Inter of thing is the most immerging technology these days. The course basically gives you the introduction of basic architecture of IoT and how these components of IoT are connected to each other through some communication Protocol. The basic few Protocols in Wireless Personal Area Network (WPAN) used in IoT are covered in this course. These various protocols are used in developing an IoT application. You will get the basic knowledge of various protocols which can be used in various layers or IoT stack. Communication Protocol used in IoT come under WPAN and have limited range of Communication. After studying select the protocols for the an IoT applications based on the layer that is IoT Stack it is been used and the power availability. Protocols play an important role in design of a IoT system. The Big data which is generated is transferred to cloud services using some communication protocol only from things to the user. The course is designed for the bingers in the field of inter net of things (IoT), and how communication is possible in IoT enabled devices. After studying this course one can easily compare the various protocols and select the protocol depending of the design of an IoT system.
