The Mobile Ad Hoc Networks Essay

An attack is any malicious or accidental disruption in the confidentially, integrity, or availability of information and network resources. Attacks can come from many places, electronic, physical, or human. Electronics attacks may come from the external network (Internet) or the internal network (Intranet); physical attacks can come in the form of hardware and equipment sabotage or theft, and human attacks most often come in the form of social engineering. Some of the attacks identify and evaluate in this paper are: spoofing, replays attacks, access attack suppress-relay, and source and repudiation attack.

The most popular and dangerous type of attack that happens mostly these days, within the contemporary electronic society, is the distributed denial of service attack (Nemati 2009, 45). This technique is usually defined as specific attacks from multiple wireless sensor networks ends, towards a set of authentic nodes (Malin et al. 2015, 76). Its main intention is exhausting their entire resources. Denial and deception techniques take various forms, most of which depends on the attacker’s objectives and the target system. However, they all have a similar objective, which is attacking the enemy. These assaults tend to influence the system's execution fundamentally consequently bringing about an entire system operation loss of motion (Johnson

Although, there is one of the vulnerabilities that is pretty much impossible to guard against, DoS like Molta points out, “Other problems are looming, the most pernicious of which are DoS (denial of service) attacks. While DoS is a fact of life on all networks, it's worse on wireless networks because not only do you need to guard against attacks at Layer 2 and above, you're also extremely vulnerable to physical-layer attacks to the medium” (Molta, 2002, p. 18). In this essay, some vulnerabilities will be looked at that can affect Wi-Fi home users as well as businesses that implement wireless networks because both types of networks can be affected by the same types of intrusion or disruption attacks. Even though this paper is about vulnerabilities, it is important to point out that wi-fi networks can still be operated safely with a high level of security in place.

Wireless technology has become an increasingly crucial part of today's world. From health care and retail to academia across the world, wireless systems are improving the rate and ease with which data is sent and received. Two specific examples of the wireless technology used today personally and professionally are local area networks (LAN) and personal area networks (PAN).

Designing a foolproof security for ad hoc network is a challenging task due to its unique characteristics such as, lack of central authority, frequent topology changes, rapid node mobility, shared radio channel and limited availability of resources

Abstract— this paper is an involvement in the field of security study on mobile ad-hoc networks. Boundaries of the mobile ad hoc nodes have been considered in order to design a secure Ad hoc routing protocol that thwarts selfish and flooding attacks. We took the base of Ad hoc On Demand Routing Protocol (AODV); the most popular Routing protocol. The significance of the proposed protocol that should make sure security as wanted by providing a broad architecture of Trusted and PES Mechanism based smart Path Routing protocol (TBAODV) based on effective key management, secure neighbor detection, secure routing data’s, finding malicious nodes, and eliminating these nodes from routing table. Our results clearly show that our secured Ad hoc routing protocol increases the throughput and packet delivery ratio while it has a tolerable increase in the routing overhead and average delay. Also, security study proves in details that the proposed protocol is robust enough to thwart all classes of

Mobile ad-hoc networks (MANET) are characterized as networks without any physical connections. In these networks there is no fixed topology due to the mobility of nodes, interference, multipath propagation and path loss. Hence a dynamic routing protocol is needed for these networks to function properly. Many Routing protocols have been developed for accomplishing this task. MANET routing protocols can be categorized as Proactive or Table-driven Routing Protocols Reactive or On Demand routing protocols and Hybrid routing protocols. This paper presents the three types of routing protocols in MANET and makes a comparative discussion of the features of each type of that routing protocol.

