Existing System:
Providing security is very challenging

IDS has been produced for giving
security. In this area, we
fundamentally portray three exhibited
approaches namely, Watchdog,
TWOACK, and Adaptive
Acknowledgment (AACK).

● Marti anticipated method watchdog for detecting misbehaving node
which is Unsafe for network. It operates in two phase first is Watchdog
and second is pathrater. It uses its next hops transmission for detecting
the misbehaving attack which is present in the network. It increases its
failure counter if next node fails to transfer packet within time limit.
Whenever a node’s failure counter surpasses a predefined threshold, the
Watchdog node reports it as misbehaving. The pathrater technique used
for in any future route selections for avoiding the use of malicious node
in the network.

● Some of the drawbacks which are present in previous IDS, such as
limited transmission power and receiver collision to avoid these
limitation and to increase the performance of network TWOACK schema
is proposed .It uses three consecutive node to transfer packet from
source to destination.
7

● It consist the combination of TWOACK and TACK. It transfer packet
from the first node to last node. Destination node gives feedback to first
node. It gives the good result than the watchdog and TWOACK. But
drawbacks of the AACK are it is not suitable for when there is number
node in the network is large.

Eaack—a secure intrusion detection.pptslksagar

This document proposes a secure intrusion detection system called EAACK for mobile ad hoc networks (MANETs). It discusses problems with existing IDS approaches for MANETs like Watchdog and TWOACK. The EAACK scheme aims to solve these problems by utilizing three parts: ACK, S-ACK and MRA. ACK uses end-to-end acknowledgment, S-ACK is an improved version of TWOACK, and MRA is used to resolve weaknesses in detecting misbehaving nodes. The objectives of this research are to study existing IDS schemes for MANETs, implement an IDS using the EAACK scheme, utilize digital signatures, and evaluate EAACK's performance compared to other approaches.

Enhanced Adaptive ACKnowledgment (EAACK)AAKASH S

The migration to wireless network from wired network has been a global trend in the past few decades. The mobility and scalability brought by wireless network made it possible in many applications. Among all the contemporary wireless networks, Mobile Ad hoc NETwork (MANET) is one of the most important and unique applications. On the contrary to traditional network architecture, MANET does not require a fixed network infrastructure; every single node works as both a transmitter and a receiver. Nodes communicate directly with each other when they are both within the same communication range. Otherwise, they rely on their neighbors to relay messages. The self-configuring ability of nodes in MANET made it popular among criticalmission applications like military use or emergency recovery. However, the open medium and wide distribution of nodes make MANET vulnerable to malicious attackers. In this case, it is crucial to develop efficient intrusion-detection mechanisms to protect MANET from attacks. With the improvements of the technology and cut in hardware costs, we are witnessing a current trend of expanding MANETs into industrial applications. To adjust to such trend, we strongly believe that it is vital to address its potential security issues. In this paper, we propose and implement a new intrusion-detection system named Enhanced Adaptive ACKnowledgment (EAACK) specially designed for MANETs. Compared to contemporary approaches, EAACK demonstrates higher malicious- behavior-detection rates in certain circumstances while does not greatly affect the network performances.

The document proposes a new intrusion detection system called EAACK that is designed specifically for mobile ad hoc networks (MANETs). Existing intrusion detection systems for MANETs have weaknesses including being vulnerable to false misbehavior reports and forged acknowledgment packets. EAACK addresses these weaknesses by using digital signatures to authenticate acknowledgment packets and thereby guarantee their validity. This helps EAACK more accurately detect malicious nodes and behaviors. The system is also designed to reduce network overhead compared to previous acknowledgment-based approaches.

The document describes EAACK, a secure intrusion detection system for mobile ad hoc networks (MANETs). It discusses how earlier IDS like Watchdog, TWOACK and AACK had limitations that EAACK addresses. EAACK combines three schemes - ACK, S-ACK and MRA to detect malicious nodes. The ACK scheme provides end-to-end acknowledgment with low overhead. S-ACK detects misbehavior using digital signatures across node groups. MRA authenticates misbehavior reports to prevent false reports. Simulation results show EAACK achieves high detection rates with minimal performance impact.

