Inthispaper, wepresentanadmissioncontrolwithmulti-pathroutingalgo-rithm that establishes QoS enabled label switched paths. The algorithmprovides rigorous QoS provisioning within the Differentiated Services(DiffServ)enabledmobilead-hocnetwork.Theproposedschemeworksbymerging the signaling with the routing messages. It directs QoS sensitivetraffic on multiple paths provided that each path satisfies the QoS require-ments of a flow. Decision for granting admission to the flow depends upontotal available bandwidth (considering the interference range), minimumdelay required by an application, and delay offered by the network in agiven DiffServ class. Extensive simulations are performed to measure theeffectiveness of the presented idea. It is observed that our scheme meetsstringent QoS requirements of real time flows compared to the existingQoS models. Each admitted flow gets low delay, low jitter and almostguaranteed bandwidth.
