Abstract:

Recent technological advances have enabled tiny microsensors to do
reliable monitoring and control of a variety of applications. With ease of
deployment and cost-effectiveness, sensor networks represent a paradigm
shift in computing and sensing the environment without any human
intervention. In this talk, we discuss characteristics of different types
of sensors and provide an overview of how to get information from sensors.
Important design considerations of sensor networks are emphasized in terms
of energy efficiency and scalability and usefulness of multiple paths
routing in providing load balancing, and service differentiation is also
described.  We also consider effective ways of query processing in a
heterogeneous sensor network. Use of regression for data aggregation that
achieves desired degree of accuracy with just few coefficients, has also
been explored. The need for middleware to support execution of
sensing-based applications is also emphasized. Numerous future challenges
and potential applications of the technology, yet to be explored are also
presented.