Performance Enhancement of Intrusion Detection System Using Advance Adaptive ...ijceronline

Mobile Ad hoc networks (MANETs) consist of a set of mobile nodes which can move about freely and are very sensitive to security threats due to their nature of deployment such as open wireless system. MANETs have self-configuring ability of nodes and infrastructure less nature hence they are preferred in significant applications. This itself emphasizes the importance of security and the need for an efficient intrusion detection system in MANETs. Many IDS have been proposed for detecting malicious nodes. On such different IDS, Enhanced Adaptive Acknowledgment (EAACK) has overcome the drawbacks of Watchdog, ACK and TWOACK. In our proposed work we have identified the inadequate nature of EAACK in scenarios of link breakage, source maliciousness. High mobility of MANET nodes contributes to frequent link breakages in the network which leads to path failures and route discovery processes difficult. Route discovery is initialized through broadcast mechanism usually. In this paper a new intrusion detection system is proposed named Advance EAACK particularly designed for MANETs. Compared to modern approaches, advance EAACK demonstrates higher malicious behavior detection rates in certain conditions while does not affect the network performance greatly. Due to this mechanism data transformation between mobile nodes are done with improved or high security .Parameters going to measure network performance are packet delivery ratio and delay.

INTRUSION IDENTIFICATION IN MANET USING ENHANCED ADAPTIVE ACKNOWLEDGEMENTInternational Journal of Technical Research & Application

A network is nothing but multiple nodes are connected with each other in some manner. The communication between each node and the topology of the network are important to make the environment more efficient. The communications between systems are broadly categorized into two; that are wired and wireless communication. In wired network, each node will be connected through physical wires and follows a topology. But in wireless network the communication between each node will be happen a centralized node called Access Point. In wireless environment a special wireless network is called MANET, in which there will be no centralized Access Points. MANET is nothing but Mobile Ad-hoc NETwork. In MANET each node acts as a sender and receiver. And there is no fixed route between nodes. Based on the nodes reachable, node will change the routing table dynamically. So the mobility and scalability of the nodes will not impact the MANET. The self-configuring ability of the MANET made it popular in military applications and emergency recovery. So the communication between each node should be more secure and trustable. And it’s important to identify the malicious nodes in MANET too. The malicious nodes are nodes which are not able to sends packets further or the nodes which are sends false report to the sender. To identify these malicious nodes and sends the messages with more secure with authorization need to implement new Intrusion Identification System called Digital Signature with Acknowledgement name as Enhanced Adaptive Acknowledgement. The objective of MANET is fast communication. So its need to analyze the network throughput also once the new Intrusion Identification System introduced.

1) Wireless sensor networks consist of hundreds or thousands of low-cost, low-power sensor nodes deployed to monitor environments. They require security to protect data confidentiality, integrity, and availability given their resource constraints and vulnerability to physical attacks. 2) Standard approaches to achieve security include encrypting data for confidentiality, using protocols like uTESLA for integrity and time synchronization for freshness. However, sensor nodes face obstacles like limited memory, energy constraints, and unreliable communication. 3) Wireless sensor networks are susceptible to various network layer attacks like spoofing, selective forwarding, sinkhole attacks, Sybil attacks, and wormholes. Countermeasures include link layer security, geographic routing, multi-path routing, and authentication.

Threats in wireless sensor networksPriya Kaushal

Wireless sensor networks require a high level of security even though their resources are limited. They face many types of attacks due to their broadcast transmissions and deployment in hostile environments without physical protection. Attacks can target the information in transit, different layers of the protocol stack, and seek to overwhelm the network. While some challenges have been addressed, research is still needed to resolve conflicts between security and limited resources in wireless sensor networks.

Selective watchdog technique for intrusion detection in mobile ad hoc networkgraphhoc

Mobile ad-hoc networks(MANET) is the collection of mobile nodes which are self organizing and are connected by wireless links where nodes which are not in the direct range communicate with each other relying on the intermediate nodes. As a result of trusting other nodes in the route, a malicious node can easily compromise the security of the network. A black-hole node is the malicious node which drops the entire packet coming to it and always shows the fresh route to the destination, even if the route to destination doesn't exist. This paper describes a scheme that will detect the intrusion in the network in the presence of black-hole node and its performance is compared with the previous technique. This novel technique helps to increase the network performance by reducing the overhead in the network

SR-Code: Smart Relay Network Coding for Data Collection for Wireless Sensor N...IJERA Editor

Reliability in data collection for wireless sensor networks is one of the major problems in IoT applications. Sensor nodes are usually placed in harsh conditions where data communication is at risk of losing packets. Retransmissions are considered costly in terms of delay and power consumptions, especially that wireless sensor nodes are battery operated. In this context we introduce SR-Code, a novel network coding algorithm that achieves reliability in harsh conditions. SR-Code utilizes the XOR operator to code overheard packets. The targeted network topology is a 2-tier network where data loss can occur in all tiers. SR-Code utilizes bit addresses where each node is identified by a single bit in an address bit vector. Identifying packets and computing the cardinality of coded messages can be easily done using address bit vectors. SR-Code realizes redundancy as a function of overheard packet. SR-Code achieved a reliability factor of 75% when the number of packets lost was 100% of the original (un-coded) packet sent.

