In recent years, the United States Armed Services and various law enforcement agencies have shown increasing
interest in evaluating the feasibility of using smartphones and hand-held devices as part of the standard gear for its
personnel, who are actively engaged on battlefield or in crime-prone areas. The primary motive driving analysis
efforts to employ smartphone-based technologies is the prospect of the increased "Situational Awareness"
achievable thru a digitally connected network of armed personnel. Personnel would be equipped with customized
smart applications that use the device's sensors (GPS, camera, compass, etc...) to sense the hostile environments as
well as enabling them to perform collaborative tasks to effectively complete a given mission. In this vein, as part of
the Summer At The Edge (SATE) program, a group of student interns under the guidance of mentors from Qbase
and AFRL, have employed smartphones and built three smart applications to tackle three real-world scenarios:
PinPoint, IStream, and Cooperative GPS. This paper provides implementation details for these prototype
applications, along with the supporting visualization and sensor cloud platforms and discusses results obtained from
field testing of the same. Further, the paper concludes by providing the implications of the present work and insights
into future work.
