Detection and Prevention of MAC Layer Misbehavior for Ad
Selfish behavior at the MAC layer can have devastating side effects on the performance of wireless networks, similar to the effects of DoS attacks. In this paper we focus on the prevention and detection of the manipulation of the backoff mechanism by selfish nodes in 802.11. We first propose an algorithm to ensure honest backoffs when at least one, either the receiver or the sender is honest. T...
متن کاملDetection and Handling of MAC Layer Misbehavior in Wireless Networks
Selfish hosts in wireless networks that fail to adhere to the MAC protocol may obtain an unfair share of the channel bandwidth. We present modifications to the IEEE 802.11 backoff mechanism to simplify detection of such selfish hosts. We also present a correction scheme for penalizing greedy misbehavior which attempts to restrict the misbehaving nodes to a fair share of the channel bandwidth. S...
متن کاملDetection and Prevention of MAC Layer Misbehavior for Ad Hoc Networks
It is known that 802.11 is not resilient to selfish behavior and denial of service (DoS) attacks targeting the MAC layer. In this study, we assess the performance of the CSMA/CA scheme and investigate its efficiency with regard to security and information assurance in mobile ad hoc wireless networks. We investigate several variants of selfish node behaviors that abuse the random choice of Conte...
متن کاملMultivariate Control Chart for the Detection of MAC Layer Misbehavior in Mobile ad Hoc Networks
The share nature of the transmission channel in IEEE 802.11 makes the network vulnerable to several attacks like the MAC layer misbehavior which can be similar to denial of service attack. In this way cheating node by choosing smaller backoff timer attempts to increase its resources at the expense to other stations which respect the protocol. In this paper, we suggest a novel detection scheme o...
متن کاملDiagnosing and Penalizing MAC Layer Misbehavior in Wireless Networks
Wireless Medium Access Control (MAC) protocols such as IEEE 802.11 use distributed contention resolution mechanisms for sharing the wireless channel. In this environment, selfish hosts that fail to adhere to the MAC protocol may obtain an unfair share of the channel bandwidth. For example, IEEE 802.11 requires nodes competing for access to the channel to wait for a “backoff” interval, randomly ...
