Abstract: The three-way handshaking time affects delay of data packets and number of bandwidth requests in WiMAX Mesh network. A fixed handshaking parameter scheme can not satisfy different QoS demands. To solve these problems, we propose a QoSDx scheme to dynamically adjust handshake parameters according to the node itself, the numbers and priorities of two-hop neighbor nodes, and their parameters. Simulation results show that QoSDx improves the overall performance under different scale networks. The average of the throughputs of four kinds of services increases by 10%.

Key words: WiMAX Mesh network, QoS, three-way handshaking
