Intrusion detection plays an important role in the area of security in WSN. Detection of any type of intruder is essential in case of WSN. WSN consumes a lot of energy to detect an intruder. Therefore we derive an algorithm for energy efficient external and internal intrusion detection. We also analyse the probability of detecting the intruder for heterogeneous WSN. This paper considers single sensing...
In recent year with the widespread use of mobile device, Mobile Ad hoc networks (MANETs) technology has been attracted attention day by day. Due to MANETs don't need the infrastructure, it can deploy fast and conveniently in any environment. Because of its easy deployment features, in addition to used in personal area networks, home area networks and so on. Specially, MANETs suit for military operations...
The node capture attack on wireless sensor networks (WSNs) can be broken into three stages: node capture, node redeployment, and insider attacks. Existing detection techniques of the attack are mostly implemented in the second stage. Recent discovery proved the feasibility of quick and effective detection in the first stage. We propose a hello message based first stage detection scheme, which is faster,...
In a mobile ad-hoc network, nodes cannot rely on any fixed infrastructure for routing purposes. Rather, they have to cooperate to achieve this objective. However, performing network functions consumes energy and other resources. Therefore, some network nodes may decide against cooperating with others; selfish nodes. Also security issues are more paramount in such networks even more so than in wired...
The proposed model in this paper is the intrusion detection techniques for mobile ad-hoc networks, which use collaborative efforts of nodes in a neighborhood to detect a malicious node in that neighborhood. The technique is designed for detection of malicious nodes in a neighborhood of nodes in which each pair of nodes in the neighborhood are within radio range of each other. Such a neighborhood of...
Testing of applications for tactical MANETs poses a special technical challenge due to the difficulty of conducting experiments in an ad hoc network environment at a scale larger than a few nodes. One approach is to conduct experiments in Virtual Ad hoc Network (VAN) testbeds that can imitate a tactical MANET to a high level of fidelity. For applications, this is achieved by executing unmodified software...
Even though Intrusion Detection Systems (IDS) are in wide-spread use, the question of how to efficiently initiate responses to detected attacks has been discussed far less often, especially in highly dynamic scenarios such as tactical MANETs. Despite being flexible and robust in their ability to self-organize, these MANETS are distinctly more susceptible to attacks than their wired counterparts. Especially...
The security of wireless sensor networks is an important field of research about WSNs, and has attracted a lot of attentions nowadays. Reputation based trust systems represent soft security mechanisms that complement traditional information security. Nowadays, the research of trust security mechanism based on reputation and has become a hot research issue in wireless networks. In this paper, we propose...
The inherent freedom in self-organized mobile ad-hoc networks (MANETs) introduces challenges for trust management; particularly when nodes do not have any prior knowledge of each other. Furthermore in MANETs, the nodes themselves should be responsible for their own security. We propose a novel approach for trust management in MANETs that is based on the nodes' own responsibility of building their...
Wireless sensor networks are specific adhoc networks. They are characterized by their limited computing power and energy constraints. This paper proposes a study of security in this kind of network. We show what are the specificities and vulnerabilities of wireless sensor networks. We present a list of attacks, which can be found in these particular networks, and how they use their vulnerabilities...

Vehicular ad hoc networks support a wide range of promising applications including vehicular sensing networks, which enable vehicles to cooperatively collect and transmit the aggregated traffic data for the purpose of traffic monitoring. The reported literatures mainly focus on how to achieve the data aggregation in dynamic vehicular environment while the security issue especially on the authenticity...
In this paper, a security architecture is designed based on the artificial immune system by using multi-agents in mobile ad hoc networks. There are two types of immunity-based agents: one is detection agent and the other is counterattack agent. Detection agents take charge of monitoring the nodes in the network, detecting the anomaly activities, and taking response to the invader, which may be viewed...
In mobile ad hoc networks the nodes are dynamically changing and they have a fully decentralized topology. Hence, security is hard to achieve due to the dynamic nature of the relationships between the participating nodes as well as the vulnerabilities and limitations of the wireless transmissions medium. We proposed a novel agent based framework to monitor, detect, and isolate misbehaving nodes in...
A malicious node in mobile ad hoc networks (MANETs) can falsify a route advertisement, overwhelming traffic without forwarding it, helps in forwarding corrupted data, and injecting of false or uncompleted information. Mapping immune system security mechanisms to networking security can powerfully contribute in securing MANETs, since both are sharing some similar features because of the distributability...
Mobile ad hoc network is a special peer-to-peer network with a wide range of application that has no infrastructure, multi-hop, self-organizing, dynamically reconfiguration and mobile. People are now paying more and more attention to the using of ad hoc network in the emergence area such as battlefield and disaster rescue. The research on its energy and security are one of the most important aspects...

Existing investigation schemes are not suitable to cope with attacks in wireless networks, especially in MANet. We propose in this paper a formal approach for digital investigation of security attacks in wireless networks. We provide a model for describing attack scenarios in wireless environment, and system and network evidences generated consequently. We develop an inference system that integrates...
Traditional routing protocols deployed to provide communication among mobile nodes in wireless ad hoc networks (MANET) assume a trust and collaborating environment inside the network. However, this assumption is not always true and a hostile or unprotected environment can seriously affect the protocol and network performance. In this work two kinds of approaches are applied to a well-known routing...
