Wireless technology has become a prominent force in shaping entertainment, communication, and education worldwide. The significance of today's wireless technology is undeniable, as it finds extensive applications. In Ad-hoc network communication, nodes connect directly with each other, functioning as both routers and hosts. This interconnectedness allows seamless data sharing among nodes. A specific type of Ad-hoc network is the Vehicular Ad-hoc Network (VANET), which facilitates communication between vehicles and road-side base stations, aiming to enhance transportation efficiency and safety.

 

In the pursuit of safe transportation, the design of efficient routing protocols and robust security measures becomes paramount. Ensuring secure data transfer between nodes is essential, especially when dealing with sensitive information. In the past, early routing protocols for Mobile Ad-hoc Networks (MANETs) often overlooked security concerns. Recognizing the need for safeguarding data during communication, subsequent proposals incorporated strong cryptographic methods to protect routing information.

 

This article delves into the world of ad hoc networks and their crucial security protocols, shedding light on the intricacies of secure data transfer and communication between nodes.

INTRODUCTION

In modern times, wireless technology has revolutionized entertainment, communication, and education worldwide. Wireless networks, specifically Ad-hoc networks, operate without centralized access points or base stations, with each node acting as both a router and a host. Efficient security planning and well-designed routing protocols are essential for secure data transfer among nodes.

 

The proliferation of vehicles on roads has resulted in faster communication but also increased driving challenges and a higher risk of traffic accidents. To address this, vehicles must be capable of communicating with each other effectively. Vehicular Ad-hoc NETworks (VANETs) emerge as wireless networks that facilitate communication among vehicles within a limited range of a few hundred meters, providing safety features, awareness of traffic conditions, Internet access for passengers, and multimedia entertainment services.

 

The objective of this study is to offer users a seamless capability to transfer source information packets to destination nodes automatically and without intervention. MANETs consist of self-organizing nodes that rely on distributed behavior. Establishing routes is crucial for effective routing, even though it is unrealistic to assume continuous wireless access to roadside units. Precision in inter-vehicle, vehicle-to-roadside, and routing-based communications requires accurate positioning systems and smart communication protocols.

 

Ad hoc networks, consisting of mobile nodes forming instant networks without fixed topology, are compatible with conventional networks despite lacking permanent infrastructures. Due to the limited range of wireless transmissions, mobile hosts may need assistance from other hosts to forward packets to their destinations. Routing in Mobile Adhoc networks faces challenges due to bandwidth, battery power, CPU time constraints, and frequent topological changes caused by node mobility.

 

Mobile Ad-hoc networks operate with autonomous wireless nodes, functioning without a central node for management. Security is a significant challenge in Ad Hoc Networks, as the multi-hop nature of the network makes it susceptible to malicious attacks. VANETs possess unique characteristics such as time-varying vehicle density, time-critical safety applications, distributed communication, and high mobility, making information routing and high mobility maintenance complex tasks.

 

In this context, several topology-based routing protocols are described, including proactive and reactive protocols. These protocols play a vital role in Mobile Ad Hoc Networks, especially in applications like military battlefields, emergency rescue, vehicular communications, and mining operations. However, the flexibility of Ad Hoc Networks poses security challenges, making them more vulnerable to attacks compared to wired networks with fixed infrastructure.

 

Researchers have developed various routing protocols for MANETs with different performance levels. An evaluation of AODV, DSR, DSDV, OLSR, and DYMO routing protocols in different scenarios is conducted to determine the most suitable protocol. Performance evaluation is based on Packet Delivery Ratio, Average End to End Delay, Normalised Routing Load, and Average Throughput.

 

In summary, wireless ad hoc networks offer immense potential in a world where communication is indispensable, particularly in mobile communication. The ability of nodes to move without fixed infrastructure makes ad hoc networks temporary and adaptive. However, addressing security concerns and optimizing routing protocols are critical factors for ensuring efficient and secure data transfer within these networks.

PROBLEM STATEMENT

Since the advent of networks, numerous studies and research have been conducted to propose more efficient routing protocols, aiming to improve routing efficiency based on various parameters. However, much of the previous work has primarily focused on addressing the challenges of finding and maintaining correct routes to destinations amidst node mobility and changing network topology. There are two main issues that researchers have encountered: security protocols and ad-hoc networks.

 

The first problem revolves around the effectiveness of accessible routing protocols, especially when dealing with a large node population. As the number of nodes increases, traditional routing protocols may struggle to handle the increased complexity and scalability, resulting in diminished performance.

 

The second problem lies with reactive routing schemes. These schemes might fail to discover complete paths due to frequent network partitions or disruptions. This failure to establish a complete route can significantly impact communication reliability and overall network performance, posing a significant concern for both security protocols and the functioning of the ad-hoc network.

 

Addressing these challenges is critical for the development and enhancement of ad-hoc networks, ensuring secure and efficient data transmission even in dynamic and challenging environments. Researchers continue to explore innovative solutions and improvements to routing protocols, striving to overcome these limitations and optimize the performance of ad-hoc networks.

