On the Feasibility of the Link Abstraction in (Rural) Mesh Networks
TLDR
We present detailed measurements to show that the PHY layer in these settings is indeed stable and predictable, due to multipath delay spread. Expand

Loss-aware network coding for unicast wireless sessions: design, implementation, and performance evaluation
TLDR
We show that the design space for effective redundancy in local network coding is quite large, which makes optimal formulations of the problem hard to realize in practice. Expand

Can they hear me now?: a case for a client-assisted approach to monitoring wide-area wireless networks
TLDR
We present WiScape, a framework for measuring and understanding the behavior of wide-area wireless networks, e.g., city-wide or nation-wide cellular data networks using active participation from clients. Expand

Demultiplexing activities of daily living in IoT enabled smarthomes
TLDR
We propose a data driven three-step de-multiplexing approach that simplifies the ADL recognition problem by first segmenting the event stream into periods of interest, before feeding to a classifier. Expand
