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

·          Distributed operating systems for deeply embedded computing

·          Privacy and security

·          Middleware and deployment tools

·          Data scavenging, opportunistic mobility models and data hitchhiking

·          Energy management

·          Communication protocols (a network architecture for sensor networks)
