Frequency Fitness Assignment

Real-valued Frequency Assignment

We consider the binary constraints formulation of the frequency assignment problem in its most general form: for an arbitrary metric space, with frequencies taking arbitrary real values, and with possibly innnitely many constraints. We obtain some necessary and suucient conditions for the problem to have a solution with a nite span. When the metric space is the set of integers, we give an exact...

Frequency Assignment Problems

The ever growing number of wireless communications systems deployed around the globe have made the optimal assignment of a limited radio frequency spectrum a problem of primary importance. At issue are planning models for permanent spectrum allocation, licensing, regulation, and network design. Further at issue are on-line algorithms for dynamically assigning frequencies to users within an esta...

Frequency Assignment – Models and Algorithms

Wireless connections are established by the use of a transmitter which is sending radio waves at a specific frequencies to a receiver. Nowadays, due to the variety of different services, only a restricted part of the radio spectrum is available. The set of available frequencies for a provider of a wireless communication service is limited even further by concurrent providers and local frequency...

The dynamic frequency assignment problem

In this paper, we consider a frequency assignment problem occurring in a military context. The main originality of the problem pertains to its dynamic dimension: new communications requiring frequency assignments need to be established throughout a deployment. The problem decomposes in three phases: assignment of an initial kernel of communications, dynamic assignment of new communication links...
