Mobile Ad Hoc

A mobile ad-hoc network (MANET) is an infrastructure-less network of wireless nodes. The network topology may change quickly with respect to time, due to node mobility. The network is a disintegrated network, activities such as delivering messages by determining the topology essential to be implemented by the nodes themselves i.e., the routing activity will be unified into mobile nodes. Due to the lack of centralized administration in multihop routing and open environment, MANET’s are susceptible to attacks by compromised nodes; hence, to provide security also energy efficiency is a crucial issue. So as to decrease the hazards of malicious nodes and resolve energy consumption issues, a simple confidence-based protocol is built to evaluate neighbor’s behaviour using forwarding factors. The reactive Ad-hoc on-demand multipath distance vector routing protocol (AOMDV), is extended and confidence-based Ad-hoc on-demand distance vector (CBAOMDV) protocol, is implemented for MANET. This implemented protocol is able to find multiple routes in one route discovery. These routes are calculated by confidence values and hop counts. From there, the shortest path is selected which fulfills the requirements of data packets for reliability on confidence. Several experimentations have been directed to relate AOMDV and CBAOMDV protocols and the outcomes show that CBAOMDV advances throughput, packet delivery ratio, normalized routing load, and average energy consumption.

Video streaming is content sent in compressed form over the netwoks and viwed the users progressively. The transmission of video with the end goal that it can be prepared as consistent and nonstop stream. The point is that to give client support to client at anyplace and at whatever time. Mobile Ad hoc Networks (MANETs) are considered an attractive nertwork for information transmission in many applications where the customer programme can begin showing the information before the whole record has been transmitted. Ad hoc On-demand Distance Vector (AODV) protocol is considered as one of the most important routing protocols in MANET. However, routing protocols assume a crucial part in transmission of information over the network. This paper investigates the performance of AODV Routing Protocol under video traffic over PHY IEEE 802.11g. The protocol model was developed in OPNET. Different outcomes from simulation based models are analyzed and appropriate reasons are also discussed. A different scenarios of video streaming were used. The metric in terms of throughput, end to end delay, packet delivery ratio and routing overhead were measured. A comparision with GRP and GRP are also reported.

Existing local route repair schemes such as localized route repair (LRR), ad hoc on-demand distance vector-backup routing (AODV-BR), and witness-aided routing (WAR) can be incorporated with reactive routing protocols to repair route breakages on ongoing routes. All of these schemes have some problems in local route repairing such as long delay, excessive energy consumption etc. To mitigate these problems in existing local route repair schemes, quick local repair scheme using adaptive promiscuous mode (QLRS-APM) is proposed. QLRS-APM is a novel approach in local route repairing but sometimes generates unnecessarily route error to the source. This paper provides a solution by giving an extension on QLRS-APM to avoid initiating route error messages to the source and also at the same time reducing excessive energy consumption from the network.

MANETs are a trending topic in the wireless communication network. MANETs are formed automatically by an autonomous system of mobile nodes that are connected via wireless links. Cluster-head gateway switch routing protocol (CGSR) is a proactive protocol which is also called table-driven protocol. It consists of routing table information before setting up a connection. Ad-hoc on-demand distance vector protocol (AODV) is a reactive protocol, it sets path only when demanded by the network. CGSR protocol forms a group of nodes into clusters and selects a node as cluster-head based on some clustering algorithms for each cluster. In this paper, we have proposed a protocol, which combines the advantages of both CGSR and AODV to minimize traffic congestion in an ad-hoc wireless network. The performance metrics such as routing overhead, end-end delay, packet delivery ratio, throughput, and average energy consumption are enhanced and compared with other clustering protocols such as CGSR and LEACH protocols. The comparison result reveals that the routing overhead, end-end delay, and the average energy consumption is reduced and packet delivery ratio, throughput is improved.

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.
