Performance comparison of Intelligent Jamming in RF (Physical) Layer with WLAN Ethernet Router and WLAN Ethernet Bridge

The very nature of Radio Frequency (RF) technology makes Wireless LANs (WLANs) open to a variety of unique attacks. Most of these RF-related attacks begin as exploits of Layer 1 (Physical - PHY) & Layer 2 (Media Access Control - MAC) of the 802.11 specification, and then build into a wide array of more advanced assaults, including Denial of Service (DOS) attacks. In Intelligent Jamming the jammer jammed physical layer of WLAN by generating continuous high power noise in the vicinity of wireless receiver nodes. In this paper, we study the threats in an Intelligent jamming Comparison with WLAN Ethernet Router and WLAN Ethernet Bridge and the security goals to be achieved. We present and examine analytical simulation results for the throughput for different scenario performance, using the well-known network simulator OPNET 10.0 and OPNET Modeler 14.5 for WiMAX Performance. IEEE 802.11b has two different DCF modes: basic CSMA/CA and RTS/CTS. Intelligent jamming, which jams with the knowledge of the protocol, the jamming describe in our paper is based on the basis of Fake AP Jamming. When we have applied same concept in WiMAX system under the influence of jamming we have received same effect of router performance.
