SVC-based video streaming over highway vehicular networks with base layer guarantee

Abstract

In this paper, we target the resource allocation and layer selection problem for the realtime video streaming over highway scenario, by employing Scalable Video Coding (SVC) for the video contents. Especially, we take the freeze-free playback as one of the constraint as well. Since the formulated resource allocation and SVC layer selection problem is NP-hard, we propose the Resource Allocation and Layer Selection with Base layer guarantee (RALSB) algorithm to solve this problem in two phases: the Base layer Guarantee (BG) phase, and the Resource allocation and SVC layer selection (RS) phase. Simulation results show that the proposed RALSB can prevent/reduce the playback freeze in typical scenarios.
