ZSBT: A Novel Algorithm for Tracing DoS Attackers in MANETs

ZSBT: A Novel Algorithm for Tracing DoS Attackers in MANETs

Denial of service (DoS) attack is a major class of security threats today. They consume resources of remote hosts or network and make them deny or degrade services for legitimate users. Compared with traditional Internet, the resources, such as bandwidth, memory, and battery power, of each node are more limited in mobile ad hoc networks (MANETs). Therefore, nodes in MANETs are more vulnerable t...

A Probabilistic Framework for Localization of Attackers in MANETs

A Probabilistic Framework for Distributed Localization of Attackers in MANETs

Mobile Ad-hoc Networks (MANETs) are frequently exposed to a wide range of cyber threats due to their unique characteristics. The lack of a centralized monitoring and management entity and the dynamic nature of their topology pose new and interesting challenges for the design of security mechanisms for MANETs. While conventional methods primarily focus on detecting attacks, in this work we focus...

Tracing Anonymous Mobile Attackers in Wireless Network

In a flooding-based distributed denial-of-service (DDoS) attack, an adversary attempts to exhaust a target’s computing resource. To detect DDoS attacks in a network environment, IP traceback methods are deployed to determine the origin of attack packets. With the increase in bandwidth of wireless networks, attackers may choose this medium from which to launch attacks. However, tracing the attac...

DoS Attacks in MANETs: Detection and Countermeasures

With the widespread use of lightweight devices like laptops, PDAs, wireless telephones and sensors, the importance of wireless computing and particularly mobile ad hoc networking have come to the fore. Continued reduction in cost has resulted in diverse fields where deployment of such networks is being conceived. In mobile networks, there are some applications, which cannot rely on the presence...