REVIEW  OF  LITERATURE

(Kim and Woon Lee, 2015) highlighted that Wireless Sensor Networks (WSNs) have become increasingly important for diverse applications like military target tracking, natural disaster relief, biomedical health monitoring, and hazardous environment sensing. WSNs consist of numerous low-cost, battery-powered sensor nodes with limited computation and communication capabilities. These nodes form an adaptive routing graph, continuously collecting data for events of interest and delivering it to a designated destination. However, hierarchical WSNs, where sensory data is periodically gathered in cluster heads and then forwarded to the sink, are vulnerable to malicious attacks. Security and routing mechanism designs specifically tailored for WSNs present challenging issues for researchers.

 

(Bokade_ et al., 2014) discussed Mobile Ad hoc Networks (MANETs), where nodes dynamically self-organize into temporary network topologies without infrastructure support. The dynamic topology and lack of a fixed infrastructure make routing challenging, as mobile hosts can act as both hosts and routers, forwarding packets for other nodes. The network connections change dynamically due to mobility, and nodes can join or leave the network at any time. The paper evaluated the performance of reactive routing protocols (AODV and DSR) and proactive routing protocol (DSDV) using the Network Simulator.

 

(Kumar, 2015) described reactive routing protocols as demand-based, where nodes establish connections only when needed. They consist of two major components: route discovery and route maintenance. Route discovery involves finding a route to the destination, while route maintenance handles changes in the network topology due to node mobility. It relies on acknowledgments to maintain the route's integrity.

 

(Gupta_ et al., 2015) emphasized that different protocols achieve varying results depending on the network configuration. The paper aimed to compare the performance of AODV, DSR, and TORA based on various parameters like average delay, network load, throughput, and load using simulation tools like OPNET, NS-2, and Qualnet.

 

(Jha and Kharga, 2015) discussed MANETs as self-configuring, infrastructure-less networks of mobile devices connected wirelessly. The dynamic topology, bandwidth constraints, and limited physical security present unique challenges. Routing protocols play a crucial role, and the paper focused on proactive and reactive routing protocols for ad hoc networks.

 

(Huang and Mu, 2015) explored RFID grouping proof protocols, a branch of RFID security technologies that authenticate tags and readers to achieve security, privacy, and matching requirements. The paper improved previous schemes with timestamp-based methods to address vulnerabilities and enhance security.

 

(Mannan and Khurana, 2014) defined MANETs as autonomous networks of mobile nodes communicating over wireless links. The dynamic topology and lack of infrastructure require each node to act as a host, router, and transmitter. The paper emphasized the significance of routing protocols in MANETs and discussed proactive and reactive routing protocols for these networks.

 

(Goyal, 2015) discussed Vehicular Ad hoc Networks (VANETs) as a specific class of MANETs, where the network topology changes rapidly due to high-speed vehicle movement. The paper compared the performance of reactive routing protocols (AODV and DSR) in terms of throughput, network load, and end-to-end delay with varying numbers of mobile nodes.

 

(Bhatia and Verma, 2015) highlighted MANETs as self-configured networks of mobile nodes with arbitrary topologies. Ad hoc networks rely on intermediate nodes to transmit data between source and destination. The paper emphasized the importance of routing in updating network topology information.

 

(Neeli and Cauvery, 2015) focused on AODV, a reactive distance vector routing protocol for MANETs. It uses route request and route reply messages to discover routing paths, and intermediate nodes reply only if they have a fresh route to the destination.

 

(Dong and Xie, 2015) emphasized the importance of integrating knowledge of cyber security, human interaction, and complex network design to enhance the resilience of Cyber-Physical Systems (CPS). The paper discussed the vulnerabilities in CPS systems and the possibility of attackers eavesdropping, tampering, or modifying control algorithms.

 

(Abdullah and Jassim, 2015) defined MANETs as networks of mobile nodes that can communicate without a centralized administrator or fixed infrastructure. The dynamic topology requires wireless nodes to function as both hosts and routers, and communication occurs via direct links or intermediate nodes in a multi-hop network.

OBJECTIVES

By addressing the challenges of data losses and collisions in communication, the study aims to decrease the chances of errors and enhance the overall reliability of data transfer. To achieve this, various methods and techniques of security protocols are examined and implemented.

 

One of the key factors considered in this research is the effect of node population on the effectiveness of accessible routing protocols. It is observed that when the node population is small, the routing protocols become more efficient, resulting in decreased error chances and minimized data collisions during communication.

 

Another critical aspect addressed is the impact of high mobility networks on communication reliability. The study explores and mitigates issues arising from network nodes constantly changing their positions. By ensuring that the shortest and most stable paths are utilized for data transfer, the study aims to ensure accurate and uninterrupted data transmission without compromising the integrity of the data.

 

Overall, the study focuses on enhancing the performance of security protocols by improving data transfer efficiency, minimizing errors, and ensuring secure and reliable communication between the source and destination. By adopting different methods and techniques, the study seeks to offer users an optimized and secure data transmission capability, meeting the demands of modern communication networks.
