                                ABSTRACT

In this work, we study congestion control for unicast sessions over
wireless networks with intersession network coding. The key intuition
is that flows that are coded together do not compete for resources,
and congestion control mechanisms need to be modified to take this
into account. We take the following steps. First, we formulate the
problem as utility maximization and present a distributed solution.
Then, using the structure of the optimal solution, we propose minimal
changes to current transport and queue management protocols so as to
make them "network coding-aware," in the sense that they make
decisions based on the network coding and congestion state. Finally,
we demonstrate, via simulation, that our schemes outperform network
coding-unaware protocols, such as standard TCP, and achieve
near-optimal performance.
