Wireless Sensor Networks: Motivation, Progress, and Challenges

Speaker:  Tracy K Camp – CO, United States
Topic(s):  Architecture, Embedded Systems and Electronics, Robotics

Abstract

Wireless sensor networks are improving our world in numerous ways, from environmental monitoring to inventory tracking to health applications to surveillance. These networks connect our physical world with our digital world, and provide us with both a richer understanding of our environment and the ability to more accurately control our surroundings. The capability for detailed physical monitoring and adaptation offers tremendous opportunities for almost every science and engineering field. There are, however, many technological hurdles that we must solve in order to continue "instrumenting the world" with wireless ad hoc sensor networks. For example, individual sensor devices are incredibly resource constrained, including limited processing power, limited storage capacity, limited communication bandwidth, and limited energy. Thus, new hardware and software designs are needed to maximize the capabilities of a wireless sensor network while minimizing the cost to deploy and maintain.

In this presentation, I will provide an overview of this emerging field of research. I will describe the history of research in this area, the current state-of-the-art, the diverse problems that researchers are presently tackling, and the open research questions that continue to exist. These open research questions require innovative solutions for several years to come. I will also present the current research directions of my group in this area. For example, in conjunction with geophysicists and environmental engineers, we are developing wireless sensor networks to allow a geosystem to sense its environment and adapt to improve performance.
