Advantages and applications<br />
<strong>Mobile</strong> <strong>ad</strong>-<strong>hoc</strong> <strong>networks</strong>: Advantages<br />
Simple, fast and cheap setup of <strong>networks</strong><br />
e.g. with 802.11b in the 2.4 GHz (ISM) band: no license required<br />
transmit power can be reduced compared to wireless infrastructure <strong>networks</strong><br />
distance to nearest neighbor can be lower than to the base station<br />
More robust concerning failure of single components due to decentralized structure<br />
Military applications<br />
formations of soldiers, tanks, planes,...<br />
Civil applications<br />
conferences, exhibitions, meetings, lectures<br />
telematics applications in traffic<br />
Extension of cell-based systems (WLAN, UMTS)<br />
Entertainment on travels (file sharing, gaming,... in trains, cars or planes)<br />
sport events<br />
<strong>networks</strong> for cabs, police,…<br />
sensor <strong>networks</strong><br />
In case of disasters<br />
<br />
<br />
In case of infrastructure failure (telephone network,..): e.g. earthquakes<br />
rescue operations, e.g. after avalanches<br />
