Dynamic spectrum access can enable secondary network users to access unused spectrum, or whitespace, which is found between the transmissions of primary users in a wireless network. The main design objectives for secondary user access strategy are to be able to "Scavenge" spatio-temporally fragmented whitespace opportunities while limiting the amount of interference caused to the primary users. In this paper, the authors propose a novel secondary user access strategy which is based on measurement and modeling of the whitespace as perceived by the secondary network users.
