Title Using Multimedia Metadata to Improve Network Efficiency.
Publication Date Sep 2012

Personal Author J. D. Blocker
Abstract A growing amount of multimedia information exists online, and it is commonly referred to as the multimedia explosion. Many research efforts are focused on the concept that computing is ubiquitous and that accessing network resources is not the challenge, but rather finding the right object is. However, America's military and other first responder organizations often find themselves in austere environments where access to high-speed network resources is scarce, users only have access to low-bandwidth channels, and where every bit transmitted has to count. In this thesis, we design a unique Lead-Me protocol that addresses both network access and finding the right data. It focuses on maximizing network efficiency by utilizing metadata information commonly found within multimedia files. We start by exploring other techniques commonly used to improve network efficiency, and then move to develop a protocol that fills the gaps. We use an intelligent middleware server that the client communicates to, direction-of-travel-aligned bounding boxes, and mashup technology to reduce the size of the file the client receives as a response, and optimization techniques to prevent the client from receiving redundant files. We show an increase in efficiency of over 99% by using the middleware server, and an increase of 11% using the optimization techniques.
