Description

Current events have demonstrated a need for effective & persistent monitoring of secure areas, structures, and/or assets. But how, and with what approach? Significant advances have availed themselves regarding the design & development of capable Wireless Sensor Network (WSN) systems via the recent confluence of relevant technologies. WSN, a specialized subset of the Internet of Things (IoT), has repeatedly demonstrated outstanding capability & versatility in achieving autonomous & cost-effective remote sensing. Through ever-evolving WSN systems, more and more endeavors associated with data acquisition and observations can be deployed worldwide without observers or control centers in proximity.

 

Using WSN, both military & non-military surveillance, reconnaissance, and target tracking have reached impressive levels of measurement granularity. With the availability of a dense sensor fabric through WSN systems, highly-defined mining of valuable data has been achieved by those involved in threat assessment, force projection analyses, as well as surveillance of areas of interest (AOI). For the military, WSN represents a viable approach to distributed persistent sensing anywhere in the world.  For commercial ventures, WSN systems have been, and continue to be, successfully implemented to conduct cost-effective worldwide tracking and/or assessment of various items and/or properties.

 

The course is based on the text, Designing Wireless Sensor Solutions for Tactical ISR [Artech House publishing, 2020]. Similar to the text, the course is structured using a “system engineer (SE) perspective -- think system design, product realization, and technical management processes (ref. NASA System Engineering Handbook SP-2016-6105 Rev2, INCOSE Systems Engineering Handbook, 5th Edition).  This course addresses sensor node design, system development processes, WSN node subsystems, and methodologies to model, evaluate, predict system performance, conceptual design phase -to- operating system product (a-to-W) process. Topics are introduced, equations derived, and actual implementations presented to define:

  • Processes behind defining & revising mission objectives
  • Derivation of responsive system requirements
  • Physical characteristics involved (e.g., RF propagation, sensor principles)
  • Reviewing mathematical approaches to RF, sensor, & system performance modeling
