Internet of Things (IoTs) is a new concept in computer science that connects the objects with limited resources to unreliable internet through different technologies. The fundamental components of IoT (e.g., the wireless sensor networks and the internet) have an unsecured foundation that leads to different vulnerabilities such as vulnerability against a blackhole attack. In a blackhole attack, the attacker fakes itself as the shortest path to the destination, which is a node here. This causes the routing packets to not reach the destination. In this study, we offer a novel intelligent agent-based strategy using the hello packet table (NIASHPT) to deal with these problems by discovering the blackhole attacks. The proposed NIASHPT method provides an intrusion detection system scheme to defend against blackhole attacks and reduce or eliminate such attacks. This method consists of three phases: In the first phase, each node listens to its adjacent nodes and then applies a pre-routing process. In the stages of adjacent node listening and pre-routing, we attempt to find the blackhole attacks. In the second phase of the proposed method, the malicious nodes are detected and separated from the IoT network to avoid emerging attacks along the route from the source to the destination. In the third phase, the selected route from the source to the destination is checked. The method is evaluated here via extensive simulations carried out in the NS-3 environment. The experimental results of four scenarios demonstrated that the NIASHPT method can achieve a false positive rate of 19.453%, a false negative rate of 22.19%, a detection rate of 80.5%, a PDR of 89.56%, and a packet loss rate of 10.04% in the case of launching a blackhole attack.

NIASHPT：一种新的基于智能代理的策略，使用 hello 数据包表 (HPT) 功能实现信任物联网

物联网 (IoT) 是计算机科学中的一个新概念，它通过不同的技术将资源有限的对象连接到不可靠的互联网。物联网的基本组件（例如，无线传感器网络和互联网）具有不安全的基础，这会导致不同的漏洞，例如针对黑洞攻击的漏洞。在黑洞攻击中，攻击者将自己伪装成到达目的地的最短路径，也就是这里的一个节点。这会导致路由数据包无法到达目的地。在这项研究中，我们提供了一种新的基于智能代理的策略，使用 hello 数据包表（NIASHPT）通过发现黑洞攻击来处理这些问题。所提出的 NIASHPT 方法提供了一种入侵检测系统方案来防御黑洞攻击并减少或消除此类攻击。该方法包括三个阶段：在第一阶段，每个节点侦听其相邻节点，然后应用预路由过程。在相邻节点侦听和预路由阶段，我们试图找到黑洞攻击。在所提出方法的第二阶段，检测恶意节点并将其与物联网网络分离，以避免沿从源到目的地的路线出现攻击。在第三阶段，检查从源到目的地的选定路由。此处通过在 NS-3 环境中进行的大量模拟来评估该方法。
