MOBILE AD HOC NETWORK MEDIA AWARE NETWORKING ELEMENT
First Claim
1. A method for controlling video stream distribution in an ad hoc network, comprising:
- receiving, by a first network node, a first video stream having a Scalable Video Codec (“
SVC”
) format and a first data transfer rate, the first network node residing between a video source device and a video destination device;
determining, by the first network node, a second data transfer rate for the first video stream based on one-hop throughput conditions of a communications link between the first network node and a second network node downstream and one-hop away from the first network node; and
transferring the first video stream from the first network node to the second network node at the second data transfer rate which was previously determined, whereby any link quality impediments within the ad hoc network are resolved locally at the first network node.

Abstract
Systems (100) and methods (200) for controlling video stream distribution in an ad hoc network. A first network node (116 or 120) receives a first video stream (108) having a Scalable Video Codec format and a first Data Transfer Rate (“DTR”). The first network node resides between a video source device (102/106) and a video destination device (124, 128 or 132). The first network node then determines a second DTR for the first video stream based on conditions of communications links between the first network node and at least one second network node (118, 120, 126 or 130) downstream from the first network node. The first video stream is transferred from the first network node to the second network node at the second DTR which was previously determined, whereby any link quality impediments within the ad hoc network are resolved locally at the first network node.
