| l | Advantages |
|||||||||
| Ø | suitable for
the unpredictable nature of Ad-Hoc networks |
|||||||||
| Ø | suitable for
the requirement of quick reaction to QoS demands |
|||||||||
| Ø | makes call
admission control possible |
|||||||||
| Ø | avoids the
waste of network resources |
|||||||||
| l | Disadvantages |
|||||||||
| Ø | introduces
additional protocol overhead |
|||||||||
| Ø | trade-off
between the QoS performance and traditional protocol |
|||||||||
| performance |

QoS routing |
