| Abstract: | Backbone performance is one of the main bottlenecks in multi-hop wireless Mesh network.In this paper, Wireless Mesh network testbeds are constructed on the IXP425 and x86 platform individually with the Linux open source code. Within these testbeds, serials of experiments are carried out to analysis the wireless Mesh network performance with signal-link and dual-link based IEEE802.11a standard. Experiment results show that CPU packet forwarding ability is one of the main factors which influence the performance of multi-hop wireless Mesh network. On the x86 platform, with a 2.6G CPU, the backbone bandwidth can reach 110Mbps based on dual-link and the multi-hop wireless Mesh network performance is promoted effectively. |
