US 2017/0013533 A1 · SYSTEM, APPARATUS AND METHOD FOR ROBUST TRANSMISSION OF VISUAL DATA THROUGH VISUAL SENSOR NETWORK

Abstract

The present invention is related to a method for routing image data from Camera Node to a Sink Node, where it May be processed in detail, in a Visual sensor network. In accordance with the present invention, wireless Intermediate Node are configured to route images based on first pass image encoding containing coarse image to the next wireless hop at a higher priority over the images based on the second pass encoding containing additional details of the images. The routing method for wireless Ad Hoc mobile and sensor network, periodically exchanges node status information to optimize the routing table, so that high priority image packets may reach the Sink Node in shortest possible path. The method ensures selection of high quality image packets for routing under the condition of collision and congestion to achieve optimal image quality receipt at the Sink Node.

Dependent claims

An apparatus, comprising:

a visual sensor network with a hardware and a software;
a Camera Node to capture, prioritize, layer, package and transmit an image;
an Intermediate Node to receive the captured image, prioritize the queue, calculate next hop and transmit the image;
and
a Sink Node to receive a processed, prioritized, captured and queue an image as a priority package.

2 more elements

A method of using a visual sensor network, comprising:

procuring an image using a Camera Node as a captured image;
wherein the Camera Node may be present in wireless Ad Hoc network, mobile and wireless sensor network;
layering and compressing the captured image into a most prominent to a least prominent feature data;
performing several passes to create a layered encoded image on the most prominent featured data and creating a first pass coarse encoded image as a high priority image and a secondary pass coarse encoded image as a low priority image;
packetizing and prioritizing the most prominent to the least prominent feature data of the first pass coarse encoded image and the secondary pass coarse encoded image to be passed on to an Intermediate Node.
