Location robustness in database-driven white spaces network

The recent FCC ruling has enforced database-driven white spaces network (WSN) in which the database relies on a secondary user (SU) to determine his location to query the database for available spectrum. However, this creates a critical loophole for mounting GPS spoofing attack, which can potentially result in primary user (PU) interference. The adversary attacks SUs´ GPS which results in SUs querying the database with false location and obtaining incorrect available spectrum information. In this paper, we examine the impact of a GPS spoofing attack on database-driven WSN, propose a spoofing attack detection mechanism and provide simulation results of the scheme. We also propose an analytical model for the detection mechanism and derive an upper bound for the convergence time of our model. To the best of our knowledge, this is the first paper to examine the impact of a GPS spoofing attack on database-driven WSN and present a detection mechanism for the same.
