Today the earth ismoving in building smart Cities and people need the world on their hands, Itoutlets the revolutions of computing andsmart environment . Internet of Things (IoT) is an excellent emergingtechnology 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 inSmart City infrastructures have very large amounts of data being generated everyday in different types of domains, withapplications including environmentalmonitoring, healthcare monitoring and transport monitoring. To take advantageof the increasing amounts of data there is a need for new methods andtechniques for effective data management and analysis to generate information that can assist in managing theutilization of resources intelligently and dynamically. This research represent, a Multi-Level SmartCity architecture is proposed based on semantic web technologies . Thisexplained in terms of its concepts and some real-time context-aware scenarios. Traditionallyin the object oriented paradigm everything in the world is considered as anobject, but in the IoT paradigm everything in the world is considered as asmart object, and allows them to communicate to each other through the internettechnologies by physically or virtually.
IoT is the network of physicalobjects-devices, vehicles, buildings and other items embedded with electronics,software, sensors, and network connectivity-that enables these objects tocollect and exchange data. In the 2000s Internet connectivity became the norm formany applications and today is expected as part of many enterprise, industrialand consumer products to provide access to information. The main features of a smart city include ahigh degree of information technology integration and a comprehensiveapplication of information resources. The essential components of urbandevelopment for a smart city should include smart technology, smart industry,smart services, smart management and smart life.
