Abstract
Wireless mesh networking is seen as a promising paradigm to offer
cost-effective networking, with diverse applications from disaster relief to
enabling an all-wireless office. However, designing high-throughput wireless
mesh networks is a challenge, due to their bandwidth constraints and shared
medium. This involves solving interrelated scheduling, routing and
interference problems. In this work, we exploit the fundamental properties of broadcast medium and path diversity in wireless meshes to implement multipath
routing between a source and destination pair. Our approach is to use network
coding as a technique to ease the scheduling problem, exploit diversity and
deal with unreliable transmissions. In this talk, I will describe our
multipath forwarding algorithms and discuss design issues. Analysis and
preliminary results from a prototype testbed implementation show benefits of
our approach over existing approaches.
