Dynamic spectrum management in Legacy Military Communication Systems

Increasing demands are being placed on dynamic spectrum access as a result of overload of the frequency spectrum. In this paper we present a concept of frequency broker as a crucial element of coordinated spectrum management system for battlefield communication network. Critical problem in such system is automation of the collision-free frequency planning and management. In this paper, the solution of this problem basing on the graph theory is described. The new model of electromagnetic waves attenuation prediction is also presented.
