Abstract:
Dynamic spectrum access (DSA) holds the promise
for more efficient utilization of the spectrum, while requiring
greater cooperation between PHY, MAC, and NET layers to allocate
resources and dynamically react to changing network conditions.
In this paper, we propose Channel Assignment based on Routing
Decisions (CARD), a mechanism that combines channel assignment
and topology control so that at any given time the cognitive network
self-organizes into the topology that is best suited to support the
current offered traffic. CARD is a distributed mechanism, and each
network node relies on local information only. We show that CARD
results in an improvement in route length (and, thus, end-to-end
delay), aggregate network capacity, and, in some situations, energy
efficiency.