Abstract— Mobile Ad hoc Network (MANET) is a special self-describing wireless ad hoc network which consists of more number of nodes that can move randomly and erratically. Because of this infrastructure it enables many kinds of attacks and establish topology-exposure problem. Many of the existing multipath protocols may ignore the topology-exposure problem. In this, we proposed a TOpology-HIding multipath routing Protocol (TOHIP) for preventing attacks in topology-exposure. In TOHIP, the link connection information is hidden in route messages, so that the malicious nodes cannot conclude the network topology. In Route Reply phase, the protocol TOHIP can also be used to establish multiple node-disjoint routes and eliminate the unreliable route before transmitting packets in Route Probe phase. With the help of a newly designed protocol, security was assured and earned better capability of finding routes in MANET. The simulation result shows that TOHIP has given better performance when compared with Ad hoc On-demand Multipath Distance Vector (AOMDV) routing protocol.

Flooding attack is one such kind of DoS attack, at interval that a compromised node floods the entire network by inflicting associate in nursing large of faux RREQs to nonexistent nodes at interval the network, thus resulting in network congestion. Throughout this paper, the protection of painter AODV routing protocol is investigated by distinctive the impact of flooding attack on it. A simulation study of the implication of flooding attack on the performance of the AODV routing protocol is presented. The simulation surroundings is implemented by using the NS-3 network machine. it's determined that as a result of the presence of such malicious nodes, average proportion of packet loss at interval the network, average routing overhead and average system of measurement demand - all can increase, thus degrading the performance of painter significantly.

Before the age of digital mobile networks, all cell phones broadcast analog signals. This intended using the Advanced Mobile Phone System (AMPS) standard, which runs in a range of frequencies between 824MHz and 894MHz, dubbed the 800MHz band.

Abstract— this paper is an involvement in the field of security study on mobile ad-hoc networks. Boundaries of the mobile ad hoc nodes have been considered in order to design a secure Geographic routing protocol that thwarts selfish and flooding attacks. We took the base of Ad hoc On Demand Routing Protocol (AODV); the most popular Routing protocol. The significance of the proposed protocol that should make sure security as wanted by providing a broad architecture of Secured PPEM Mechanism based Multi-Hop Strong Path Geographic Routing protocol (SMHSP) based on effective key management, secure neighbor detection, secure routing data’s, finding malicious nodes, and eliminating these nodes from routing table. Our results clearly show that our secured Geographic routing protocol increases the throughput and packet delivery ratio while it has a tolerable increase in the routing overhead and average delay. Also, security study proves in details that the proposed protocol

A mobile Ad hoc network (MANET) is a collection of wireless mobile nodes self-configured to form an infra-structure less network. It is important that the routing protocol should be able to find routes that have a high degree of mobility. The challenges to the routing protocol design are the lack of dedicated routing infrastructure. Routing is the process of finding a path from a source to some arbitrary destination on the network. Existing routing protocols can be classified either as proactive or reactive. Routing in MANET is an important issue as it involves sending messages to a destination node in a network. As each node move arbitrarily in MANET, it cause

To accomplish availability and reliability network routing protocols should be prevailing compared to jamming attacks. The trustworthiness of distributing data packets from end to end using multi-hop intermediary nodes is a noteworthy problem in the mobile Adhoc network. Due to the intrinsically self-motivated nature of

Abstract—Mobile Ad-hoc Network (MANET) is a kind of wireless network. A Wireless ad-hoc network is a temporary network with no network infrastructure. The nodes communicate with each other, they co-operate by forwarding data packets to other nodes in the network. Thus the nodes find a path to the destination node using routing protocols. Due to the security vulnerabilities of the routing protocols, wireless ad-hoc networks are unprotected to attacks of the malicious nodes. One of these attacks is the Sinkhole Attack. Sinkhole attack is a kind of routing attack in MANET. A sinkhole node tries to attract all the network packets to it-self from all neighboring nodes. This paper focuses on to detect and prevent sinkhole node. By using a hybrid detection technique which combines the advantages of both reactive and proactive routing Protocol to detect the black hole

The detection techniques which make use of reactive routing protocols have low overheads, but have high packet loss problem. Therefore, using a hybrid detection technique which combines the advantages of
