Wireless Sensor Research Lab

 

IIIT-Hyderabad, India

 

I. Ubiquitous sensor network

This is a network that enables users to receive necessary information anytime, from anywhere by installing small wireless sensors that detect surrounding environment such as temperature, humidity and vibration in buildings, roads, mountains, rivers, etc. Usually these devices are small and inexpensive, so that they can be produced and deployed in large numbers, and so their resources in terms of energy, memory, computational speed and bandwidth are severely constrained.

Protocols developed within the WSN Lab are typically tested through simulation and/or implementation. To facilitate testing, we have plans with AirBee Wireless to created a testbed consisting of a heterogeneous assortment of wireless devices.

 

Research Issues:

 

How to organize multi-hop and clustering protocols for WSNs?

 

Challenges:

 

Extending the maximum life-span of the multi-hop sensor networks which are constrained with non-replishnable energy sources

 

Implementation/Simulation:

 

Provide test bed for gathering results of power aware routing and data fusion techniques in cross layer data aggregation

 

      Current Research Interest

 

  •       Design of power-aware routing algorithms
  •       Fault tolerant fusion algorithms

 

II. Department of Science and Technology (DST)

 

Duration of project is 2006-2008 for a total funding of 11 Lacks.
