Abstract

Wireless access technologies have been maturing and becoming the natural selections to establish infrastructures of wireless mesh networks (WMNs). IEEE 802.11 wireless local area networks (WLANs) have recently been the popular choices to carry out experiments on wireless mesh networks. Numerous research directions are being investigated regarding, for example, signal interference, MAC protocol designs, channel assignments, path routing and metric selections, and transport layer performance analysis, etc. In this paper, we examine the relationship among topologies of wireless mesh networks, channel assignment issues, and number of radio tranceivers in the meshing stations. Path establishment protocol between source and destination stations for multi-radio multi-channel wireless mesh networks is implemented for experiments. Different frequency channels are used for a multi-hop path setup operation. Setup durations for multi-hop connections are measured and reported in the paper.
