Wireless Ad Hoc Network Routing Protocols Performance Evaluation under Security Attack

Abstract

Abstract: A mobile ad hoc network is made up of portable wireless nodes (MANET). The communication between these mobile nodes is not managed centralized. A self-organizing, self-configuring network known as MANET allows mobile nodes to roam around at whim. The mobile nodes can act as a router by receiving and sending packets. Due to the significance of routing in MANET, this thesis also evaluates several routing systems' efficacy. We compared the three routing protocols AODV, DSR, OLSR, and DSDV. Throughput, network load, and latency are the three metrics used to gauge how well-performing different routing systems are. The three routing techniques are well described using metrics. Information is transmitted end-to-end and hop-by-hop over the connections to the destination nodes using the proactive and reactive protocols of MANET. In multi-hop mobile ad hoc networks, energy consumption at the mobile nodes' end and its effective use are crucial factors. Nodes and other routing resources in MANETs cannot afford to run out of battery power while carrying out mission-critical operations like military or rescue missions. The effectiveness of MANET protocols such AODV, DSDV, OLSR, and DSR is studied in this study. Throughput, packet delivery ratio, and energy use are included while computing the Mobile Ad-hoc Networks' performance parameters. The circumstances that were simulated using various simulators are included in the research. The related research compared the performance of several protocols in MANETs with varying node mobility, stop length, and node density while examining the NS-2 scenario. The optimum routing system for mobile ad hoc networks will be identified after a comparison and analysis of these protocols.
