Abstract

Abstract—This paper addresses the problem of enhancing video service quality for Mobile Ad Hoc Networks (MANET) scenarios. We offer Multipath Optimized Link State (MP-OLSR) routing protocol for H.264/SVC bitstream forwarding in the MANET network. Besides the usage of a suitable routing protocol, the video quality can be further enhanced by using the scalable encoding feature of Scalable Video Coding (SVC) combined with Unequal Error Protection (UEP). SVC is an extension of the H.264/AVC video compression standard used for high-quality video bitstreams encoding, providing spatial, temporal and quality scalability. To evaluate video quality, the Video Quality Metric (VQM) is used. We chose 5 different video contents for our simulations char-acterized by various temporal and spatial complexities. These video references are taken from the Video Quality Expert Group (VQEG). The results show that multipath routing combined with UEP can effectively improve the quality of video communication over MANET in terms of VQM and successful video decoding.
