Problem Formulation

Different optimization functions are possible:

1.

Total throughput maximization

2.

¢-proportionally-fair throughput maximization

Dynamic Spectrum Allocation Problem:

Given dynamic demands Dij(t,¢t), assign non-interfering time-spectrum blocks to nodes, such that the demands are satisfied as much as possible.

Captures MAC-layer and

spectrum allocation!

Can be separated in:

Time

Frequency

Space

Throughput Tij(t,¢t) of a link in [t,t+¢t] is

minimum of demand Dij(t,¢ t) and capacity C(B) of allocated time-spectrum block

Min max fair

over any time-window ¢

Interference Model:

Problem can be studied in any interference model!
