Data communication happens in every element of an IoT network, including the essential architectural elements such as IoT sensor devices, edge routers, and cloud services. Learn the data communication paradigms between these elements, and understand the small and big data operations in the edge and cloud computing concepts.
- [Instructor] We have seen some basic data communication…paradigms on the essential parts of our IoT system.…Now, we're going to take a look…at data communication paradigms…on end services, edge devices, and the cloud services.…Considering the possible broad spectrum…of technologies for each element,…we're only briefly exploring basic models here.…Let's first look in end device,…one that can form a network in the local network,…following a network topology such as a star,…extended star, or a mesh.…
The end devices basically can directly talk to each other…or they may also be able to communicate…with a local gateway or an edge router or both.…If there are two gateways or more,…the gateways may directly talk to each other…in order to exchange information…between the two networks.…Or if these two networks are connected…to our infrastructure network or backbone network.…They both can be connected through edge router…or some other network devices.…
The data communication in a local low-power wireless network…is a rich topic.…
