Analysis of Behavioral Characteristics of Jammers to Detect Malicious Nodes in Mobile ADHOC Networks

Wireless ADHOC Networks are used to establish a wireless connection between two computing devices without the need for Wi-Fi access point or router. This network is decentralized and uses omnidirectional communication media, which makes it more vulnerable certain types of attacks compared wired networks. Jamming attacks, subset denial-of-service (DoS) involve malicious nodes that intentionally interfere with network, blocking legitimate communication. To address this issue, proposed method analyzes various characteristics nodes, such as packets sent, received, dropped, at each node. Using packet delivery ratio drop ratio, detects jamming from normal improving performance. The simulated in NS2 environment.
