The Internet of things (IoT) is made up of huge sets of networked low-power devices. Regardless of the application specificities, those devices are generally tasked to provide highly important services that can be reached out through the internet. Communications with IoT networks cannot be achieved without the support of efficient underlying routing schemes. However, the constraints related to scarce resources, as well as the wireless and lossy nature of IoT networks may tremendously affect the communications reliability. Consequently, routing efficiency could be affected. Moreover, the exposure to internal and external cyber-attacks, especially those that threaten data and service availability, complicates even further routing and security missions in such a constrained context. In this paper, we propose an efficient solution that enhances both the communications reliability and security in the heterogeneous IoT-enabled low power and lossy networks. The solution relies on three variants of adaptive and secure multipath routing for IPv6 routing protocol for low-power and lossy networks (RPL). To the best of our knowledge, this is the first solution that deals with multipath routing security issue for RPL protocol, in IoT contexts. The proposed solution is evaluated with Cooja simulator of Contiki OS. The assessment results show obviously the effectiveness of the proposed solution for improved communication reliability and security, at low costs.

物联网（IoT）由大量联网的低功耗设备组成。无论应用程序的特殊性如何，这些设备通常负责提供可以通过Internet进行访问的非常重要的服务。没有有效的基础路由方案的支持，就无法实现与物联网网络的通信。但是，与稀缺资源相关的约束以及物联网网络的无线和有损特性可能会极大地影响通信可靠性。因此，路由效率可能会受到影响。此外，内部和外部网络攻击的暴露，尤其是那些威胁数据和服务可用性的网络攻击，在这种受限的情况下使进一步的路由选择和安全任务变得更加复杂。在本文中，我们提出了一种有效的解决方案，可增强异构IoT支持的低功耗和有损网络中的通信可靠性和安全性。该解决方案依靠适用于低功耗和有损网络（RPL）的IPv6路由协议的自适应和安全多路径路由的三种变体。据我们所知，这是第一个在物联网环境中处理RPL协议的多路径路由安全问题的解决方案。建议的解决方案使用Contiki OS的Cooja模拟器进行评估。评估结果显然表明，所提出的解决方案以低成本提高了通信可靠性和安全性的有效性。该解决方案依靠适用于低功耗和有损网络（RPL）的IPv6路由协议的自适应和安全多路径路由的三种变体。据我们所知，这是第一个在物联网环境中处理RPL协议的多路径路由安全问题的解决方案。建议的解决方案使用Contiki OS的Cooja模拟器进行评估。评估结果显然表明，所提出的解决方案以低成本提高了通信可靠性和安全性的有效性。该解决方案依靠适用于低功耗和有损网络（RPL）的IPv6路由协议的自适应和安全多路径路由的三种变体。据我们所知，这是第一个在物联网环境中处理RPL协议的多路径路由安全问题的解决方案。建议的解决方案使用Contiki OS的Cooja模拟器进行评估。评估结果显然表明，所提出的解决方案以低成本提高了通信可靠性和安全性的有效性。
