Global Sensor Network is built for :

  • A.Reducing cost and time for development
  • B.Reducing cost and increasing time for development
  • C.Increasing cost and increasing time for development
  • D.Increasing cost and decreasing time for development

Answer: A

Global Sensor Network is built for reducing cost and time for development.

GSN is an open-source middleware platform for sensor networks developed at EPFL. Its design goal is to make deploying and programming sensor networks quick and cheap: sensors and data streams are described declaratively in XML 'virtual sensor' files and processed with SQL-like queries, so new sensors and applications can be added without writing low-level code. Its authors present it as reducing the cost and time of developing sensor network applications.

Any middleware aims to cut development effort, so options that increase cost, increase development time, or both, run against the purpose of the platform.
