Abstract:
This paper studies channel assignment in multi-hop wireless networks in which nodes are equipped with multiple radios, each of
which can be assigned to a channel. We argue for an approach that rst
assigns channels independently of tra c, to achieve basic connectivity
and support light loads such as control tra c, and then dynamically assigns channels to the remaining radios in response to tra c demand. The
objective is to balance the need for a stable baseline topology and the
desire to maximize throughput by dynamically adapting the topology to
current network conditions. We call this a tra c-aware (TA) approach, in
contrast to both tra c-independent (TI) and tra c-driven (TD) channel assignment and topology control schemes found in the literature.
We formulate the problem as a two-stage mixed integer linear program
(MILP), and nd that our approach supports good connectivity and data
rates comparable to those achieved with a TD channel assignment, while
achieving lower resource utilization than TI approaches. We also quantify the tradeos involved in the decision of what proportion of radios
to enable during the tra c-independent stage and what proportion to
enable dynamically in response to changing tra c demands
