6. Highly performing network
No expensive infrastructure must be installed
Use of unlicensed of information around
sender
No single point of failure
7. No central entities=> operation in completely
distributed manner.
Network function must have high degree of
adaptability.
All network entities may be mobile => very
dynamic topology.
