In recent years, Mobile ad hoc networks ((MANETs) have generated great interest among researchers in their implementation under several computing environments. However, MANETs are highly susceptible to various security attacks due to their inherent characteristics. The ad hoc on demand distance vector (AODV) is most suitable routing protocol for mobile adhoc networks in which resource consumption attacks are frequent if it is not detected timely. In this paper, we have proposed a scheme to detect as well as overcome black hole attacks using an Intrusion Detection System (IDS). The proposed scheme is implemented using network simulator 2(NS2) to compare its performance against the standard AODV with and without attack. The results of the simulation show that proposed scheme optimizes the end-to-end delay, normalized routing load, packet delivery fraction and average throughput in comparison with AODV protocols under black hole attack.

Mobile Ad Hoc

Mobile Ad-hoc Network (MANET) is a kind of wireless network that has the most challenging network infrastructure. It is formed using the mobile nodes without any centralized administration from the security perspective and is a self-configuring fastest emerging wireless technology, each node on the MANET will act like a router which forwards the packets. Dynamic nature of this network makes routing protocols to play a prominent role in setting up efficient route among a pair of nodes. Dynamic Source Routing (DSR) and Ad-hoc On-Demand Distance Vector (ADOV) is a reactive MANET routing protocols. Most of the attacks on MANETs are routing protocol attacks. Attacks on routing protocols, especially internal attacks will cause the damage to MANETs. Sinkhole and black hole attacks are a type of internal attack which is affected by attempting to draw all network traffic to malicious nodes that fake routing update and degrade the performance of the network. The black hole nodes should be detected from the network as early as possible via detection mechanism and should also guarantee the higher detection rate and less cross-over error rate. In this paper, we studied the characteristics of black hole attack and how it will affect the performance of the distance vector routing on demand routing protocol such as (ADOV) protocol, which recognizes the presence of black hole node from packet flow information between nodes and isolates it from the network via applying AODV protocol that one of popular routing protocol. We have evaluated the performance of the system using widely used simulator NS2, results prove the effectiveness of our prevention and detection method.

Mobile Ad Hoc

Mobile Ad Hoc network is a self-composing network with a highly dynamic network topology. Although it has many advantages, there are still some safety problems in it. One of these problems is the black hole attack. The black hole attack is a typical attack to the Ad Hoc network and is also the main threat facing it. In this paper, the safety problems exist in the AODV protocol, which is a kind of routing protocol in the Ad Hoc, has been analyzed in detail. In the meanwhile, an improved Secure Ad Hoc On-Demand Distance Vector Routing called OSAODV has been proposed and realized based on the NS2. Finally, three set of experiments have been made, the results have shown that the OSADOV can avoid the black hole attack very well.

Mobile Ad Hoc Networks (MANET) are typically wireless networks that do not have any fixed network architecture. This makes the task of routing layers difficult. A popular reactive routing protocol – Ad hoc On-demand Distance Vector (AODV) used in MANETs has certain vulnerabilities which make it susceptible to black hole attacks. This paper proposes an innovative technique to detect and prevent the possibility of a black hole attack in AODV based MANETs. Using the approach of detecting multiple Route Reply (RREP) messages, authentication of nodes is done by the use of a randomly generated id unique to each route discovery process. This method was tested using simulations in NS2 software and compared with previous attempts. The proposed method showed marked improvement in performance in the presence of malicious nodes.

Better Than

Simulation environment of the mobile Ad Hoc network is built by applying NS2 simulation software. The simulation data indicates that AODV routing protocol is better than DSDV in throughput, fairness and stability. In the underwater network environment where the nodes are in Low-Speed movement, the data transfer rate of AODV routing protocol is higher than AOMDV. To a certain extent, AODV is more suitable for application in underwater environments.

Mobile ad hoc networks (MANETs) are collection of nodes connected through wireless medium and do not require infrastructure for operation. Network Topology keeps on changing because mobility of nodes are high. Therefore, it is important for MANETs to provide excellent routing and security features. Since MANETs do not require any pre-existing infrastructure, they are extensively used in emergency and rescue and military applications. MANETs thus will form essentially an important part in wireless networks. In this paper, Ad hoc On-Demand Distance Vector (AODV) and Greedy Perimeter Stateless Routing (GPSR) routing protocol performance is compared with respect to Throughput and E2ED and observed that there is an improvement in throughput by 11% in case of GPSR. Simulation is performed using NS3.

The limited battery energy is an important consideration in the effective operation of an Ad- hoc network. We propose a protocol named as Energy Saving Multi Directional Routing (ESMDR) that provides a lower energy cost effective routing solution. The performance evaluation of our protocol is carried out using a statistically collected data over Dynamic Source Routing (DSR) and Ad-Hoc On-Demand Distance Vector (AODV) protocol. Analysis exhibits a clear edge over the existing protocol.
