Proactive QoS Routing
lAdvantages
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
lDisadvantages
Øintroduces additional protocol overhead
Øtrade-off between the QoS performance and traditional protocol performance
But..                                           
lLittle work has been done to analyze the impact of the additional overhead on pro-active QoS routing
