To cope with the above adversary attack model, we design a light-weight trust management model according to existing modes [13], [14], [34]- [37]. The proposed model derives nodes' trust level based on two types of trust, direct trust from direct observations and indirect trust recommended by the third node.…”

The overhead caused by broadcast schemes cannot be neglected in mobile ad hoc networks. It is known that the probabilistic broadcast scheme is an effective approach to reduce overhead, in which nodes forward packets with a probability to reduce redundant retransmissions. In hostile environments, malicious nodes degrade network efficiency, and they should be prevented from route discovery and data transmission. In this case, routing packets forwarded by malicious nodes are redundant. This paper presents a Trust-based Probabilistic Broadcast scheme (TPB) focusing on reducing overhead, especially caused by malicious nodes, in which rebroadcast probability is determined based on nodes' trustworthiness. In order to obtain nodes' trust level, a lightweight trust management model is designed based on direct and recommended trust evidence. According to nodes' trust level, rebroadcast delay is calculated for rearranging the rebroadcast order of routing packets. Furthermore, a novel method based on nodes' trustworthiness is proposed to calculate rebroadcast probability, which prevents untrusted nodes from route discovery. The proposed trustbased probabilistic broadcast scheme is incorporated with existing routing protocol and its performance is evaluated by simulations. The numerical results show that the proposed scheme can secure network communication and reduce the routing overhead. INDEX TERMS Mobile ad hoc network, routing overhead, probabilistic broadcast, trust evaluation. I. INTRODUCTION A mobile ad hoc network (MANET) is a decentralized wireless network, which is composed of some mobile nodes spontaneously. The characteristics such as easy deployment, dynamic topology, self-configuration and multi-hop communication promote MANET based applications increasing demanded in many civilian and military fields, ranging from providing emergency communication in natural disasters and transmitting critical information on the battlefield. However, the performance of MANET is susceptible to routing overhead due to resource constraints in terms of wireless resource and computing power. Furthermore, MANET is vulnerable to attacks from malicious nodes because there is no centralized The associate editor coordinating the review of this manuscript and approving it for publication was Xu Chen.

“…Nowadays, the vehicular ad hoc network (VANET) [1] has emerged as a popular area for research because of the extensive increase in information traffic. This is said to be a unique model of MANET (Mobile ad hoc NETwork) [2, 3], which poses certain features. The characterisation of VANET [4] is made by multi‐hop with rapidly changed self‐organisation and high node speed network topology.…”

Summary In mobile ad hoc networks (MANETs), cooperative communication and resource constraint are the two important core characteristics essential to guarantee trusted data dissemination. The cooperative communication between mobile nodes depends on the trust rendered by them towards the process of reliable data routing. However, stringent resource constraints of mobile nodes such as energy, memory, communications, and computations result in the introduction of selfish and malicious node that completely degrades the network performance in different dimensions. In this paper, Z number improved reference ideal method (RIM)‐based decision‐making process (NIRIMDMP) is proposed with the merits of maximizing deviation method (MDM) and best–worst method (BWM) to ensure reliable data routing by modeling the cooperation degree in terms of Z number. This NIRIMDMP adopted Z number to represent the information reliability and handle the problem of inherent uncertainty during the process of evaluating each mobile node in the routing process. In specific, MDM and BWM are included into the proposed NIRIMDMP to determine comprehensive attribute weights based on the calculated objective and subjective weights that could be possible derived in routing. It extended the merits of classical RIM using Z numbers to confirm reliable ranking of mobile nodes, even when the optimal solution exists amid extreme values taken into consideration for assessing the mobile nodes during decision making. Simulation investigations of the proposed NIRIMDMP confirmed improved throughput and network lifetime with reduced control overhead, energy consumptions, and delay independent of the amount of malicious and non‐cooperative nodes.
