Dynamic variation of network topology in mobile ad hoc networks (MANET) forces network
nodes to work together and rely on each other for routing. Considering the lack of a central …

The wireless arena has been experiencing exponential growth in nowadays. Wireless
devices are now playing an everincreasingly important role in our lives. an ad hoc network …

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 Network (MANET) has distributed mobile wireless nodes, which do not have
pre-determine topology and pre-existing infrastructure mobile nodes that can arbitrarily …

Security plays a vital role to provide protected data transmission in Mobile Ad-hoc Networks
(MANETs). Mobile nodes communicate in multi-hop way via routing protocols that work in …

Wireless shared medium, randomly moving nodes and multi-hop architecture make mobile
ad hoc networks vulnerable to various network layer threats. Grayhole attack is such a …

Mobile Ad-hoc network is characterized as a network of the self-configuring type that
comprises several mobile nodes and can be set up easily without needing any kind of …

The most critical issue related to the mobile ad hoc networks is the security. Due to various
characteristics, MANET is likely to be exposed to the Grayhole attack. This type of attack …

Mobile ad-hoc networks (MANETs) are composed of autonomous nodes that are self-
managed, dynamically deployed without any pre-existing infrastructure. Gray hole attacks …

As the mobile ad hoc networks infrastructure has no centralized points of connections, the
traffic from a source to a destination passes through number of intermediate nodes. When …
