Optimal Multipath Routing for Video Transmission in VANETs

Abstract

The communication among the vehicles in Vehicular Ad Hoc Network (VANET) plays a major role in the improvement of safety in critical situations of road scenario. With the implementation of VANET, the transmission of videos to other vehicles is done in an improved way. A new algorithm, known as Moth Whale Optimization Algorithm (MWOA) is proposed in this paper to determine the optimal multipath for the transmission of the videos from one vehicle to other in the VANET network. The proposed algorithm is developed with the integration of Moth Search (MS) algorithm and Whale Optimization Algorithm (WOA). Initially, the VANET is simulated and the optimal selection of the multipath is done using adaptive geographic routing scheme based on the fitness measure. The performance of the proposed Moth Whale Optimization Algorithm is estimated with the metrics, such as Packet delivery Ratio (PDR), Packet end-to-end delay, and the throughput. The Moth-Whale Optimization Algorithm produces the minimum end-to-end delay of 4.4427, and maximum Packet delivery ratio and throughput of 96.5135 and 94.2429, respectively, which shows the superiority of the method in effective video transmission.
