Application Domain of Wireless Sensor Network-A Paradigm in Developed and Developing Countries
Wireless sensor networks are network of small sensing
devices, which collaborate with each other to gather
process and communicate over wireless channel
information about some physical phenomena. These
self-organizing, highly robust and energy efficient
networks can be excellent sentinels for monitoring
underground mining, wildlife and various physical
infrastructures such as bridges, pipelines, and
buildings. The smart sentinels go by the name wireless
sensor networks and interface the physical world with
computers, thereby creating a profound flexibility for
awareness and remote controlling. They are
characterized by their little demand for attention from
human operators, their capability of self-management;
operation in adverse places and near the occurrence of
the actual phenomena; great accommodation of node
mobility or failure; and effective node cooperation in
order to carry out a distributed sensing task. But the
fact that most previous research revolved around
military applications. Sensors integrated into structures,
machinery, and the environment, coupled with the
efficient delivery of sensed information, could provide
tremendous benefits to society. Potential benefits
include: fewer catastrophic failures, conservation of
natural resources, improved manufacturing
productivity, improved emergency response, and
enhanced homeland security.
