A fuzzy trust-based routing model for mitigating the misbehaving nodes in mobile ad hoc networks

Abstract

Purpose Security is one of the major challenges in the design and implementation of protocols for mobile ad hoc networks (MANETs). In such systems, the cooperation between nodes is one of the important principles being followed in the current research works to formulate various security protocols. Many existing works assume that mobile nodes will follow prescribed protocols without deviation. However, this is not always the case, because these networks are subjected to a variety of malicious attacks. Since there are various models of attack, trust routing scheme can guarantee security and trust of the network. The purpose of this paper is to propose a novel trusted routing model for mitigating attacks in MANETs. Design/methodology/approach The proposed model incorporates the concept of trust into the MANETs and applies grey relational analysis theory combined with fuzzy sets to calculate a node’s trust level based on observations from neighbour nodes’ trust level, these trust levels are then used in the routing decision-making process. Findings In order to prove the applicability of the proposed solution, extensive experiments were conducted to evaluate the efficiency of the proposed model, aiming at improving the network interaction quality, malicious node mitigation and enhancements of the system’s security. Originality/value The proposed solution in this paper is a new approach combining the fundamental basics of fuzzy sets with the grey theory, where establishment of trust relationships among participating nodes is critical in order to enable collaborative optimisation of system metrics. Experimental results indicate that the proposed method is useful for reducing the effects of malicious nodes and for the enhancements of system’s security.

Integrating Intelligent Systems in MANET- IoT Environment based on Subjective Context

“…The first determines optimal cluster heads, while the second calculates trust values and energy-efficient paths for secure connections.A. Beghriche and A. Bilami [16] introduced a novel blend of trust, fuzzy theory, and gray theory in MANET, aiming to establish trust levels among neighboring nodes. This approach facilitates routing decision-making by establishing trust relationships among network nodes.P.K.…”

Hybrid Trust and Weight Evaluation Based Trust Assessment Using ECK-ANFIS and AOMDV-REPO Based Optimal Routing in MANET Environment

“…However, Trust assessment wasn't an automatic system and regarded fewer link metrics aimed at trust evaluation. Again in 2018, Abdesselem Beghriche and Azeddine Bilami [22] offered a trusted routing intended for alleviating attacks. The conception of trust was integrated in the MANETs as well as grey relational examination theory united with fuzzy sets was applied for gauging a node's Trust Level (TL) centered upon observations as of neighbor nodes' TL.…”

Data replication techniques in the mobile ad hoc networks

“…The nodes move arbitrarily and establish themselves subjectively. The MANETs are infrastructure-less networks, so there is no need for immovable infrastructure for their actions (Beghriche and Bilami, 2018; Hoebeke et al , 2004). When the strength of the signal for radio received by the receiver is exceeded, a wireless connection is created between a transmitter and a receiver (Giordano, 2002; Petrovčič et al , 2016).…”
