Abstract

Offloading computation to Mobile Edge Vehicular Clouds (MeVC) is an effective mechanism to meet the expectations of the \textcolor{blue}{next-generation} IoT networks. MeVC applications \textcolor{blue}{rely} heavily on resilient, trusted, and reliable wireless communication as a pillar to support its operation. This paper presents a software-defined, flexible vehicular Ad-hoc NEtwork (Sd-VANET) architecture that enables the construction of resilient network infrastructure and the secure operation of MeVC. The Sd-VANET is managed by a novel situation-aware blockchain-based framework that dynamically reprograms the network topology and data flows at run-time to enable Moving-target Defense (MtD) applications against attacks and failures. The presented solution was mathematically modeled and analyzed. Simulations showed that the proposed system can effectively and efficiently improve the quality of communication services and their resilience against attacks and failures.
