In this paper, the authors investigate the transmission of data between client and server through different IEEE 802.11 wireless LAN multi-HOP network. To improve this issue, the Transmission OPportunity (TXOP) mechanism is defined in the IEEE 802.11e standard, with which a wireless node can transmit multiple frames consecutively for a maximum channel occupancy time, called TXOP limit. This paper considers the performance of the TXOP mechanism for multi-hop wireless networks. Focusing on a three-node chain topology, they model it as a tandem queuing network with two nodes.
