Design an Improved Trust-based Quality of Service AwareRouting in Cognitive Mobile Ad-Hoc Network

Mobile ad hoc networks (MANETs) are wireless networks that can be configured at will. It has no infrastructure and centralized control, so it is only suitable for provisional communications. In a dynamically topological and resource-constrained network, ensuring QoS and security is challenging. MANETs are dynamic networks, so navigating them can be challenging and more susceptible to attacks. MANET requires significant memory, speed, and transmission bandwidth for conventional security measures like cryptographic techniques. Consequently, these methods are unsuitable for identifying malicious behaviour or self-centered nodes. Nodes that are malicious, selfish, or malfunctioning can be identified based on the trust method, which calculates how much trust exists between them. A trust-based QOS-aware routing protocol is proposed in this paper to calculate trust in MANET (I-TQAR). The tree important performance metrics are considered for result validation such as delay, throughput and packet delivery ratio (PDR). I-TQAR offers significantly improved performance in all areas compared to the existing TQR and TQOR protocols.

Reliable and Hybridized Trust Based Algorithm to Thwart Blackhole Attacks in MANETs using Network Preponderant Determinants

<p>This Mobile adhoc networks is a perpetual and autogenous organization without framework, and the mobile nodes are coupled cordlessly. Owing to the deficiency of framework assistance, reliable data distribution is a demanding process in mobile adhoc networks and this mobile adhoc network is unguarded to many categories of attacks. A black hole attack in Mobile Adhoc networks cites to an attack by the malevolent node which strongly get hold of the path from sender to the receiver, by means of perversion of subsequence word. With regard to diminish the menace from the malevolent node, the authors encompass the notion of trust in mobile adhoc networks. In this paper, we cope with a packet dropping misconduct named Black hole Attack and we propounded a new hybrid trust based secured algorithm hinged on four new parameters to scrutinize, whether the transitional nodes are transmitting the packets correctly to the adjacent nodes. This paper presents a new hybrid trust based concept to pinpoint the malevolent node hinged on the computation of trust value. Using ns2 simulator, we analyse the performance of our proposed method and proved the detection efficiency. The investigated results shows that our proposed work can precisely diagnose the malevolent nodes and assure a good packet delivery ratio and network throughput.</p>

BHQRSM: Binary Hex Quadratic Residue Security Model to Enhance the Trust in MANETs

Mobile adhoc network (MANET) possesses various security challenges mainly due to its varying network topology. As central coordination is not possible in MANETs, sharing of keys between nodes is a difficult task. In this paper, we present a Binary Hex Quadratic Residue Security Model that does not require any kind of key distribution between the nodes in MANETs. We use a stream of equal weighted hex codes of decimal numbers and Ex-OR operations to generate a security vector which facilitates matching of code words and also determine the active and malicious nodes in the network. Our approach also saves energy as it requires less computational analysis when compared to existing approaches. We validate our approach through simulations results.

Enhancing trust in mobile ad-hoc network using trust and dynamic with energy efficient multipath routing protocol

Mobile ad-hoc network is one of the most effective self-configuring and infrastructure less based communication networks. During the communication process, trust between the networks is placed an important issue due to the intermediate attacks. Several types of research introduce the trust-based communication protocol for overcoming privacy issues but still, the efficiency of the trust is one of the major problems. So, this paper introduces the optimised trust and energy efficient multipath routing protocol based on the maintained energy of the node to overcome the issues. The intermediate attack in the network has been eliminated with the help of the trust and dynamic with energy efficient multipath routing protocol. The established trust has been used for a multipath routing protocol. Then, the efficiency of the system is analysed using the packet delivery ratio and security. The method ensures the trust in the network by applying the computation, aggregation, and propagation and prediction process.

Self-adaptive trust based ABR protocol for MANETs using Q-learning.

