Mobile Ad hoc NETworks (MANET) are networks without infrastructure. The communication range among nodes is limited, where several hops are needed to transmit a packet from the source to the destination. These networks have a constantly changing topology due to its mobile nodes and their arbitrary connections, which make it vulnerable for different attacks. One of the most important attacks in MANET is the black hole attack which degrades the performance of the network by removing all the packets passing through it. There are several techniques for detecting black hole attacks in the ad hoc on demand vector protocol. In this paper, a new approach based on AACK is proposed. The proposed system is to detect the single and multiple black hole attacks by intrusion detection system with SPlitted AACK technique. The system is robust enough to detect all black hole attacks by using an iterative split of the main path until the detection of the malicious nodes. Network simulator 2 is used for simulation. We tested our system on different networks with different network sizes and different numbers of attacks, and we compared our results with some existing intrusion detection system techniques.

移动自组织NETworks（MANET）是没有基础结构的网络。节点之间的通信范围是有限的，需要几跳才能将数据包从源传输到目的地。这些网络由于其移动节点及其任意连接而具有不断变化的拓扑，这使其很容易受到不同的攻击。MANET中最重要的攻击之一是黑洞攻击，它会通过删除通过它的所有数据包来降低网络的性能。有几种用于检测即需即用矢量协议中的黑洞攻击的技术。本文提出了一种基于AACK的新方法。所提出的系统是通过采用SPlitted AACK技术的入侵检测系统来检测单个和多个黑洞攻击。该系统足够健壮，可以通过使用主路径的迭代拆分直到检测到恶意节点来检测所有黑洞攻击。网络模拟器2用于模拟。我们在具有不同网络规模和攻击次数的不同网络上测试了我们的系统，并将我们的结果与一些现有的入侵检测系统技术进行了比较。