This document discusses enhancing security in mobile ad hoc networks (MANETs) using a hybrid cryptography algorithm. It first provides background on MANETs and existing intrusion detection systems like EAACK that use digital signatures. The proposed system aims to improve on EAACK by using a hybrid of symmetric (AES) and asymmetric (RSA) cryptography. RSA would provide authentication through digital signatures, while AES would handle integrity and confidentiality in a way that reduces network overhead compared to using digital signatures alone. The goal is to achieve better security and integrity than EAACK through this combined cryptographic approach.

Performance Analysis of MAC Layer Protocols for WSN with Considering the Effe...BRNSSPublicationHubI

This document summarizes a research article that analyzed the performance of three MAC layer protocols (IEEE 802.11, IEEE 802.15.4, and TDMA) in a wireless sensor network considering the effects of the hidden node problem. Six performance metrics were evaluated: goodput, throughput, packet delivery ratio, residual energy, average delay, and node lifetime. The results showed that TDMA provided the best energy conservation and highest delay, while IEEE 802.11 gave the best throughput and goodput as well as lowest delay. IEEE 802.15.4 and TDMA were better than IEEE 802.11 at mitigating the hidden node problem.

“Reducing packet loss in manet”Alexander Decker

This document summarizes a research paper on reducing packet loss in mobile ad hoc networks (MANETs). The paper discusses how MANETs are vulnerable to various security threats like black hole attacks that can cause packet dropping. It evaluates existing authentication schemes like ACK-based schemes that have overhead issues. The paper then proposes a modified ACK-based scheme using finite state automata to overcome decision ambiguity and minimize packet dropping while authenticating nodes in the MANET. Simulation results show that the proposed approach improves packet delivery ratio, throughput and reduces routing load compared to not using secure authentication.

Minimizing mobiles communication time using modified binary exponential backo...IJCNCJournal

The domain of wireless Local Area Networks (WLANs) is growing speedily as a consequence of developments in digital communications technology. The early adopters of this technology have mainly been vertical application that places a premium on the mobility offered by such systems. Examples of these types of applications consist of stocking control in depot environments, point of sale terminals, and rental car check-in. Furthermore to the mobility that becomes possible with wireless LANs; these systems have also been used in environments where cable installation is expensive or impractical. Such environments include manufacturing floors, trading floors on stock exchanges, conventions and trade shows, and historic buildings. With the increasing propagation of wireless LANs comes the need for standardization so as to allow interoperability for an increasingly mobile workforce. Despite all the advantages and facilities that Wi-FI offers, there is still the delay problem that is due to many reasons that are introduced in details in our case study which also presents the solutions and simulation that can reduce this delay for better performance of the wireless networks

Tees an efficient search scheme overKumar Dlk

The document proposes TEES (Traffic and Energy saving Encrypted Search), an architecture for efficient encrypted search over mobile cloud storage. TEES aims to reduce computation time, energy consumption, and network traffic for file retrieval compared to traditional encrypted search schemes. It offloads computation of relevance scores from mobile devices to the cloud to reduce energy usage. It also simplifies the search and retrieval process to reduce network traffic and retrieval time through a single communication round trip. TEES enhances security by adding noise to term frequency distributions and hiding the association between keywords and files. Experiments show TEES reduces computation time by 23-46% and energy consumption by 35-55% compared to traditional schemes.

The role of wall art in interior designingmeghaark2110

Wall art and wall patterns are not merely decorative elements, but powerful tools in shaping the identity, mood, and functionality of interior spaces. They serve as visual expressions of personality, culture, and creativity, transforming blank and lifeless walls into vibrant storytelling surfaces. Wall art, whether abstract, realistic, or symbolic, adds emotional depth and aesthetic richness to a room, while wall patterns contribute to structure, rhythm, and continuity in design. Together, they enhance the visual experience, making spaces feel more complete, welcoming, and engaging. In modern interior design, the thoughtful integration of wall art and patterns plays a crucial role in creating environments that are not only beautiful but also meaningful and memorable. As lifestyles evolve, so too does the art of wall decor—encouraging innovation, sustainability, and personalized expression within our living and working spaces.

