Abstract(in English) In this papaer, We proposed QoS aware and Fainess aware MAC protocol in multihop network. In the proposed method, Minimum Contention Windowvalue (CW_) is adaptively controlled based on the size of the buffered data in the node, and others in the node's transmission range increase CW based on that. When the medium is highly loaded, because of number of nodes with high buffer usage ratio increase, CW is fast increaced. Because the low priority AC (access category) has the largest CWmax value while the highest priority AC has small CWmax value, QoS can be guaranteed. The performance of the proposed method is evaluated by computer simulation. Studies show that, with the proposed method, QoS can be guaranteed and buffer overflow decrease compared to conventional methods. Moreover, the proposed method improves throughput performance.
