Architecture and algorithms for an
IEEE 802.11-based multi-channel
wireless mesh network

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.
