1. Infrastructure breaks // Disaster areas
2. Expensive inconvenient time-consuming set up // Military
What are possible applications of infrastructure-free networks? [5]
1. Factory floor automation
2. Disaster recovery // In an avalanche
3. Car-to-car communication finding empty parking lot
4. Military networking between tanks, soldiers
5. Personal area networking
What are the characteristics of mobile wireless ad-hoc networks (MANET)? [4]
1. Without infrastructure using networking abilities of participants
2. Network “for a special purpose”
3. Expensive equipment
4. “Human in the loop” applications
What is the reaction on no central entity for MANET?
