Today virtually. IoT is the network of physical

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 wireless  sensor networks in
smart  city architecture generated  large amount of data in everyday in the
different domains, with applications including 
environmental monitoring, health monitoring and  vehicle 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.
