Sensor Networks
Today,
hundreds of millions of sensors are deployed in our environment. This includes
cameras on myriads of cell-phones, ubiquitous indoor temperature sensors,
garage-door motion sensors, web cams in public spaces, among others. Hardware
miniaturization and wireless communication advances suggest increased
proliferation of sensing devices and their integration into wireless sensor
networks for myriads of urban, military, social, and medical applications.
Zigbee, Bluetooth and other wireless technologies present possible options for
the interconnection of sensors. Research on sensor networks investigates
network protocols, services, resource management, and programming paradigms
tailored to the new environment.
Applications:
·
Military and national security: Remove surveillance, monitoring,
infrastructure protection.
·
Environmental: Understanding natural phenomena,
monitoring and protection against adverse conditions (e.g., forest fires,
hurricanes, etc).
·
Medical: Human monitoring, reducing the cost
of healthcare, automated assisted living.
·
Ubiquitous computing: Smart spaces, homes, airports,
hospitals, collaboration tools, social applications, cyber-physical
communication media.
·
Industrial: Supply chain monitoring, factory
automation, embedded computing and control
Research Challenges:
·
Theory
and new models of computation
·
Programming
abstractions and tools
·
