The authors details the concept of smart city, IoT based smart city model and cloud computing model. 6LowPAN, RPL, CoAP are the proposed several protocols for resource constrained devices by IETF. IoT connects the physical infrastructures to digital world and makes the task of city easier and efficient. The cloud computing architecture consists of master nodes directory, data center nodes, set-top box node and nodes on other connected devices. Data in master nodes are well protected and can be accessed from anywhere by the connected devices. Transportation, healthcare, buildings, telecom, utilities, tourism, education are the applications of IoT based smart cities used in Dubai in cloud platform. In addition, the researchers proposed PaaS and IaaS fo IoT based healthcare framework. |
