Abstract-- Efficient spectrum allocation in Open Spectrum
systems is a challenging problem, particularly for devices with
constrained communication resources such as sensor and mobile
ad hoc networks. We propose a device-centric spectrum manage-
ment scheme with low communication costs, where users observe
local interference patterns and act independently according to
preset spectrum rules. We propose five rules that tradeoff per-
formance with implementation complexity and communication
costs, and derive a lower bound on each user's allocation based
on these rules. Experimental results show that our proposed
rule-based approach reduces communication costs from efficient
