摘要：Due to the recent developments in the handheld devices and communication enhancements in wireless networks like mobile adhoc 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 qualityofservice is required in these networks. In this thesis, we have proposed a delayaware routing protocol that discovers routes for a sourcedestination pair with the application provided delay constraints. The methodology is focused on using a reactive routing approach, AODV, to discover the delayaware routes during its route discovery phase; hence, our proposed protocol is called as DSAODV (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.
