Abstract:-  Due to the recent developments in the hand-held devices and communication enhancements in wireless networks like mobile ad-hoc network (MANETs), these networks are targeted for providing real time services like video streaming, video conferencing, VOIP etc. Although, the basic design of MANETs is not fully capable to provide multimedia services, therefore some sort of quality-of-service is required in these networks. In this thesis, we have proposed a delay-aware routing protocol that discovers routes for a source-destination pair with the application provided delay constraints. The methodology is focused on using a reactive routing approach, AODV, to discover the delay-aware routes during its route discovery phase; hence, our proposed protocol is called as DS-AODV (Delay Sensitive AODV). In this way, we are able to provide the QoS to the requesting application in terms of delay metric. The delay constraint provided by the application that wishes to transmit its traffic is used to find suitable routes that can send the application traffic from source to destination node within the specified delay bound. Simulation results are developed using the trial version of” Exata Cyber” network simulator and analyzed to show the effectiveness and correctness of the proposed method.
