Today ” internet”. The wireless sensor networks

Today the earth  is moving in building smart Cities and peopleneed  the world  on their hands, It outlets the revolutions ofcomputing  and smart environment . Internetof Things (IoT) is an excellent rising technology to influence the internet andcommunication technologies. Simply  “Internet of Things” connects  “living andnon-living things”  through  ” internet”.

The wireless  sensornetworks in smart  city architecturegenerated  large amount of data ineveryday in the different domains, with applications including  environmental monitoring, health monitoringand  vehicle monitoring. To takeadvantage of the increasing amounts of data there is a need for new methods andtechniques for effective data management, and analyse and generate theinformation that used to managing the utilization of resources konwledgablemanner and dynamically.This research represent, a Multi-Level Smart Cityarchitecture is proposed based on semantic web technologies . This explained interms of its concepts and some real-time context-aware scenarios. Traditionally in the object oriented paradigmeverything in the world is considered as an object, but in the IoT paradigmeverything in the world is considered as a smart object, and allows them tocommunicate to each other through the internet technologies by physically orvirtually. IoT is the network of physical objects-devices, vehicles, buildingsand other items embedded with electronics, software, sensors, and networkconnectivity-that enables these objects to collect and exchange data. In the2000s Internet connectivity became the norm for many applications and today isexpected as part of many enterprise, industrial and consumer products toprovide access to information.
