Edge Computing

IoT receives much industry and economic focus because of the number of devices that will eventually be deployed and the amount of data those devices will produce. There are two methods regarding how edge devices and sensors will operate and communicate with the internet:

• Edge-level sensors and devices will provide a direct path to the cloud. This implies that these edge-level nodes and sensors will have enough resources, hardware, software, and service-level agreements to transmit data across the WAN directly.
• Edge-level sensors will form aggregations and clusters around gateways and routers to provide staging areas, protocol conversions, and edge/fog processing abilities, and they will manage security and authentication between ...
