A Simple Yet Effective Scheme for the Maintenance of Proxy Information in IEEE 802.11s Wireless Mesh Networks

Executive Summary

According to the IEEE 802.11s draft standard, the mesh STA may maintain proxy information on STAs that are associated with a collocated access point or are behind a collocated portal. The proxy information plays a very important role in wireless mesh networks for additional delays may be introduced owing to the absence of proxy information during frame forwarding. While the method for maintaining proxy information is beyond the scope of the standard, two basic mechanisms had been integrated in the early drafts of IEEE 802.11s - the proxy registration procedure and the associated station discovery protocol.
