Congestion may occur between the host and the fog node due to increased traffic . “More infrastructure is needed and you are relying on data consistency across a large network,” he said. It can become a complex issue for brands to handle, as data sets that require more sophisticated algorithms are better handled in the cloud, whereas simpler analytical processes are best kept at the edge.

Future work could lead towards the development of a knowledge-based supplementary and aid system, which can provide decision support services for developers in designing a secure and performance efficient Fog infrastructure. Such a decision support system would require a large systematic knowledge acquisition of best practices, known security threats and their solutions, which can be formalized as either statistical-based system or rules, policies and facts . The system would also require an inference engine that can provide and explain suitable solution or advice, considering the given application scenario and available knowledge. A Fog platform is connected with both end-users and Cloud platform along with processing, storing and transmitting large volumes of data by consuming limited amount of resources.

Processing and storing data in the local network in combination with the cloud . The fog model pertains to the massive amounts of data generated by sensors in machine-to-machine computing .
