| Abstract | Spectrum management is the process of deciding how radio frequency (RF) spectrum may be used in a geographical region and who may use it. Traditionally, spectrum management has been executed as an administrative and political process with the intent of making lasting decisions. Its lack of responsiveness and resolution causes much spectrum to lay fallow since most users rarely need spectrum continuously and ubiquitously. In this paper, we propose an alternative spectrum management approach that enables management at a greater temporal and spatial resolution using networks and wireless ad hoc and mesh networking technologies. Three different spectrum management ideas are described. The Synchronous Collision Resolution (SCR) MAC protocol enables a strict arbitration of spectrum access based on spectrum rights thus enabling a hierarchy of networks in the same spectrum that always guarantees the primary rights holder precedence. Second, it autonomously manages the use of an arbitrary number of channels in the same network. The third and most exciting idea is a new fast command and control model for spectrum management. An underlying ad hoc network built using the Nodes State Routing* (NSR) protocol is used to track and manage the use of spectrum of attached RF emitters. NSR tracks the state of the network by collecting and disseminating the states of the nodes. These states can include relevant information on the spectrum these nodes are using and are observing others use. Thus the network supports tracking and monitoring spectrum use spatially in near real time. Spectrum management utilities built on top of the network could allow users and spectrum managers to rapidly negotiate the use of spectrum and assist spectrum managers in identifying unused spectrum and emitters causing harmful interference. We conclude with proposed standardization and regulatory changes to make this feasible. |
