Today to communicate to each other through

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 ideal emerging
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.
