On the software architectures for fog-based secure IOT deployments

Abstract

In this paper, we examine architectural designs for the support of demanding ad hoc IoT applications, such as industrial and large-scale IoTs. First, we examine the traditional software stack of nodes involved in centralized sensory applications. Then, we propose a highly distributed ad hoc architecture with increased node cooperation. Finally, we propose a secure fog-based hybrid model that offers optimizations with respect to performance and security and which facilitates the development of intelligent localized end-user applications with very strict latency requirements. In the three models that we examine we highlight operations at the routing layer and at the clustering sub-layer.
