This paper analyzes the blackhole attack which is one of the possible attacks in ad hoc
networks. In a blackhole attack, a malicious node impersonates a destination node by …

The paper presents a general approach for detecting black-hole attacks in mobile ad hoc
networks, which, due to their mobility and being broadcast in nature, are particularly …

Black and gray hole attack is one kind of routing disturbing attacks and can bring great
damage to the network. As a result, an efficient algorithm to detect black and gray attack is …

Mobile ad-hoc networks are prone to a number of security threats. The fact that mobile ad-
hoc networks lack fixed infrastructure and use wireless link for communication makes them …

Protecting the network layer from malicious attacks is an important and challenging security
issue in mobile ad hoc networks (MANETs). In this paper, a security mechanism is proposed …

Mobile ad hoc networks (MANETs) are usually formed without any major infrastructure. As a
result, they are relatively vulnerable to malicious network attacks, and therefore, security is a …

Security is an essential component for mobile ad hoc network (MANET). In order to provide
security against attacker, researchers are working specifically on the security challenges in …

A black hole attack in ad hoc network refers to an attack by malicious nodes, which forcibly
acquires the route from a source to destination by falsely advertising shortest hop count to …

Due to wireless communication, dynamic topology, limited resources and lack of centralized
administration, MANETs are vulnerable to various types of DoS attacks on network layer. In …

Security is an essential requirement in mobile ad hoc networks to provide protected
communication between mobile nodes. Due to unique characteristics of MANETS, it creates …
