Abstract

Topology change and nodes move in Ad Hoc networks leads to regular interruption of the path, making Ad Hoc network channel bit error rate and transmission packet loss rate very high. This brings a new challenge for video transmission. As a result, research on video coding and transmission methods that suitable for Ad Hoc networks has become a hot spot today. On the basis of transmission characteristics of Ad Hoc networks, it starts with video encoding, video transmission and the receiver all together, gives a systematic introduction to the current research status and main methods of video transmission in Ad Hoc networks, moreover forecasts the future of the key technologies and new mechanisms which are suitable for video transmission in Ad Hoc networks.
