Abstract A distributed wireless network of mobile nodes is a mobile ad-hoc network (MANET). To exchange the information between nodes each node receives and forwards the data packets. Appropriate communication depends on cooperation between the nodes. But some nodes become malicious and misbehave during the communication. Therefore, MANET is vulnerable from those malicious nodes. The black hole node is treated as a malevolent node in MANET. Thus, the malicious node manipulates the source node’s false routing information and hence, drops every data packets without routing them to the destination point. The protection from the black hole attack, we have proposed a prominent prevention technique depend on the dynamic threshold, hop count and MAC address. In the proposed novel technique, it is verified by the legitimate device that the route reply packet (RREP) is either sent by the genuine or malicious node. In RREP packets, the node is suspicious. If the target sequence number is determined to be greater than the dynamic threshold of the corresponding node. Furthermore, the node is declared as the malicious node, when the hop count of the suspicious node one and MAC address flag is “DOWN”. Comparatively the proposed technique not only provides better in detection rate but also provide overall better performance in other metrics. A lightweight novel technique that detects the malicious node attack using MAC address and threshold value. the-art face recognition techniques.
