With the increasing popularity and rising demand for high-rate wireless Internet access, traditional wireless access networks such as cellular network and Wireless Local Area Network (WLAN) are facing some challenges. The Wireless Mesh Network (WMN) is emerging as a flexible and low-cost alternative to provide multi-hop communications, supporting applications such as last-mile Internet delivery. The WMN has also become a promising technology in the merging of wireless networks. Some key technologies for the WMN networking, including network configuration, power control, mobility management, access control, and routing protocols, are analyzed; the routing protocol design in WMN and mobile Ad hoc network are compared. An example of WMN testbed based on WLAN and second-layer switching technology is given.
