Multi-hop wireless networks are increasingly becoming popular and
finding application in diverse scenarios such as mesh networks and
sensor networks. The broadcast nature of the wireless medium gives
rise to interference, which limits performance. To alleviate this, it
is becoming common to harness the availability of multiple frequency
channels in these networks. However, many routing and scheduling
challenges arise when the network comprises devices with heterogeneous
channel-switching capabilities. Heterogeneity in channel
characteristics further adds to these challenges.
In this talk, I will discuss the implications of such heterogeneity in
multi-channel wireless networks, and present some theoretical results
on asymptotic capacity scaling, as well as scheduling in networks of
realistic scale. I will conclude by briefly discussing some of my
ongoing work on designing protocols for such networks.
