Multi-Channel Wireless Networks: Theory to Practice

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.
