With the advancement of wireless technologies, Mobile Ad hoc NETwork (MANET) has been an important field of study. MANETs find useful applications in the real world, for example in military battlefield and disaster management. Since MANET is dynamic in nature, it must be represented by dynamic graph. Evolving graph, a form of dynamic graph, may be used for the purpose. When we talk about a network, a routing protocol comes into the question, and one of the most popular routing protocols is AODV. However, since AODV suffers from a drawback that it may be a victim of black hole attack, we need to find a technique to eliminate the possibility of the phenomenon. This paper makes a study of MANET and an efficient way of representing MANET by dynamic graph. It explains the AODV routing technique and the black hole attack. It then extends the idea of dynamic graph to propose a technique to solve the problem of black hole attack in AODV.

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.

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 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

Mobile Ad Hoc Network is an infrastructure less wireless network where the mobile nodes leaves and joins the mobile network very frequently. The routing of the packets from source node to destination node, the routing protocol is used. On Demand Distance Vector Routing protocol is very common and implemented with Mobile Ad Hoc Network nodes to handle the operations of packet routing from by any node as a source node to destination node. In this paper prevention of black hole attack by modifying the On Demand Distance Vector routing protocol. The sequence number of 32 bit is initiated with the Route Reply and route sequence packet broadcast to determine the request reply from black hole node under the Mobile Ad Hoc Network. The sequence number and On demand Distance Vector Routing protocol are integrated with a mechanism to find the Request Reply of message containing routing information from source to destination node in Mobile Ad Hoc Network.
