Operating in ad-hoc mode allows all wireless devices within range of each other
to discover and communicate in a peer-to-peer fashion without involving central
access points. Many routing protocols like AODV, DSR etc have been proposed for
these networks to find an end to en...

... can also send false RREP packet to the source to advertise that it has the shortest path to destination. A black hole can easily intercept the packets for a particular destination. As an example, consider Figure. 4 as a network scenario with F as a black hole attacker intercepting packets of node E. When it receives a RREQ packet for E say from A, then it replies back to A with a RREP packet informing that it is having shortest path to E. Now as per working of AODV routing protocol A assumes that shortest path to E is from F and sends all the ...

Numerous technologies are being evolved in the everyday life. The researchers' concentration is gained increasingly by these growing modern technologies. A Mobile Ad-hoc Network (MANET) is a self-configuring along with a self-organizing network devoid of an infrastructure utilized by wireless mobile devices. Several kinds of security measures are being adopted; even then, there occur attacks often. Innovative methodologies are invented by the attacker for attacking. To guard data numerous technologies have been established whereas simultaneously, another methodology will be implemented to hack the information. All the technology is comprised of pros and cons, in the same way, MANETS are also included in that category. The MANETS' security threats, challenges, along with complications are reviewed in this paper. The various methodologies utilized in the latest literature to sort out the MANETS' security problems are significantly surveyed in this manuscript. On the regions of identification of malicious activity, malicious node detection, methodologies, performance evaluation, along with Energy Consumption (EC), the theoretical interpretation is performed.

Mobile Ad-hoc Networks or MANETs are mostly found where any fixed facilities are not available and so it is dynamic. Secure transmission of data is an important aspect in MANET. They have unique characteristics like dynamic topology, wireless radio medium and lack of centralized administration. As a result they are vulnerable to different types of attacks in different layers of protocol. To protect these networks, various security protocols have been developed. To address these issues, a framework called Security Using Pre-Existing Routing for Mobile Ad-hoc Networks (SUPERMAN) [ 1 ] is proposed. This paper presents a security framework SUPERMAN which enables data confidentiality and prevention of data loss by using AES encryption. And a report is generated at the destination side to view user details, path details and attack node details.

Compared to wired-infrastructure dependent networks, Mobile Ad Hoc Networks (MANETs) are more vulnerable to attacks. Because of their dynamic topology and the absence of centralized network administration, MANETs face more security threats than centralized networks. Initial literature review on MANETs' security issues indicates that while there have been attempts to identify security threats and solutions on MANETs, comprehensive reviews are very little or lacking. In an attempt to address this gap, this article offers an up-to-date literature on security issues and solutions in MANETs. By limiting the review to 21 st Century research on this topic, this review paper is able to offer a comprehensive presentation of the issues concerning security in MANETs.

A Mobile Ad hoc Network (MANET) is a decentralized infrastructure-less network where wireless nodes move arbitrarily. Every node has limited energy that is provided by battery. Some operations like taking part in finding rout, forwarding packets and receiving packets consume energy. So there are some nodes that are not willing to cooperate and want to save their energy called selfish. These nodes affect network performance and security. Recently security is one of the major challenges in network. So in this paper for detecting selfish nodes we proposed a new routing protocol.

Mobile ad-hoc network is an infrastructure-less and self-organizing network, where nodes communicate through wireless links. Because of its dynamic topology, security becomes a vital issue compared to infrastructure networks. MANETs are more vulnerable to various types of security attacks due to the absence of trusted centralized authority. Several routing protocols have been proposed for these networks to establish an end to end link for communication between the nodes. These protocols are prone to attacks by the malicious nodes and there is always a need to detect and prevent the attacks timely before the collapse of network. In this paper the focus lies on current routing attacks, security issues of ad-hoc networks and solutions to mitigate attacks against the routing protocols based on cooperation between nodes in network.

Assaults on such type of network where there is mobility, are comprehensively partitioned into two noteworthy classiications: Active Attacks: In this kind of attacks 4,15 the attackers try to agitate the original functionality of the transmitting and communicating devices in the network. his task is carried by evaluating the information and changing the packets which contain the information, denial of neither services 13 nor changing the path desired for routing by modifying the route specifying path, count of hops in a path etc. hese kinds of active attacks can easily be identiied and detected when compared with the other opposite attacks called Inactive (Passive) attacks. ...
