IoT and its Smart Applications
Due to the raid growth of computing technology in last two decades, human effort of doing any works has drastically reduced. One of the most emerging areas in the field of computing technology is IoT which has completely changed human's life style. IoT is a sort of "universal global neural network" in the cloud which connects various things. Things define object or entity which has physical existence. So, IoT defines the use of intelligently connected devices and systems to leverage data gathered by embedded sensors and actuators in machines and other physical objects. The term, IoT although coined way back in 1999 by Kevin Ashton in the context of supply chain management, but it became popular after the onset of RFID (Radio Frequency Identification) Currently there are 9 billion interconnected devices and it is expected to reach 25 billion devices by 2020. Due to this rapid growth, it gained a great attention from the researchers. Several research works have conducted to create different smart applications using IoT such as smart supply chain management, Smart grid, Smart energy consumption, Smart transportation, smart waste management and monitoring system and etc. Now the next revolution will be the interconnection between objects to create a smart world in every aspect. In this paper,I review a concept of many IoT applications and future possibilities for new related technologies in addition to the challenges that facing the implementation of the IoT.
