System for Distributed Spectrum Sensing In a Highly Mobile Vehicular Environment

摘要

A system and method for detecting spectrum holes in a region is disclosed. The system comprises a requesting module, a detecting module and an aggregation module. The requesting module retrieves channel availability data for a region. The channel availability data describes potential availability of a channel. The detecting module obtains a set of values for the channel by spectrum sensing at a set of locations in the region based at least in part on the potential availability of the channel. The aggregation module aggregates the set of values for the channel over the set of locations in the region to obtain a first value for the channel and determines the availability of the channel based at least in part on the first value for the channel.
