Abstract
Vehicular ad-hoc networks play quite an important role in communication as it is challenging to have communication across VANET nodes because of high mobility. Video streaming applications over ad-hoc networks are quite difficult because of more mobility of VANET nodes. There are various existing techniques to optimize or improve the video dissemination over ad-hoc networks. Video streaming applications need a good quality of service in ad-hoc networks for better streaming. To optimize the performance of video streaming applications over Vehicular ad-hoc networks, a hybrid routing protocol, which is an advancement of existing routing protocol namely, AODV is proposed. It has shown better performance in terms of Peak Signal to Noise Ratio for video streaming simulated as VBR, CBR and VOIP traffic has been analyzed. This paper compares performance metrics on AODV routing protocol and proposed R-AODV where predicted lifetime metric is used as a crucial factor for route stability. The simulation and test results show that there is an articulate improvement observed in terms of application layer metrics and network layer metrics. Results show that there is a lesser number of link failures and RERR messages generated. PSNR gains have also been evaluated. The advantage of this technique is that it has got no overhead as the information retrieved is based on the RERR messages itself.
