Architecture and algorithms for an IEEE 802.11-based multi-channel wireless mesh network 指導教授:許子衡 老師 學生:王志嘉 Introduction (i) The advertised 54 Mbps bandwidth for IEEE 802.11a/g wireless LAN interface is the peak linklayer data rate. The bandwidth problem is further aggravated for multi-hop ad hoc networks due to interference from adjacent hops on the same path as well as from neighboring paths. Introduction (ii) Bandwidth aggregation is routinely used in 802.11 -based wireless LANs that operate in infrastructure mode, where traffic to and from wireless nodes is distributed among multiple interfaces of an access point or among multiple access points.
