The security of the data which is transferred from source to destination is of prime importance in the mobile ad hoc network (MANET) or any kind of network to be very precise. If the data gets lost then the entire purpose of deploying and creating the network fails. Mobile ad hoc networks suffer from various attacks out of which black hole attack is considered the most dangerous one because in this attack the venomous node release all the packets received by it. The authors in EAODV has used the concept of fake route request packets to identify the black hole nodes in the grid. The proposed technique detects the malicious black hole node using the sequence numbers. The performance of the network has been examined based on end to end delay, packet delivery ratio, detection time, throughput and remaining energy. These parameters have shown improvement over the existing scheme.

A Mobile Ad hoc Network (MANET) is a collection of wireless nodes communicating over multi-hop paths without any infrastructure. Nodes must cooperate to provide necessary network functionalities. The security in routing protocols like Dynamic Source Routing (DSR) can be compromised by a “Black Hole” attack. Here, a malicious node claims to have the shortest path to the destination and attracts all traffic and drops them, leading to performance degradation. The situation becomes worse when two or more nodes cooperate and perform the “Cooperative black hole” attack. This chapter proposes a solution based on probing to identify and prevent such attacks. The proposed solution discovers a secure route between the source and destination by identifying and isolating the attacking nodes. Simulation results show that the protocol provides better security and performance in terms of detection time, packet delivery ratio, and false negative probability in comparison with trust and probe based schemes.

A Mobile Ad hoc Network (MANET) is a collection of wireless computers (nodes) communicating over multi-hop paths, without infrastructures such as base stations and access points. Nodes must cooperate to provide necessary network functionalities. The Dynamic Source Routing (DSR) protocol is a principal routing protocol in MANET, where security can be compromised by a “Black Hole” attack. In this attack, a malicious node claims to have the shortest path to the destination and attracts all traffic and drops all packets sent for forwarding, leading to performance degradation in the network. The situation becomes even more severe when two or more nodes cooperate and perform an attack called the “Cooperative Black Hole” attack. This article proposes a solution based on probing to identify and prevent such attacks. The proposed solution discovers a secure route between the source and destination by identifying and isolating both single and cooperative black holes, making the MANET resistant against such attacks. Simulation results show that the protocol provides better security and performance in terms of detection time, packet delivery ratio and false negative probability in comparison with trust and probe based schemes.

Creating dynamic communication infrastructures between mobile devices and satisfying the desires for time-sensitive multimedia applications have introduced new challenges in the design of protocols for mobile ad hoc networks. In this paper, to stream time-sensitive applications using mobile ad hoc network (MANET), we have selected the Optimal Link State Routing (OLSR) protocol. However, the protocol has high overhead because each node selects a set of multipoint relay (MPR) nodes. Therefore, we have proposed quality of service (QoS) supporting the MPR selection approach and a new lower maintenance clustering approach for minimizing the overhead of the network. As a result, the proposed approach showed a better result in the average end-to-end delay, packet delivery ratio, routing load, and throughput.

Security is a vital requirement in mobile ad hoc networks to provide secured communication among mobile nodes. Due to different characteristics of MANETS, it creates a number of consequential challenges to its security design. To overcome the challenges, there is a need to build a powerful security solution that achieves both broad protection and desirable network performance. Mobile Ad hoc Network (MANET) has emerged as a new leading edge of technology to provide communication wherever and whenever required. As the wired network needs established infrastructure for communication but the mobile ad hoc network does not need any infrastructure, centralized management and control. Due to movable nature of nodes in Mobilead hoc network difficult routing between nodes are not very easy task. For this purpose many reactive routing protocols have been implemented like AODV, DSR, and DSDV. In the first part of this work, we propose a new algorithm AODV-BTR to improve existing on demand routing protocol and an attempt has been made to compare the performance of proposed algorithm (AODV-BTR) with existing algorithm AODV. Ad hoc networks are susceptible to many types of attacks; due tomovable nature of nodes it is very difficult to provide security at each node. This paper introduces the black hole attack; in this type of attack mischievous node announce that he is having the shortest path to all nodes in the environment by sending fake route reply message. This paper proposes an easiest way to detect Black hole attacks using DLM technique. DML method presents the solution to detect & remove blackhole attack in reactive protocol called AODV-BTR.

Mobile ad hoc network (MANET) is a self-configuring network that is formed via wireless links by a collection of mobile nodes without the help of a fixed infrastructure or centralized management. Each mobile node can move freely in any direction, and changes their links to other devices frequently. Security is an essential part of ad hoc networks. Due to its dynamic topology, resource constraints, no centralized infrastructure and limited security, it is vulnerable to various attacks and black hole attack is one of them. In a black hole attack, a malicious node impersonates a destination node by sending a spoofed route reply packet to a source node that initiates a route discovery. By doing this, the malicious node can deprive the traffic from the source node. In order to prevent this kind of attack, it is crucial to detect the abnormality occurs during the attack. In conventional schemes, anomaly detection is achieved by defining the normal state from static training data. However, in mobile ad hoc networks where the network topology dynamically changes, such static training method could not be used efficiently.

Mobile Ad hoc network is a temporary network. It helps to communicate two or more devices for short range. Routing Protocols are use to establish a communication in MANET. As it is a open network , it has many vulnerabilities from security point. Black hole Attack is one of the major concern in MANET. In this paper, we have implemented Black hole Attack in random mobility environment and analyse its impact on MANET using various parameters for single and multiple connection in MANET. Black hole attack disturbs one of the connection in the network while remaining connection are unaffected. During our analysis, we found that performance result of black hole attack in multiple connection network give a similar kind of output mentioned in various research paper related to gray hole attack, which will make difficult to analysis the type of attack in the network.

Due to the dynamic nature of mobile ad hoc network (MANET), the quality of service (QoS) requires several improvements. The present papercomeswithin the framework of research to optimize QoS in MANET. In this paper, we propose a novel version of OLSR based on the clustering approach which is inspired from Lin and Chu heuristic and adapted to beimplemented inOLSR. We studied its stability and we compared its performances to those of standard OLSR. The metrics we used in evaluating network performances were average end-to-end delay, control routing overhead, and packet delivery ratio. Experimental results show that our alternative significantly reduces the traffic reserved to monitoring the network, which positively influences other performances such as throughput, delay, and loss.

Cluster Based Routing

Mobile ad hoc networks (MANETs) are wireless infrastructure-less network consisting collection of autonomous nodes that communicate with each other in decentralized manner. Security remains major challenge due to its some unique characteristics like open medium, mobility and hence topology changes. Therefore, routing protocol for MANETs is much vulnerable to attacks. Black Hole is a type of attack, where malicious node falsely advertises itself having the shortest or optimal path to the destination node. This attack is more dangerous while a group of nodes are cooperating with each other.The objective of this paper is to design cluster based routing protocol and prevent it from the black hole attack. The simulation results show improvement in packet delivery ratio and control overhead.
