Abstract -- We show the close relation between
network coding and queuing networks with negative
and positive customers. We use this relation to ob-
tain bounds on the energy consumption in a wireless
information exchange setting using network coding.
I. Introduction
We consider the problem where two nodes in a wireless
network need to exchange information with the help of a
single relay node, as depicted in Figure 1. By making use
of the relay, node A needs to deliver all its data to node C
and vice versa. Node B, therefore, has a queue of pack-
ets that need to be delivered to C and another queue of
packets that need to be delivered to A. In a traditional
wireless network, node B divide its available resources
