An Experimental Evaluation of DoS Attack and Its Impact on Throughput of IEEE 802.11 Wireless Networks

چکیده
In recent years, wireless LAN (WLAN) has gained popularity in a variety of locations. This has lead to development of high level security protocols for WLAN. The newest protocol IEEE 802.11i ratified to provide strong data encryption but it can not prevent Denial of Service (DoS) attacks on WLAN. This paper in a testbed, conducts an experimental framework to implement and quantify common types of DoS attacks against WLAN throughput. The results of implementation of our experiments shows that how easily DoS attacks can be performed on WLAN which causes to reduce throughput of communication considerably to make inaccessible wireless connection for its authorized members.

Many performance evaluations for IEEE 802.11distributed coordination function (DCF) have been previouslyreported in the literature. Some of them have clearly indicatedthat 802.11 MAC protocol has poor performance in multi-hopwireless ad hoc networks due to exposed and hidden nodeproblems. Although RTS/CTS transmission scheme mitigatesthese phenomena, it has not been successful in thoroughlyomit...

متن کامل802.11 Disassociation DoS attack Simulation Using Verilog*
A number of Denial of Service (DoS) attacks in IEEE 802.11 are due to unauthenticated/ unencrypted management and control frames. Current IEEE 802.11 simulators deal with Physical and MAC layers and do not include the exchange of management and control frames, thus making it difficult to simulate an attack (DoS) and its possible solution. A basic IEEE 802.11 network simulator using Verilog is p...
متن کاملAn Energy Efficient Clustering Method using Bat Algorithm and Mobile Sink in Wireless Sensor Networks
Wireless sensor networks (WSNs) consist of sensor nodes with limited energy. Energy efficiency is an important issue in WSNs as the sensor nodes are deployed in rugged and non-care areas and consume a lot of energy to send data to the central station or sink if they want to communicate directly with the sink. Recently, the IEEE 802.15.4 protocol is employed as a low-power, low-cost, and low rat...

Despite current 802.11i security protocol, wireless networks are vulnerable to Denial of Service (DoS) attacks. Sending a continuous stream of forgery control frames by an attacker can easily flood wireless channel so that the network cannot be available for its associated users. These attacks are possible because wireless control frames do not carry any cryptographic mechanism to detect and di...
