In a multi-hop hop mobile ad hoc network (MANET), mobile nodes cooperate with each other without using any infrastructure such as access points or base stations. The nodes’ mobility and fundamentally limited capacity of the wireless medium, together with wireless transmission effects such as attenuation, multi-path propagation, and interference combine to pose significant challenges for security in MANETs. Traditionally, cryptographic mechanisms such as authentication and encryption are not capable of handling some kinds of attacks such as packet dropping by malicious nodes. In this paper, we propose a mechanism for detection of malicious packet dropping attack in MANET. The mechanism depends on a trust module based on the ‘reputation’ of different nodes in the network. Every node computes the reputation of its neighbors by directly monitoring their behaviors. The reputation information is gathered, stored, and exchanged between the nodes and computed under different scenarios. We have validated the scheme with some simulation work, which shows the feasibility and efficiency of performance of the protocol.

In a multi-hop mobile ad hoc network (MANET) mobile nodes communicate with each other forming a cooperative radio network. Security remains a major challenge for these networks due to their features of open medium, dynamically changing topologies, reliance on cooperative algorithms, absence of centralized monitoring points, and lack of any clear lines of defense. Most of the currently existing security algorithms designed for these networks are insecure, in efficient, and have low detection accuracy for nodes’ misbehaviour. In this paper, a new approach has been proposed to bring out the complementary relationship between key distribution and misbehaviour detection for developing an integrated security solution for MANETs. The redundancy of routing information in ad hoc networks is utilized to develop a highly reliable protocol that works even in presence of transient network partitioning and Byzantine failure of nodes. The proposed mechanism is fully co-operative, and thus it is more robust as the vulnerabilities of the election algorithms used for choosing the subset of nodes for cooperation are absent. Simulation results show the effectiveness of the proposed protocol.
Hybrid Trust Based Reputation Mechanism for Discovering Malevolent Node in MANET
Computer Systems Science and Engineering
A self-contained connection of wireless links that functions without any infrastructure is known as Mobile Ad Hoc Network (MANET). A MANET's nodes could engage actively and dynamically with one another. However, MAN-ETs, from the other side, are exposed to severe potential threats that are difficult to counter with present security methods. As a result, several safe communication protocols designed to enhance the secure interaction among MANET nodes. In this research, we offer a reputed optimal routing value among network nodes, secure computations, and misbehavior detection predicated on node's trust levels with a Hybrid Trust based Reputation Mechanism (HTRM). In addition, the study designs a robust Public Key Infrastructure (PKI) system using the suggested trust evaluation method in terms of "key" generation, which is a crucial component of a PKI cryptosystem. We also concentrate on the solid node authenticating process that relies on pre-authentication. To ensure edge-to-edge security, we assess safe, trustworthy routes to secure computations and authenticate mobile nodes, incorporating uncertainty into the trust management solution. When compared to other protocols, our recommended approach performs better. Finally, we use simulations data and performance evaluation metrics to verify our suggested approach's validity Our approach outperformed the competing systems in terms of overall end-to-end delay, packet delivery ratio, performance, power consumption, and key-computing time by 3.47%, 3.152%, 2.169%, and 3.527%, 3.762%, significantly.
Trust Based Solution To Packet Drop Attack In The MANET
2015
The Mobile Ad-hoc Network (MANET) is self-organizing communication network of the mobile node. The MANET does not have any prior structure of communication. The mobile ad hoc network creates a network with the help of intermediate nodes. The network is open network environment so that intermediate node can participate in the communication. The MANET has a serious security problem, because of the public nature of the network. The malicious node can quickly enter into the system. The security issue mainly contains a denial of service attacks like packet drop attack, black hole attack, gray hole attack, etc. The system based on receive and reply messages. It helps to generate mutual trust between neighboring nodes. This proposed algorithm works on trust based on removal of packet drop attack in MANET. This proposed algorithm implemented in Network Simulator 2.35. The concept of trust and energy is used for detection malicious node present the network. The power of node is used to diffe...
