In summary, SFH-FAP aims to find an optimal frequency assignment, i.e., assign at least k I frequencies f ∈ F to every STRX I such that the expected induced interference is minimal, all separation/blocking constraints are met and the totally induced expected co- and adjacent channel interference is minimal.
Each cluster uses a different resource manager and an independent algorithm determining the next SU to assign frequency using the saturation metric label and frequency assignment maximizing the network objective.
Proposed novel CR saturation metric is determined as a level of freedom in selecting the frequency for the SU, taking into consideration channel limitations due to local PUs transmissions and a level of interference from adjacent assigned SUs as a combination of hard and soft frequency assignment constraints.
When the frequency assignment and subsequent combining is done at a central point, the resulting combination is a frequency-division multiplexed signal, as is discussed in Multiplexing.
We propose an alternative frequency assignment scheme to reduce FWM crosstalk by allocating frequencies to a set of unevenly spaced channels determined by an optical spreading code.
Frequency assignment problem can be abstracted as a multicoloring problem on a weighted hexagonal graph, where the weights represent the number of calls to be assigned at vertices.
In this paper we investigate the application of parameter control schemes to address a well-known variant of the Frequency Assignment Problem (fap).
To attack the second problem, we first design an algorithm based on the earliest time first scheduling to determine the application's finish time if a voltage and frequency assignment is given; then, we develop a genetic algorithm to search the solution space for the voltage and frequency assignment that minimizes the overall system energy consumption and meets the application's deadline.

This assignment scheme provides several advantages over previously proposed frequency assignment schemes, these include, a reduced optical bandwidth requirements, ease of computing, unlimited channel counts and the complete avoidance of FWM intrachannel crosstalk.
The distributed frequency assignment problem can be abstracted as a multicoloring problem on a weighted hexagonal graph, where the weight vector represents the number of calls to be assigned at vertices.
