Abstract

Improving the security and availability of secure wireless multimedia systems is the purpose of this thesis. Specifically, this thesis answered research questions about the capacity of wireless multimedia systems and how three variables relate to this capacity. The effects of securing the voice signal, real-time traffic originating foreign to a wireless local area network and use of an audio-only signal compared with a combined signal were all studied. The research questions were answered through a comprehensive literature review in addition to an experiment which had thirty-six subjects using a secure wireless multimedia system which was developed as part of this thesis effort. Additionally, questions related to the techniques for deploying wireless multimedia system including the maturity and security of the technology were answered. The research identified weaknesses in existing analytical and computer models and the need for a concise and realistic model of wireless multimedia systems. The culmination of this effort was the integration of an audio-video system with an existing research platform which is actively collecting data for the Logistics Readiness Branch of the Air Force Research Laboratory.
