Abstract

This paper proposes a method to realize a reliable live video streaming over mobile ad hoc networks (MANETs) consisting of several Wi-Fi Direct groups. The proposed method uses a multi-path routing with two disjoint routes connecting a source to several subscribers so that if the primary route temporally becomes unavailable, the source immediately switches to the secondary route, which is regarded as a new primary route, and starts the exploration of a new secondary route by invoking a variant of AODV protocol. The result of experiments with twelve Android tablets indicates that it could stably deliver a live video stream of QVGA quality to a subscribing node located at 200 m away from the source node, and quickly recovers from link failures in 100 ms which is significantly shorter than the original AODV.
