A High Throughput AP Selection Scheme for IEEE 802.11 Wireless Mesh Networks
一种高吞吐量的IEEE 802．11Mesh网AP选择算法

Current AP selection schemes for IEEE 802.11 wireless mesh networks(WMNs)are only based on the measurement of the links near the mesh client,which fail to offer the client a high capacity Internet access.In this pa- per,an EXT(Expected Transmission Throughput)based AP selection scheme for WMNs is proposed.EXT scheme considers both the transfer capacities of the mesh routers near the client and the connecting time of the links between the client and the routers,with the purpose of achieving maximum throughput.Furthermore,we give a practical im- plementation of EXT according to the characteristics of WMNs and the motion of the client.Simulation is conducted with NS-2,which shows the proposed scheme has a remarkable improvement over the existing RSSI based scheme
