The rapid growth of employing devices as tools in daily life and the technological revolution have led to the invention of a novel paradigm; the Internet of Things (IoT). It includes a group of ubiquitous devices that communicate and share data with each other. These devices use the Internet Protocol (IP) to manage network nodes through mobile ad hoc networks (MANET). IoT is beneficial to MANET as the nodes are self-organising and the information reach can be expanded according to the network range. Due to the nature of MANET, such as dynamic topology, a number of challenges are inherent, such as Denial of Service (DoS) attacks. DoS attacks prohibit legitimate users from accessing their authorised services. In addition, because of the high mobility of MANET, the network can merge with other networks. In this situation, two or more networks of untrusted nodes may join one another leaving each of the networks open to attack. This paper proposes a novel method to detect DoS attacks immediately prior to the merger of two MANETs. To demonstrate the applicability of the proposed approach, a Grayhole attack is used in this study to evaluate the performance of the proposed method in detecting attacks.

Using Trust Based Method to Detect DoS Attack in MANETs

ملخص المشاركة:

A mobile ad hoc network (MANET) consists of nodes that communicate with each other. With the absence of a central administration and their dynamic topologies, MANETs are vulnerable to many attacks, the most serious of which is Denial of Service attacks (DoS). A DoS attack prevents legitimate users from accessing services and resources, thus considerably degrading the performance of the network. Several schemes have been posited to detect and respond to this attack in MANETs, such as distributed firewalls, filtering and so on. This paper presents a novel approach MDR (Monitoring, Detection, and Rehabilitation) system which aims to detect and response to DoS attacks in MANETs. This method is based on a trust concept between nodes and isolates misbehaving nodes. Nodes need to cooperate with each other and exchange some information to calculate the trust value. Moreover, trust in this method is a temporal action and needs to be iteratively checked over time.

A Taxonomy of Defence Mechanisms to Mitigate DoS Attacks in MANETs

ملخص المشاركة:

In recent years MANETs (Mobile ad hoc Network) have had a large prevalence in many sectors. Due to their nature, MANETs have faced some challenges, especially with regard to security;- dynamic topology, power and bandwidth constraints and the absence of central administration make MANETs vulnerable to many attacks. DoS (Denial of Service) attacks are a major problem for the network. These attacks deplete resources and greatly degrade network performance. In this paper, a taxonomy of the defence mechanisms is identified and their advantages and disadvantages are discussed. As posited in this paper, this taxonomy provides the basis for the development of an approach to detect DoS attacks in MANETs.

A survey of the mitigation methods against DoS attacks on MANETs

ملخص المشاركة:

In recent years, the mobile ad hoc network (MANET) has spread to many sectors, such as education and the military. A MANET is a self-configuring and spontaneous network that is established without any administrative management and without fixed infrastructure. Due to its nature, a MANET becomes vulnerable to many attacks, and in particular, Denial of Service (DoS). DoS overwhelm the network and deprive legitimate users from using network resources. There are many methods to mitigate this attack, such as firewalls, intrusion detection systems and filtering. Each defence method has some benefits and limitations. In this paper, a description of the components of an ideal system to mitigate DoS attacks is presented which will help to design a new method to detect this attack with certainty in MANETs.

Using Trust Based Method To Detect Dos Attack In Manets

ملخص المشاركة:

A MANET (Mobile Ad Hoc Network) is a group of nodes that communicate with each other via a wireless shared medium. Each node in a MANET behaves as a router and a host, so they can communicate with each other separately without needing to have an access point, and receive and forward packets to another node. Nowadays, the usage of MANETs has grown in different areas such as conference meetings, virtual classrooms, the military, rescue systems, voting systems and many more [1]. The prevalence of MANETs is due to a number of reasons, such as ease of installation, lack of fixed infrastructure required, and support for heterogeneous devices. However, the nature of MANETs has made them vulnerable to many attacks. For example, the absence of an administrative point and their dynamic topology have made MANETs vulnerable attacks such as Denial of Service (DoS) attack [2].

A DoS attack has serious ramifications to MANETs. It paralyses the network by preventing legitimate users from using the network resources, thus affecting availability. Such an attack degrades the performance of the network to legitimate users and may result in financial harm or degradation of services and resources [3-5].

Recent research has posited a variety of methods to detect and respond to this type of attack. These can be grouped into general approaches and attack-specific approaches. General approaches include firewalls, filtering, IDS (Intrusion Detection System), Watchdog, Pathrater, Pushback and Traceback. Other specific approaches, include reputation-based incentive mechanisms, trust management, DiDDeM and using routing protocols. These have had considerable success in detecting and responding to this type of attack [6-9].

This study proposes a novel trust-based approach to detect and respond to this type of attack. This system aims to detect misbehaving nodes and isolate them for a specific time. The methodology and system assumptions will be explained briefly.

Comparison of the MrDR method against different DoS attacks in MANETs

ملخص المشاركة:

A Mobile Ad-hoc Network (MANET) has special characteristics such as dynamic topology, the absence of an administrative point and no fixed infrastructure. These features make it vulnerable to many attacks, such as the Denial of Service (DoS) attack. This type of attack deprives users of access to their legitimate services leading to degradation of the network. This paper posits the Monitor, Detect, Rehabilitate (MrDR) method, which is applied to detect three types of DoS attacks: wormhole; greyhole; and jellyfish attacks is an effective mechanism for dealing with them. The Network Simulator (NS2) was used to test the efficiency of the MrDR method and the results show that it works better for greyhole attacks than wormhole attacks, and it works least well in the case of jellyfish attacks.

Detect DoS Attack Using MrDR Method in Merging Two MANETs

ملخص المشاركة:

Mobile Ad hoc Network (MANET) consists of a group of mobile nodes that can move abruptly in and out the network. MANET has several special specifications including; non-fixed infrastructure; the absence of a central administration; limited bandwidth; and limited energy. Merging two MANETs is a situation that can occur frequently because of mobility. Due to the nature of MANET, it is vulnerable to attacks such as Denial of Service (DoS). In this paper a proposed method called Merging Using MrDR (MUMrDR) is used to merge two MANETs based on the Monitoring, Detection, and Rehabilitation (MrDR) method to mitigate such attacks. By adopting this method, it will be possible to detect DoS attacks when merging two MANETs, thereby maintaining network operations
