摘要：
Ad Hoc networks utilize multi-hop radio relay without the need for a base station, supporting mobility and allowing them to be quickly deployed in an emergency. Real-time video communication across an ad hoc network allows helpers to better understand the nature of the problem within a disaster area but the lack of centralized routing and network resource management is challenging, particularly if the wireless nodes have limited processing power. Multi-path solutions have been proposed for video transfer. This paper investigates two practical schemes, Video Redundancy Coding and a proposal of the paper, H.264 codec redundant frames. The paper reports that redundant frames when used in combination with multipath do result in as much as 10 dB improvement in delivered video quality, making the difference between acceptable and unacceptable visual communication in a disaster scenario. © 2009 ACADEMY PUBLISHER.
