-hop wide area. MRA forwarding is also utilized to gather channel state information (CSI) and traffic state information (TSI) of stations at the central controller that is adaptively selected among the stations. After the MRA forwarding, based on the CSI and TSI of each station, the central controller dynamically allocates the resource blocks to the appropriate stations through the opportunistic two-dimensional scheduling using OFDMA scheme. Assigned RB information is notified to stations by relaying transmission schedule advertisement (TSA) frame and the stations transmit their DATA frames on the allocated RBs. Numerical simulation confirms that the proposed protocol enhances the end-to-end throughput of multi-hop network operating at unlicensed band. |
