There are several routing protocols that have been proposed for the possible deployment of MANETs in many fields like military, government and commercial applications. While the routing aspects of MANETs are already well understood but the research activities about the security in MANETs are still at their beginning. This paper focuses on the performance investigation of reactive and proactive ...

Vehicular Ad hoc Network is one of the interesting and attractive topics in the recent years. It has a potential to achieve intelligent inter vehicle communication for the benefit of the vehicle user. The VANET has lot of challenges. These decentralized dynamic networks require a secure communication. These networks are vulnerable to various attacks. In this paper the security features of routi...

Delay Tolerance Network (DTN) is a network which is used for sparse networks where network connectivity is not possible between two nodes so for this number of intermediate nodes is used to transfer messages. These intermediate nodes may cause network so security in DTN is a very difficult task. In this paper blackhole attack and its various detection techniques are presented with literature re...

The wireless sensor networks are prone to various attacks; this is primarily due to the fact that these networks once deployed are left unattended. So any attacker with the intention of stealing the information from the network can compromise any node and gain access to the data being propagated in the network. Various attacks possible are black hole attack, wormhole attack, Sybil attack, clone...

A mobile ad-hoc network (MANET) is a collection of wireless mobile nodes that dynamically self-organize to form an arbitrary and temporary network. The mobile nodes can communicate with each other without any fixed infrastructure. MANET can be set up quickly to facilitate communication in a hostile environment such as battlefield or emergency situation. The various severe security threats are i...

: In mobile ad-hoc network (MANET), secure routing is a challenging issue due to its open nature, infrastructure less property and mobility of nodes. Many mobile ad-hoc network routing schemes have been proposed, but none of them have been designed with security as a goal. We propose security goals for routing in mobile ad-hoc networks, an approach significantly different from the existing ones...

Security is a key feature in Wireless Sensor Networks but they are prone to many kinds of attacks and one of them is Black Hole Attack. In a black hole attack all the packets are consecutively dropped which leads to the decrease in the efficiency of the network and unnecessary wastage of battery life. In this paper, we propose an exponential trust based mechanism to detect the malicious node. I...

Mobile ad hoc network (MANET) is a collection of mobile nodes which are self configuring and connected by wireless links automatically as per the defined routing protocol. A mobile network is one of the most busiest and the public network, because of this the network suffers from the problems of different kind of attacks. One of such attack is Black hole attack in which malicious node falsely c...
