Analysis of DoS attacks at MAC Layer in mobile adhoc networks

Abstract

Wireless network security has received tremendous attention due to the vulnerabilities exposed in the open communication medium. The most common wireless Medium Access Control (MAC) protocol is IEEE 802.11, which assumes all the nodes in the network are cooperative. However, nodes may purposefully misbehave in order to disrupt network performance, obtain extra bandwidth and conserve resources. These MAC layer misbehaviours can lead to Denial of Service (DoS) attacks which can disrupt the network operation. There is a lack of comprehensive analysis of MAC layer misbehaviour driven DoS attacks for the IEEE 802.11 protocol in MANETs. This research studied possible MAC layer DoS attack strategies that are driven by the MAC layer malicious/selfish nodes on IEEE 802.11 protocol. Such DoS attacks could caused by malicious and selfish nodes by violating their backoff timers associated with the MAC protocol. Therefore, these attacks are experimentally analysed and evaluated the impact on the network performance and stability in MANETs. The simulation results show that introducing DoS attacks at MAC layer could significantly affect the network throughput and data packet collision rate. This paper concludes that DoS attacks with selfish/malicious intend can obtain at least 50% larger throughput by denying wellbehaved nodes to obtain deserved throughput, also DoS attacks with the intend of complete destruction which allow only less than 5% throughput for well-behaved nodes which eventually led to shut-down of the network.Index Terms-Wireless Network Security, IEEE 802.11, Medium Access Control, Denial of Service, MAC Layer Misbehaviours 978-1-4799-5344-8/15/$31.00 ©2015 IEEE

A Novel Approach to detect Denial Of Service Attack in MANET

“…The simulation results demonstrate that presenting DOS attacks at MAC layer would gigantically influence the system throughput and data packet collision rate [7].…”

“…Chaminda Alocious [2015]et al This paper reasons that DOS attacks with selfish/malicious, mean can get no less than 50% better throughput with the aid of denying well-behaved nodes to receive deserved throughput, also DOS attacks with the intend of complete destruction which permit simplest less than 5% throughput for well-behaved nodes which at last prompted close down of the network. The simulation results demonstrate that presenting DOS attacks at MAC layer would gigantically influence the system throughput and data packet collision rate [7].…”

SRDP: Secure Route Diversion Policy for Resisting Illegitimate Request in MANET

“…The Work of Alocious et al [4] have conducted an analytical study of Misbehaviors of Mac layer under DoS attack with IEEE 802.11 protocol in the MANETs Surroundings. The outcome of the study display that the DoS attack on MAC layer degrades the performance of network in terms of throughput and higher data packet loss rate.…”

Resilient misbehaviour detection MAC protocol (MD-MAC) for distributed wireless networks

“…There has been many research to analyse MAC layer misbehaviours in Wireless Networks. The research in [3] has conducted an analysis of MAC layer DoS attacks in MANETs. The authors have analysed both sender and receiver misbe-haviours and concludes that misbehaving nodes can obtain a larger throughput which significantly affect the network performance, even capable of completely freeze the network at higher rate attacks.…”
