As the report is designed mainly for the spread spectrum techniques

course, the protocols in the lower level are described more

extensively and the upper layer protocols are just mentioned with a

very brief description.

Moreover, one should note that the upper layer protocols are totally

dependent on the lower level protocols whereas the lower level

protocols can function independently even with a totally dierent

set of upper protocols.
