Video streaming over MANETs: An overview of techniques

Mobile Ad-hoc NETworks (MANETs) allow wireless networks to exist where there is no or limited network infrastructure. They have attracted renewed attention as part of the 5G approach to device densification, while they remain very relevant to natural disaster response. The reader will benefit from the techniques concentrated upon in this overview article, in particular Multiple Description Coding (MDC) or Scalable Video Coding, with multipath delivery, with which it is feasible to stream video across MANETs. However, the article's two case studies demonstrate that video quality and Quality of Experience (QoE) depend on node density and node speed within a MANET. Higher node speeds are also relevant to Vehicular Ad Hoc Networks (VANETs) and Vehicle to Everything (V2X) technology, which the article also touches upon. This overview identifies the key concepts involved in video streaming over MANETs and VANETs, including as well a large number of relevant references.
