A COUNTERMEASURE FOR FLOODING ATTACK IN MOBILE WiMAX NETWORKS
نویسندگان
چکیده
Worldwide Interoperability for Microwave Access (WiMAX) is a new communication technology that conduits the fissure between fixed and mobile access and offers the same Quality of Service (QoS) to both types of users. Generally, WiMAX is more vulnerable to the inside and outside attacks due to the absence of any clear line of defense. The Mobile Subscriber Stations (MSSs) selected to transfer the packets to the Base Station (BS) are vulnerable to Denial of Service (DoS) attacks like flooding. Recent research has discovered that DoS attacks can easily be launched by injecting malevolent management frames into the WiMAX network based on the Privacy and Key ManagementReSPonse (PKM-RSP) and Automatic Repeat ReQuest (ARQ)-Reset messages. In this paper, an algorithm is proposed to mitigate the flooding attacks and enhance the security level in the network.

A New Intrusion Detection System to deal with Black Hole Attacks in Mobile Ad Hoc Networks
By extending wireless networks and because of their different nature, some attacks appear in these networks which did not exist in wired networks. Security is a serious challenge for actual implementation in wireless networks. Due to lack of the fixed infrastructure and also because of security holes in routing protocols in mobile ad hoc networks, these networks are not protected against attack...

Mobile ad hoc networks are networks composed of wireless devices to create a network with the ability for self-organization. These networks are designed as a new generation of computer networks to satisfy some specific requirements and with features different from wired networks. These networks have no fixed communication infrastructure and for communication with other nodes the intermediate no...
متن کاملA Gateway-based Defense System for Distributed Denial-of-Service Attacks in High-Speed Networks
We describe a defense system to contain Distributed Denial-of-Service (DDoS) flooding attacks in highspeed networks. We aim at protecting TCP friendly traffic, which forms a large portion of Internet traffic. DDoS flooding attacks tend to establish large numbers of malicious traffic flows to congest network. These flows are marked as TCP flows, and use spoofed source identifiers to hide their i...
متن کاملA New Routing Attack in Mobile Ad Hoc Networks
Mobile ad hoc networks will often be deployed in environments where the nodes of the networks are unattended and have little or no physical protection against tampering. The nodes of mobile ad hoc networks are thus susceptible to compromise. The networks are particularly vulnerable to denial of service (DOS) attacks launched through compromised nodes or intruders. In this paper, we present a ne...
متن کاملA Survey of Solutions to Protect Against All Types of Attacks in Mobile Ad Hoc Networks
In recent years mobile networks have expanded dramatically, compared with other wireless networks. Routing protocols in these networks are designed with the assumption that there is no attacker node, so routing protocols are vulnerable to various attacks in these networks. In this paper, we review the network layer attacks and then we simulate the impact of black hole attack on ad hoc on demand...
