Network Analysis of ICMP Ping Flood DoS Attack in WiMAX and Wireless LAN

Sharing of data over the wireless network is an important activity in today's world. A malicious user may try blocking a service or intercept data. Such attacks on network are termed as denial-of-service attack. Due to the broadcast nature of wireless communication, exploitation of this kind of attack is even easier. That is why, security is a very critical issue in e-business. It is often impossible to measure its effectiveness in real life because of the network administrators' fears or prejudice. But before measuring its effectiveness and developing mitigation methods, it is important to understand the how such attacks actually works and we should have full knowledge about their characteristics and their impacts. In this paper, we present our approach to simulate the ICMP Ping Flood attack in WiMax and wireless LAN and to analyze the effects of this attack on wireless networks using OPNET Modeler.
