Abstract-- Efficient spectrum allocation in dynamic spectrum
systems is a challenging problem, particularly for multi-hops
transmissions. The inter-dependence between route selection and
spectrum management makes it important to examine interaction
between the two and the corresponding performance and com-
plexity tradeoffs. In this paper, we explore two design method-
ologies: a decoupled design where these tasks are carried out
independently by different protocol layers, and a collaborative
design that integrates them into a single task. Experimental
results show that the collaborative design, if well-provisioned,
