Abstract:
With the advent of cognitive radio technology,
new paradigms for spectrum access can achieve near-optimal
spectrum utilization by letting users sense and utilize available
spectrum opportunistically. Recently, graph-coloring models have
been used to produce fair, efficient and optimal spectrum
allocations for a given network topology. However, topology
changes (e.g., due to user mobility) can incur significant signaling
traffic to reallocate spectrum, consuming valuable resources. We
propose a frequency-spread multiple access (FSMA) scheme that
is topology-transparent, and numerical results suggest that it is
suited for opportunistic spectrum access in a sparsely-connected,
low-density mobile ad-hoc network.
