Abstract:

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.