The History of Kashmir Karkota Dynasty NEP.pptxArya Mahila P. G. College, Banaras Hindu University, Varanasi, India.

This slide is an exercise for the inquisitive students preparing for the competitive examinations of the undergraduate and postgraduate students. An attempt is being made to present the slide keeping in mind the New Education Policy (NEP). An attempt has been made to give the references of the facts at the end of the slide. If new facts are discovered in the near future, this slide will be revised. This presentation is related to the brief History of Kashmir (Part-I) with special reference to Karkota Dynasty. In the seventh century a person named Durlabhvardhan founded the Karkot dynasty in Kashmir. He was a functionary of Baladitya, the last king of the Gonanda dynasty. This dynasty ruled Kashmir before the Karkot dynasty. He was a powerful king. Huansang tells us that in his time Taxila, Singhpur, Ursha, Punch and Rajputana were parts of the Kashmir state.

Improved eaack develop secure intrusion detection system for mane ts using hybrid cryptography

1. Improved EAACK: Develop Secure Intrusion Detection System for MANETs Using Hybrid Cryptography

2. ABSTRACT Data transfer rate is more in wireless network as compared to wired network. Wireless network gives more advantageous because its support feature such as versatility, portability, open medium, simple to design. MANETs and WSN are the most common forms of Wireless media. In MANETs nodes are deployed or distributed in Ad- hoc way and they are communicating or exchange message using wireless Transmission. Data transfer rate is more in wireless network as compared to wired network. Wireless network gives more advantageous because its support feature such as versatility, portability, open medium, simple to design. MANETs and WSN are the most common forms of Wireless media. In MANETs nodes are deployed or distributed in Ad-hoc way and they are communicating or exchange message using wireless Transmission. 2

3. Existing System: Providing security is very challenging task in MANETs. There are numerous IDS has been produced for giving security. In this area, we fundamentally portray three exhibited approaches namely, Watchdog, TWOACK, and Adaptive Acknowledgment (AACK). 3

4. 1.Watchdog Schema:

5. ● Marti anticipated method watchdog for detecting misbehaving node which is Unsafe for network. It operates in two phase first is Watchdog and second is pathrater. It uses its next hops transmission for detecting the misbehaving attack which is present in the network. It increases its failure counter if next node fails to transfer packet within time limit. Whenever a node’s failure counter surpasses a predefined threshold, the Watchdog node reports it as misbehaving. The pathrater technique used for in any future route selections for avoiding the use of malicious node in the network. 5

6. 2. Two ACK Schema:

7. ● Some of the drawbacks which are present in previous IDS, such as limited transmission power and receiver collision to avoid these limitation and to increase the performance of network TWOACK schema is proposed .It uses three consecutive node to transfer packet from source to destination. 7

8. 3. AACK:

9. ● It consist the combination of TWOACK and TACK. It transfer packet from the first node to last node. Destination node gives feedback to first node. It gives the good result than the watchdog and TWOACK. But drawbacks of the AACK are it is not suitable for when there is number node in the network is large. 9

10. ➜ Ambiguous collisions ➜ Receiver collisions ➜ Limited transmission power ➜ False misbehavior report ➜ Collusion ➜ Partial dropping Disadvantages: 10

11. Proposed Work: The proposed system comprises the following modules: 11

12. ➜ Acknowledgement (ACK). ➜ S- Acknowledgement (S-ACK). ➜ Misbehavior Report Authentication (MRA). 1.EAACK ➜ Acknowledgement (ACK). ➜ S- Acknowledgement (S-ACK). ➜ Misbehavior Report Authentication (MRA). 12

13. HYBRID ENCRYPTION AND DECRYPTION A hybrid cryptosystem is one which combines the convenience of a public-key cryptosystem with the efficiency of a symmetric-key cryptosystem. In this project we are using Triple DES Algorithm is a symmetric-key cipher, which applies the DES cipher algorithm three times to each data block. It is very easy to modify existing software to use Triple DES. 13

14. ➜ EAACK gives better performance than other schema. ➜ EAACK uses digital signature it causes routing Overhead. ➜ Hybrid cryptography to reduce routing overhead by detecting malicious path. Using shared key source node and destination node authenticate to transfer data Packet Advantages: 14

15. Algorithm: Hybrid Cryptography Triple DES Algorithm EAACK schema 15

16. OUR PROCESS IS EASY Base Paper Project Document 16
