A more general whitespace architecture: refactoring the master-client paradigm

While some whitespace devices will be self-sufficient (“masters”), others will rely on help from other devices in order to access the whitespaces (“slaves”). Currently, this help is provided by a single master device. In this paper, we argue that (1) this assistance need not be provided by a single device and (2) the assisting device need not be a whitespace device. Instead, we can think of the “slave” as being helped by a whitespace device support network, i.e. a variety of devices which each supply a piece of the whitespace access puzzle.
