Abstract:
Wireless technologies, such as IEEE 802.11, provide for multiple
non-overlapping channels. However, wireless interfaces have
limited capability, allowing each host to use only a small
number of channels at any time.
The focus of this talk is on the use of multiple channels within
a single wireless network, despite limited interface capabilities.
Based on asymptotic capacity results for constrained and
unconstrained channel assignment models, we argue that
substantial performance benefit can be obtained
by suitably allocating the channel resources across the hosts.
The talk will also discuss insights on protocol design,
as well as issues in practical implementation of multi-channel
wireless networks.
