Iot Architecture: A Survey

The Internet of Things, popularly known as IoT, is not a far-fetched dream any more. With the arrival of ireless sensor networks and technologies such as the RFID tags and embedded sensors and actuator nodes the ability to measure, infer and understand environmental indicators is something which is reaching new heights. The rise of these devices in a communicating-actuating network creates the Internet of Things (IoT) in which the sensors-actuators act as the tangible components which help in realizing the environment around us. Like all network communications this integration of things also requires a specific protocol and architecture that needs to be followed. This IoT architecture, like the Internet, will supposedly grow in evolutionary fashion from a variety of separate contributions, rather than from a single unique plan. This paper in principle throws light on this opaque vision of IoT architecture and further moves onto reviewing the need of a concrete architecture, its architectural elements, the architectural scheme and finally a look at certain architectural issues that have canvassed this scenario.
