Proactive QoS Routing
nAdvantages
Øsuitable for the unpredictable nature of Ad-Hoc networks
Øsuitable for the requirement of quick reaction to QoS demands
Ømakes call admission control possible
Øavoids the waste of network resources
nDisadvantages
Øintroduces
additional protocol overhead
Øtrade-off
between the QoS performance and traditional protocol performance
But..
Little work has been done
to analyze the impact of the additional overhead on pro-active QoS routing
