Level-based scheduling algorithm(Cont.)
Scheduling the original network:
If nodes vi, vj in the linear network are assigned the same color, they do not interfere.
By construction of the linear network any two nodes in the original network, one chosen from level i and the other from level j, can transmit at the same time.
After determining the levels corresponding to the current time slot from the linear network coloring, a nonconflicting set of nodes at these levels that have packets to transmit are selected for transmission.
The algorithm is given in Fig. 4.

Multilevel queue scheduling
Based on foreground(interactive) processes and background (batch) processes multilevel queue scheduling partitions ready queues into several queues.
Each queue has its own scheduling algorithm.
scheduling among the queues, implemented as fixed-priority preemptive scheduling.

Considerations for choice (can be considered arbitrary) of wavelet function:
1) Orthogonal or non-orthogonal:
Non-orthogonal (like those shown here) are useful for time series analysis. Orthogonal wavelets (for signal processing –discrete blocks of wavelet power)– Haar, Daubechies
2) Complex or real:
Complex returns information on amplitude and phase; better adapted for oscillatory behavior.
Real returns single component; isolates peaks or discontinuities
3) Width (e-folding time of 0):
Narrow function — good time resolution
Broad function – good frequency resolution
4) Shape:
For time series with jumps or steps – use boxcar-like function (Haar)
For smoothly varying time series – use a damped cosine (qualitatively similar results of wavelet power spectra).

Good wavelets for compression
There are better filters than the “haar” filters
Want PR because energy compaction stages should be reversible
Wavelet filter design is art and science
Won’t go into this at all in this course
You will just be exposed to a couple of wavelets that are used in the literature
There are very many wavelets! Only some are good for compression and others for analysis
