Mobile ad hoc networks are expected to be widely used in the near future. However, they are susceptible to various security threats because of their inherent characteristics. Malicious flooding attacks are one of the fatal attacks on mobile ad hoc networks. These attacks can severely clog an entire network, as a result of clogging the victim node. If collaborative multiple attacks are conducted...

Mobile Ad hoc Networks (MANET) have been highly vulnerable to attacks due to the dynamic nature of its network infrastructure. Among these attacks, routing attacks have received considerable attention since it could cause the most devastating damage to MANET. Even though there exist several intrusion response techniques to mitigate such critical attacks, existing solutions typically attempt to ...

-The growing popularity of the 802.11-based Wireless LAN (WLAN) also increases its risk of security attacks. The new WLAN security standard, 802.11i, addresses most issues on user authentication and data encryption; however, it does not protect WLANs against Denial of Service (DoS) attacks. This paper presents a solution to detect and resolve authentication request flooding (AuthRF) and associa...

Mobile Adhoc Networks (MANET) are special because of their self configuring and self maintenance capabilities. The highly dynamic network topology and the shared wireless medium are the main attractions and at the same time the main challenges of the MANET. These characters make MANET vulnerable to various attacks. There are several attacks on each layer of the protocol stack. Providing the sec...

Most of the network management part, especially a network security needs effective visualization methods for flooding connections. Because many web systems using huge users are suffering from huge normal connections with flooding attacks. Also, most of the connection cases have to be monitored for intrusion detection including any kinds of abnormal connection cases. Therefore, in this paper we ...

3 Abstract TCP-based flooding attacks are a common form of Distributed Denial-of-Service 4 (DDoS) attacks which abuse network resources and can bring about serious threats to the Internet. 5 Incorporating IP spoofing makes it even more difficult to defend against such attacks. Among 6 different IP spoofing techniques, which include random spoofing, subnet spoofing and fixed 7 spoofing, subnet s...

There are various overlay structures that provide efficient and scalable solutions for point and range query in a peer-topeer network. Overlay structure based on m-Binary Search Tree (BST) is one such popular technique. It deals with the division of the tree into different key intervals and then assigning the key intervals to a BST. The popularity of the BST makes this overlay structure vulnera...

Distributed denial-of-service (DDoS) attacks cause havoc by exploiting threats to Internet services. In this paper, we propose E-LDAT, a lightweight extended-entropy metric-based system for both DDoS flooding attack detection and IP (Internet Protocol) traceback. It aims to identify DDoS attacks effectively by measuring the metric difference between legitimate traffic and attack traffic. IP tra...

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 th...
