Mobile Ad Hoc

Mobile Ad-hoc Network (MANET) is a dynamic wireless network without any infrastructures. The network is weak and vulnerable to many types of attacks. One of these attacks is BlackHole. In this attack, a malicious node advertises itself as having a high sequence number and a shortest path to a specific node to absorb packets. The effect of BlackHole attack on ad-hoc network using AODV as a routing protocol will be examined in this research. We also propose a new mechanism, called DPBA-AODV, to detect and prevent BlackHole attacks on AODV protocol. Simulation result, by using NS2, depicts the efficiency of our proposed mechanism in packet delivery ratio under the presence of BlackHole nodes.

Mobile Ad Hoc

Mobile ad hoc network (MANET) is one of the most widely used networks, which has attracted attentions, having features such as limited energy resources, limited bandwidth, and security weaknesses due to lack of a central infrastructure. Safe and suitable routing is one of the research aspects of MANET. In this paper, a proposed method, called M-AODV, which is a type of overhearing backup protocol, based on AODV, is presented. The simulation results of this protocol, applied by NS2 simulator, showed the improvement of packet delivery rate and reduction of overhead and delay. Moreover, to assess the security of the proposed protocol, we simulated M-AODV and AODV protocols under black hole and wormhole attacks, using no security solution. The results showed that M-AODV had been improved in terms of packet delivery ratio, and the delay had been reduced as well, but the amount of overhead had been increased.

Hybrid Protocols

The network in which the nodes can enter or leave the network as per their need is known as mobile ad-hoc network. This is a self-configuring type of network and so the routing in this type of network is very difficult. Numerous routing protocols are involved here which are classified on the basis of their properties into reactive, proactive and hybrid protocols. There are several important parameters such as delay, packet loss and throughput. These parameters are utilized for checking the performance of three routing protocols namely AODV, DSR and DSDV within this research. In comparison to the other protocols, the AODV routing protocol provides better results. In order to provide efficient path establishment from source to destination, enhancement has been proposed here within the AODV protocol which includes the utilization of cuckoo search and bee colony named bio-inspired techniques in it. The nodes that are found to be common in the selected paths are chosen to be the best nodes for the path. The NS2 tool is used for performing the simulations. As per the results achieved it can be seen that the AODV protocol provides better results in terms of the above mentioned parameters.

Mobile Ad Hoc

In order to effectively manage the communication nodes in Mobile Ad Hoc Network (MANET), it is important to know the topology of such networks. Traditional Ad-hoc On-demand Distance Vector (AODV) protocol can not get the MANET topology due to the lack of the topology discovery mechanism. Aiming at this problem, an enhanced topology discovery algorithm based on AODV (AODV-TD) is proposed. AODV-TD can not only obtain the topology of dynamic network by topology discovery request, but also realize route discovery among nodes. Finally, the proposed algorithm is implemented on a hardware platform using CC1100, and the experiment results show that, even the network changes dynamically, AODV-TD can still discover the network topology rapidly and accurately, so that contribute to reducing the route discovery time and the RREQ forwarding packets.

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.
