A novel approach to mitigate IoT gateway disconnectivity using fallback mechanism

摘要

In the architecture of Internet of Things (IoT), gateway plays a critical role which provides connectivity to end nodes with the server/IT edge services. The server provides commands or necessary data to the gateways or vice-versa to drive particular IoT application. However, this scenario requires continuous connectivity of server and gateways for smooth functioning of the IoT system. Any attack or development mistakes on server may keep gateways starving for commands to be pushed to end nodes. This kind of scenario is critical to handle in industrial IoT because it deals with the critical infrastructure. In this paper, we are proposing a fallback mechanism (theoretical model) which can be incorporated within the IoT gateway to handle such disconnectivity issues of server to minimize the damage that can be caused to the complete system.
