Today of its concepts and some real-time context-aware

Today the earth  is
moving in building smart Cities and people need 
the world  on their hands, It
outlets the revolutions of computing  and
smart environment . Internet of Things (IoT) is an excellent rising technology
to influence the internet and communication technologies. Simply  Internet of Things connects  living and non-living things through  internet. The latest implement of wireless
sensor networks in Smart City infrastructures have very large amounts of data
being generated everyday  in different
types of domains, with applications including 
environmental monitoring, healthcare monitoring and transport
monitoring. To take advantage of the increasing amounts of data there is a need
for new methods and techniques for effective data management   and analysis to generate information that
can assist in managing the utilization of resources intelligently and
dynamically.   This research represent, a
Multi-Level Smart City architecture is proposed based on semantic web
technologies . This explained in terms of its concepts and some real-time  context-aware scenarios. Traditionally
in the object oriented paradigm everything in the world is considered as an
object, but in the IoT paradigm everything in the world is considered as a
smart object, and allows them to communicate to each other through the internet
technologies by physically or virtually. IoT is the network of physical
objects-devices, vehicles, buildings and other items embedded with electronics,
software, sensors, and network connectivity-that enables these objects to
collect and exchange data. In the 2000s Internet connectivity became the norm for
many applications and today is expected as part of many enterprise, industrial
and consumer products to provide access to information. The main features of a smart city include a
high degree of information technology integration and a comprehensive
application of information resources. The essential components of urban
development for a smart city should include smart technology, smart industry,
smart services, smart management and smart life.
