Wireless networks are a combination of nodes or computers or devices which are communicate with each other in network communication. In wireless network communication security is an emerging challenge task. Some of the attacks occur in wireless ad hoc networks because of increase internal activities in data communication. AODV (Ad hoc On-Demand Distance Vector) is an aimed to detect intrusion detection attacks, implementation to detect intruder and provide solution to reduce packet delivery with respect to variative throughput based on data tranmission. To detect network valnerabilties in network communication with respect to intrusion and detection effectively, we implement Enhanced AODV (which consists both signature authentication and AODV), to improve performance of network interms of delivery ratio, throughput and bandwidth between nodes in static topology of wireless communication. Our experimental results ability of enhanced AODV succesfully detect distributed attacks with low false positive rates over wireless network communication.
Review of Flooding Attack Detection in AODV Protocol for Mobile Ad-hoc Network
IJSRD, 2013
Ad Hoc Networks are extremely vulnerable to attacks due to their dynamically changing topology, absence of conventional security infrastructures, vulnerability of nodes and channels and open medium of communication. Denial of Service (DoS) and Distributed DoS (DDoS) attacks are two of the most harmful threats to the network functionality. The Prevention methods like authentication and cryptography techniques alone are not able to provide the security to these types of networks. Therefore, efficient intrusion detection must be deployed to facilitate the identification and isolation of attacks. Major attacks on Mobile Ad hoc networks are flooding, selective forwarding, sinkhole, wormhole etc. We have presented various intrusion detection techniques in MANET. Then we have proposed a method to detect flooding attack in MANET.
Security enhancement of AODV protocol for mobile Ad hoc Network
International Journal of Managment, IT and Engineering, 2013
Here, authors presents a smart encryption algorithm integrated with existing AODV protocol that enhances the security of routing in MANET. Mobile Ad hoc Network's because of maliciousness that intentionally disrupts the network by using variety of attacks and due to routing protocols (e.g. AODV), which were already developed without considering security features to prevent the various kinds of attacks. And also there is infrastructure less environment, and having open peer-to-peer architecture, shared wireless medium and dynamic topology, MANETs are frequently established in insecure environments like disaster sites and military applications. Ad-hoc On-Demand Distance Vector (AODV) is widely used routing protocol. Author's strategy is to choosing one of the secure routing protocols among all according to its effectiveness. It is analyzed by its functionality and performance measurements. Then, the different existing security techniques (e.g. encryption algorithm.) were surve...
IRJET- Sybil Attack Detection in Mobile Ad-hoc Networks using AODV protocol
IRJET, 2021
Mobile ad hoc networks are a technology that enables fast, easy, and inexpensive network deployment, but unfortunately these benefits also make an attacker's job easier by making it easier to deploy a malicious node in the environment. Mobile ad Hoc networks are prone to various attacks because of the broadcast nature of the wireless medium and the lack of a central authority. In this proposed work, we created a real network scenario that offers a more accurate solution to the attack. We performed a topology analysis based on the routing protocol and found that the AODV protocol performed better than other routing protocols. Since wireless network security is a major concern, the Sybil attack affects the performance. In a Sybil attack, an adversary illegitimately claims to have multiple imaginary identities called Sybil nodes. This attack is capable of compromising various operations on these networks, such as data aggregation, coordination mechanisms based on , fair resource allocation schemes, detection of bad behavior and routing mechanisms. In our research, we implemented the attack in a real-time network scenario and compared the results with the normal AODV protocol, the AODV protocol with the Sybil attack and the AODV protocol after mitigation technique.
A Survey of various Methods of Preventing and Detecting Attacks on AODV-based MANET
Mobile Ad hoc Network (MANET) is constructed from a collection of nodes that can move anywhere and anytime in different areas without any infrastructure that means MANET is infrastructure less. Each node works at the same time as router and host. Lack of a fixed infrastructure, wireless medium and dynamic topology makes MANET vulnerable to different kinds of attacks like Gray hole and Black hole. In this paper, we investigate different mechanisms that have designed to detect or prevent black or gray hole attacks in AODV protocol. We discuss about advantages and disadvantages of the different methods.
Performance Enhanced AODV Routing Protocol Security in Mobile Ad-Hoc Networks
International Journal of Technology Diffusion, 2012
With the emergence of mobile ad-hoc networks, more users desire connectivity regardless of geographic location. MANETs are a promising technology in terms of the applications in the military, emergency situations, and general daily life activities. Various protocols have been developed to handle the routing information in such networks. However, most protocols are vulnerable to various threats. Among them, the Black-hole type of denial-of-service attack causes a major degradation in the performance and trust of the network nodes. In this paper, the authors review and highlight the limitations of the existing solutions and propose a new algorithm to handle the black-hole attacks. The proposed algorithm is comparatively efficient and easy to implement for detecting and avoiding the black-hole attacks. The proposed algorithm has been implemented in Network Simulator (ns-2) to evaluate its performance in term of packet delivery ratio, network load, and end-to-end delay. The simulation r...