Mobile ad hoc networks (MANETs) are a collection of mobile nodes with a dynamic topology. MANETs work under scalable conditions for many applications and pose different security challenges. Due to the nomadic nature of nodes, detecting misbehaviour is a complex problem. Nodes also share routing information among the neighbours in order to find the route to the destination. This requires nodes to trust each other. Thus we can state that trust is a key concept in secure routing mechanisms. A number of cryptographic protection techniques based on trust have been proposed. Q-learning is a recently used technique, to achieve adaptive trust in MANETs. In comparison to other machine learning computational intelligence techniques, Q-learning achieves optimal results. Our work focuses on computing a score using Q-learning to weigh the trust of a particular node over associativity based routing (ABR) protocol. Thus secure and stable route is calculated as a weighted average of the trust value of the nodes in the route and associativity ticks ensure the stability of the route. Simulation results show that Q-learning based trust ABR protocol improves packet delivery ratio by 27% and reduces the route selection time by 40% over ABR protocol without trust calculation.

Trust and Shortest Path Selection based Routing Protocol for MANET

Mobile Ad hoc Network (MANET) comprises a Collection of wireless nodes that does not rely on any fixed infrastructure or base station. Trust based routing in MANET is challenging task due to its on demand dynamic nature which makes it susceptible to various types of attacks such as black holes, Byzantine, rushing attacks etc. The proposed trust based Management framework gives an overview about trust in MANETs. It works on the concept of trust factor in (initialization phase), for selecting the most efficient route and a routing path is evaluated using the concept of trust value that is updated during the route exchange process. The performance metric considered are throughput, number of drop packets and packet delivery ratio (PDR). The simulation results show that the proposed protocol gives better performance than existed protocol.

Different Ways to Achieve Trust in MANET

MANET (Mobile Ad-hoc Network) is hot spot for research due to its various advantages and disadvantages. Providing safe communication between mobile nodes, recognization the position of nodes, reducing overhead, handling misbehavior and location updates are such a difficult issues in ad-hoc network, so providing trust schemes is an important in this network. MANET provides some basic functions like routing, communication, network management and packet forwarding etc over self organized network. Because MANET has not a fixed topology, in which mobile nodes comes and leaves the network within a random period of time. It effects energy, bandwidth and memory computations of network. Providing trust in MANET is such a crucial task because it doesn’t having centralized infrastructure. In this paper, we survey the different trust model schemes of MANET with their unique features, merits and demerits & findings.

A Survey on Trust Management for Mobile Ad Hoc Networks

Managing trust in a distributed Mobile Ad Hoc Network (MANET) is challenging when collaboration or cooperation is critical to achieving mission and system goals such as reliability, availability, scalability, and reconfigurability. In defining and managing trust in a military MANET, we must consider the interactions between the composite cognitive, social, information and communication networks, and take into account the severe resource constraints (e.g., computing power, energy, bandwidth, time), and dynamics (e.g., topology changes, node mobility, node failure, propagation channel conditions). We seek to combine the notions of "social trust" derived from social networks with "quality-of-service (QoS) trust" derived from information and communication networks to obtain a composite trust metric. We discuss the concepts and properties of trust and derive some unique characteristics of trust in MANETs, drawing upon social notions of trust. We provide a survey of trust management schemes developed for MANETs and discuss generally accepted classifications, potential attacks, performance metrics, and trust metrics in MANETs. Finally, we discuss future research areas on trust management in MANETs based on the concept of social and cognitive networks.

Security Through Collaboration and Trust in MANETs

It is well understood that Mobile Ad Hoc Networks (MANETs) are extremely susceptible to a variety of attacks, and traditional security mechanisms do not work well. Many security schemes have been proposed that depend on cooperation amongst the nodes in a MANET for identifying nodes that are exhibiting malicious behaviors such as packet dropping, packet modification, and packet misrouting. We argue that in general, this problem can be viewed as an instance of detecting nodes whose behavior is an outlier when compared to others. In this paper, we propose a collaborative and trust-based outlier detection algorithm that factors in a node's reputation for MANETs. The algorithm leads to a common outlier view amongst distributed nodes with a limited communication overhead. Simulation results demonstrate that the proposed algorithm is efficient and accurate.

We describe and discuss existing models for these operations and highlight their specific problems. Considering routing protocols usage, we propose new solutions based on protocol modifications and distributed certifications that can be integrated to establish trust relationships for MANET operation and utilization.
