A survey on IoT architectures, protocols, security and smart city based applications

Abstract

Evolving methodologies are seamlessly connecting the real world and the virtual world using some physical objects and intelligent sensors. Internet of Things (IoT) is one such methodology. Things are becoming smarter than before. IoT empowers users to communicate and control physical devices to salvage vital information. Large amounts of data will be generated and exchanged which in turn will help in decision making. This survey paper describes the architecture of IoT, protocols used in IoT, its security issues and smart city based IoT applications.
