Course Description:

In the last 15 years, several technology trends have influenced the field of geosciences in significant ways. The first trend is the more readily available technology of ubiquitous wireless communication networks and progress in the development of low-power, short-range radio-based communication networks, the miniaturization of computing and storage platforms as well as the development of novel microsensors and sensor materials. All three trends have changed the type of dynamic environmental phenomena that can be detected, monitored and reacted to. Another important aspect is the real-time data delivery by novel platforms today. In this course, we will survey the field of geosensor networks, and mainly focus on the technology of small-scale geosensor networks, decentralized ad-hoc, in-network computing and collaboration, example applications and their feasibility and lessons learned as well as the current research questions posed by using this technology today.

For an introduction to geosensor networks, pleaseĀ see this paper.

Topics covered:

  • Motivation, history and vision
  • Platforms
  • Data-centric routing in geosensor networks
  • Data collection, queries and data analysis in geosensor networks