This research effort examines the theory, application, and results for a Reputation-based Internet Protocol Security (RIPSec) framework that provides security for an ad-hoc network operating in a hostile environment. In RIPSec, protection from external threats is provided in the form of encrypted communication links and encryption-wrapped nodes while internal threats are mitigated by behavior grading that assigns reputations to nodes based on their demonstrated participation in the routing process. Network availability is provided by behavior grading and round-robin multipath routing. If a node behaves faithfully, it earns a positive reputation over time. If a node misbehaves, it earns a negative reputation. Each member of the MANET has its own unique and subjective set of Reputation Indexes (RI) that enumerates the perceived reputation of the other MANET nodes. Nodes that desire to send data will eliminate relay nodes they perceive to have a negative reputation during the formulati...
Mobile ad-hoc network (MANET) is one of the most propitious area in research and development of wireless network. Popularity of mobile device and wireless networks significantly increased over the past years. MANET has no centralized control to handle the network, so this may cause to fails the functioning. This characteristic force a component node to be careful when communicating with other nodes as the behavior of nodes change with time and environmental conditions, so the security issues may arise like impersonation etc. Therefore behavior of node should consider improving the security of MANET. This is mostly important in big network where heterogeneous nodes are the parts of network for e.g. tactical and social network. The behavior of node is shown in the form of numerical value called as trust. Trust is calculated and aggregated and shared among network. Every node's generated trust is on the basis of serious study, others node opinion, and previous interaction and their own policy. In this report, we have analyzed different proposed trust based mechanism and trust evaluation based security solution. These techniques are proposed to make trust security solutions more effective.
New trust based security method for mobile ad-hoc networks
International Journal of Computer Science and …, 2010
Secure routing is the milestone in mobile ad hoc networks .Ad hoc networks are widely used in military and other scientific areas with nodes which can move arbitrarily and connect to any nodes at will, it is impossible for Ad hoc network to own a fixed infrastructure. It also has a certain number of characteristics which make the security difficult. Routing is always the most significant part for any networks. We design a trust based packet forwarding scheme for detecting and isolating the malicious nodes using the routing layer information. This paper gives an overview about trust in MANETs and current research in routing on the basis of trust. It uses trust values to favor packet forwarding by maintaining a trust counter for each node. A node will be punished or rewarded by decreasing or increasing the trust counter. If the trust counter value falls below a trust threshold, the corresponding intermediate node is marked as malicious. .
Reputation methods for routing security for mobile ad hoc networks
SympoTIC'03. Joint 1st Workshop on Mobile Future and Symposium on Trends in Communications, 2003
Mobile ad hoc networks have inherently very different properties to conventional networks. These new characteristics present major security vulnerabilities; in particular, one side effect of the unique way in which routing protocols operate in ad hoc networks is that many new threats arise. Selfish nodes are those which do not perform certain operations that the protocol specifies that they should, through a wish to conserve power. Malicious nodes may deliberately disrupt the network using a variety of attacks. This paper discusses reputation mechanisms which have been suggested as a means to mitigate the detrimental effect of selfish and malicious nodes. This paper reveals reasons why complex reputation systems may be too inefficient to use in a mobile ad hoc network, where resources are limited. However, suggestions are also made to show how a simple reputation system might be used to enhance the robustness of ad hoc networks.
Mitigating Various Attacks in Mobile Ad-hoc Networks Using Trust Based Approach
A Mobile ad hoc network (MANET) is self-organizing, decentralized and infrastructure-less wireless network. The successful transmission of the data packet depends on the complete cooperation of each node in the network. These types of network don’t have permanent base station, so each node in the network acts as a router. Due to openness, decentralized, selforganizing nature of MANET, it is vulnerable to various attacks. So security is the main concern in MANET. In this project, we have considered 2 attacks; Vampire attack and DDoS attacks. Vampire attack drains the energy of the nodes. DDoS attack exhausts the resources available to a network, such that the node cannot provide any services. Here, we discuss methods 2 methods as a solution to our problem; one is to prevent the attack from happening and other to detect and recover from the attacks.
