Smart Strategies for Energy-Aware Rouge Node Detection in Mobile Ad-hoc Networks

Given the exponential growth in interest, vehicle ad-hoc networks, or VANETs, have received considerable attention. Because there is no infrastructure or central monitoring body, the nodes self-organize. Routing and data transmission are carried out collaboratively by the nodes. “Currently, they are extensively utilized across various sectors, including disaster management, context-aware computing, business partnerships, military operations, and emergency response coordination following a fire. Consequently, security emerges as a paramount concern and necessity. This paper delves into ad-hoc networks, aiming to uncover malicious nodes within the network. Within the vast array of VANET classifications, this study predominantly focuses on a multi-parameter optimized approach for identifying and isolating rogue nodes in vehicular networks. An approach to trust optimization has been devised, integrating factors such as energy consumption, average velocity, message traffic, end-to-end latency, packet loss, and throughput. The proposed optimization strategy surpasses previous studies in terms of effectiveness, achieving an efficiency rate of 90% in handling rogue nodes.

I. Introduction

VANET is a word that refers to vehicle nodes that are not connected by wires, i.e. are wireless, resulting in a transitory network that does not require the assistance of a fixed central administering agent. Nodes connect directly with other entities for any necessity of communicating purpose that is within their transmission range [12]. Outside of their transmission range, nodes can still communicate, and this way of communication is accomplished through multi-hop scenario transfer to nodes that are not in their transmission range. Essentially, multi-hop transmission is defined as a packet that, after being sent across intermediate nodes of the network engaging in data flow, arrives at the end or destination node using any of the routing strategies in use [10]. Cooperation is essential among these data exchange nodes, since it leads to successful information reception all the way to the end or destination. Cooperation is a term used here to describe the group performance of network configuration functions by nodes. The converse can waste a lot of energy and resources while not producing the desired results [24].
