ACO based AODV Method for Detection and Recovery of Misbehaving Nodes

Mobile ad-hoc networks (MANETs) can be described as a set of a huge variety of mobile nodes. MANET has the kind of applications such navy, disaster stuck regions and the characteristics of dynamic topology, no constant infrastructure, and many others. Nevertheless, there are a few protection issues and challenges in it. MANET is vulnerable to numerous attacks because of its open medium. As a result, there's need to examine in detail about the way to discover malicious or misbehaving node present inside the network. Ant algorithm is a set of rules this is most appropriate to be carried out in MANET environments than other algorithms. It can discover a most effective route, independent, decentralized, rapid adaptation, and multiple routes. Due to this motive, we use ant algorithm to enhance the overall performance of the proposed comfortable protocol. in this paper, Ant-primarily based Misbehavior node detection approach is carried out with ad-hoc On-demand Distance Vector (AODV) protocols and it figuring out the misbehavior node properly evaluate the parameters of packet delivery ratio, throughput and so on

Trust-based security for the OLSR routing protocol

International audienceThe trust is always present implicitly in the protocols based on cooperation, in particular, between the entities involved in routing operations in Ad hoc networks. Indeed, as the wireless range of such nodes is limited, the nodes mutually cooperate with their neighbors in order to extend the remote nodes and the entire network. In our work, we are interested by trust as security solution for OLSR protocol. This approach fits particularly with characteristics of ad hoc networks. Moreover, the explicit trust management allows entities to reason with and about trust, and to take decisions regarding other entities. In this paper, we detail the techniques and the contributions in trust-based security in OLSR. We present trust-based analysis of the OLSR protocol using trust specification language, and we show how trust-based reasoning can allow each node to evaluate the behavior of the other nodes. After the detection of misbehaving nodes, we propose solutions of prevention and countermeasures to resolve the situations of inconsistency, and counter the malicious nodes. We demonstrate the effectiveness of our solution taking different simulated attacks scenarios. Our approach brings few modifications and is still compatible with the bare OLSR

Administrator and Fidelity Based Secure Routing (AFSR) Protocol in MANET

The proliferation of mobile computing and communication devices are driving a revolutionary change in our information society. Among all the applications and services run by mobile devices, network connections and corresponding data services are without doubt the most demanded services by mobile users. A MANET is a continuously self-configuring, infrastructure-less network of mobile devices connected without wires, which makes it ideal for the present scenario. But, due to lack of any centralized infrastructure and access to trusted authorities, the security in MANET poses a huge threat. The prominent routing protocols we know are generally designed for environments where the nodes within a network are non-malicious. Due to the vulnerable nature of the mobile ad hoc network, there are numerous security threats that disturb its development. We propose a protocol for MANETs named “Administrator and Fidelity Based Secure Routing Protocol” (AFSR), which ensures secure routing through the network: by electing an Administrator node on the basis of Willingness and Fidelity, after which a node only communicates to that secure Admin node. This selection of secured admin nodes results in mitigation of various threats. We have evaluated our proposed protocol by simulating and comparing in GloMoSim

Survey on EAACK - A Secure Intrusion-Detection System for MANETs

The past few decade migration to wireless network from wired network has been a global trend. Wireless network made it possible in many applications to have mobility and scalability. Among all the modern wireless networks, Mobile Ad hoc NETwork (MANET) is one of the most important and unique applications. MANET is more popular now days. On the conflicting to traditional network architecture, MANET not has a fixed network infrastructure; every single node works as both a transmitter and a receiver. Nodes within same communication range are communicated directly with each other. Otherwise, they depend on their neighbors to relay messages. Because of the self-configuring ability of nodes in MANET made it popular among critical mission applications like military use or emergency recovery. Now days, security has become a very important service in Mobile Adhoc Network. As Compared with other networks, MANETs are more vulnerable to various types of attacks. This paper presents an overview of Secure Intrusion-Detection Systems for discovering malicious nodes and attacks on MANETs. Because of some special characteristics of MANETs, prevention mechanisms alone are not satisfied to manage the secure networks. In this, detection should be focused as another part before an attacker can damage the structure of the system. This paper gives an overall overview of IDS architecture for improving the security level of MANETs. For enhancing the security based on security attributes and then various algorithms like RSA and DSA
