Many warfighters and first responders operate at what we call "the tactical edge," where users are constrained by limited communication connectivity, storage availability, processing power, and battery life. In these environments, onboard sensors are used to capture data on behalf of mobile applications to perform tasks such as face recognition, speech recognition, natural language translation, and situational awareness. These applications then rely on network interfaces to send the data to nearby servers or the cloud, if local processing resources are inadequate. While software developers have traditionally used native mobile technologies to develop these applications, the approach has some drawbacks, such as limited portability. In contrast, HTML5 has been touted for its portability across mobile device platforms as well an ability to access functionality without having to download and install applications. In this podcast, Grace Lewis describes research aimed at evaluating the feasibility of using HTML5 to develop applications that can meet tactical edge requirements.
Grace A. Lewis is the deputy lead for the SEI's Advanced Mobile Systems
initiative and the technical lead for the Edge-Enabled Tactical Systems
research team, which works on a number of projects related to mobile
systems at the edge. Her main interests are mobile computing,
service-oriented architecture, and cloud computing. Lewis has more than
20 years of professional software development experience, mainly in
industry. Before joining the SEI, Lewis was chief of systems development
for Icesi University, where she served as project manager and technical
lead for the university-wide administrative systems.
