The Internet-of-Things (IoT) constructs a vast, intricate, and perpetually evolving ecosystem exerting profound societal implications. This labyrinthine nature often culminates in errors that directly impact human lives. A significant domain where this complexity materializes is Intelligent Transportation Systems (ITS). Present tools and methodologies inadequately accommodate the complex task of testing and validation, underscoring the urgency for comprehensive review and enhancement. This study aims to present a broad analysis of existing simulators utilized for ITS simulations. It delves into the role and effectiveness of such simulation tools, highlighting their limitations and proposing research directions. This paper scrutinizes both commercial and research-oriented IoT simulators for ITS, evaluating their features and simulation environment tools. We have detailed various ITS scenarios simulated within these frameworks, intending to gauge their readiness for real-world ITS applications and to elaborate on the challenges involved in ITS infrastructure implementation. The findings suggest that despite numerous simulators aiding the evolution of solutions for IoT challenges in recent years, their utility in actual ITS implementations remain uncertain. Consequently, we explore public cloud platforms offering IoT simulation capabilities, focusing particularly on the capabilities provided by the Amazon Web Services (AWS) IoT simulation for this study. Our research outlines the pressing challenges in this field, while proposing potential solutions and flagging opportunities for further research. This study paves the way towards improving the reliability and accuracy of IoT simulators in the context of ITS, which has immense potential to enhance the quality of human life.

“…It should be noted that the operating systems and communications protocols used by these gadgets are usually designed to have minimal footprint. ContikiOS [6] and TinyOS [7] are two popular IoT operating systems that have their respective open source RPL implementations [8] as lightweight communication protocol for IoT devices that became a standard by IETF [9].…”

In domains such as telehealth, intelligent transportation, and autonomous agriculture, ensuring secure routing of collected and exchanged data is paramount. Since its inception, there have been many research challenges for the RLP routing protocol that operates in resource-constrained environments and utilizes battery-powered IoT devices. Hence, researchers have focused on this crucial challenge by advising solutions to mitigate attacks that deplete nodes' energy and hence create energy gaps in the network. In this article, we study the impact of two energy exhaustion attacks (hello flooding and version number modification) on the RPL protocol and we present a novel mitigation solution based on behavioural trust. We present an in-depth study of the impact on radio energy consumption of the hello flooding and version number modification attacks in RPL as the number of network nodes increases. We showed that the impact of the former is localized to nodes in the vicinity of the attacker while the latter has a global impact that extends to the entire network. The obtained results from our simulations show that version number modification attack in particular has devastating impact on the network. We also propose a trust-based solution to mitigate these attacks and demonstrate its effectiveness. Accordingly, we conduct comparative study of these attacks and empirically investigate their impact on network performance by running extensive evaluation experiments. Our findings verify the effectiveness of our proposed trust system in mitigating both attacks.
