Optimal Secure Multi-Layer IoT Network Design

Abstract : With the remarkable growth of the Internet and communication technologies over the past few decades, Internet of Things (IoTs) is enabling the ubiquitous connectivity of heterogeneous physical devices with software, sensors, and actuators. IoT networks are naturally multi-layer with the cloud and cellular networks coexisting with the underlaid device-to-device (D2D) communications. The connectivity of IoTs plays an important role in information dissemination for mission-critical and civilian applications. However, IoT communication networks are vulnerable to cyber attacks including the denial-of-service (DoS) and jamming attacks, resulting in link removals in IoT network. Therefore, it is important to maintain the connectivity of IoT networks and make them secure and resistant to malicious attacks. In this work, we present a heterogeneous IoT network design problem in which a network designer can add links to provide additional communication paths between two nodes or secure links against failures by investing resources. We characterize the optimal strategy of the secure network design problem by first providing a lower bound on the number of links a secure network requires for a given budget of protected links, and then developing a method to construct networks that satisfy the heterogeneous network design specifications. Case studies on the Internet of Battlefield Things (IoBT) are used to corroborate our results.
