Technical advancements in wireless technology and portable devices leading to new features in wireless communication networks, mobile ad hoc networks (MANETs) are a kind of them. MANETs are, containing autonomous mobile nodes (nodes with special abilities) a class of multihop wireless networks where two distant nodes can communicate with each other without a centralized administration or an underlying network infrastructure. Networks having such features find applications like where there is a need for an instantaneous temporary network to handle emergency situations. On the other hand, being dynamic networks with time to timevarying topologies MANETs are placing the challenges in routing the data packets in the network. This paper presents an extensive simulation work done on the most prominent ondemand routing protocol i.e., ad hoc on demand distance vector routing protocol (AODV) is for a set of performance evaluation parameters by varying a set of various network parameters.

Integrating the Mobile Ad-Hoc Network (MANET) with Internet has many advantages. The Data collected from the Mobile nodes can be broadcasted to the world by connecting the Internet to it via Gateway. Clustering is a practical way to enhance the system performance. Security is a significant issue in the Integrated MANETInternet climate in light of the fact that in this climate we need to think about the assaults on Internet availability. So, to overcome this issue, we have proposed Secure and Authenticated routing protocol (SARP) to enhance security performance of the networks. This routing protocol is used to discover a secure route and to transmit data packets securely. In this protocol clusters are formed and security relies on the hardness of the symmetric and asymmetric key algorithms. We show the practicality of this convention as for the security prerequisites and security investigation against different assaults. The estimations and reproductions are given to show the security of the proposed convention. The outcomes show that, the proposed convention have preferred execution over the current secure conventions for Cluster based Internet Integrated with MANETs, in terms of security.

A mobile ad hoc network (MANET) is a combination of multiple mobile nodes, which are interconnected by radio link. In MANET, sensor nodes are free to move, and each node can act as a host or router. Routing is one of the most challenging tasks because nodes move frequently. Therefore, in MANET, the routing protocol plays an important role in selecting the best route to efficiently transmit data from the source node to the destination node. In this paper, the best path with efficient Ad Hoc on Demand Distance Vector (AODV) routing protocol is chosen as the routing mechanism. The properties of each node are categorized using firefly algorithm. The Artificial Neural Network (ANN) is trained as per these properties and hence in case if the gray hole node is detected within the route, it is identified and the route between the source and the destination is changed. At last, to show how effectively the proposed AODV with Firefly and ANN works is computed in terms of performance parameters. The throughput and PDR is increased by 4.13 % and 3.15 % compared to the network which is affected by gray hole attack. The energy up to 44.02 % has been saved.

Pervasive computing has wide application in military, medical and smart home domain. In pervasive computing, a large number of smart objects interact with one another without the user intervention. Although the technology is promising but security needs to be addressed before the technology is widely deployed. Pervasive networks are formed spontaneously and the devices communicate via radio. Thus, mobile ad hoc networking is an essential technology for pervasive computing. An ad hoc network is a collection of wireless mobile nodes, which acts as a host as well as a router. The communication between the nodes is multihop without any centralized administration. AODV (Ad Hoc On demand Distance Vector) is a prominent on-demand reactive routing protocol for mobile ad hoc networks. But in existing AODV, there is no security provision against well-known attack known as “Black hole attack”. Black hole nodes are those malicious nodes that agree to forward the packets to destination but do not forward the packets intentionally. Thischapter extends the watchdog mechanism for the AODV routing protocol to detect such misbehavior based on promiscuous listening. The proposed method first detects a black hole node and then gives a new route bypassing this node. The experimental results show that in a lightly loaded, hostile environment, the proposed scheme improves the throughput compared to an unprotected AODV protocol.

Mobile ad hoc network is an assembly of mobile nodes with no centralized server. Due to mobility of nodes and decentralized network it is difficult to maintain the quality of service (QoS) in routing the packets from source to destination.  QoS can be defined in terms of various metrics like delay, bandwidth, packet loss, routing overhead, jitter. Routing can be unicast, multicast or multipath.  This paper presents the description about the QoS multipath routing algorithm.

Mobile ad hoc network (MANET) attracted various researchers in the emerging communication networks without having any centralized structure. In this network, mobile nodes moves in their own wish creating a dynamic topology. Routing is a cumbersome task with this dynamic topology from time to time change in connection pattern. DYMO is emerged as challenging protocol in MANET but works on static configuration parameters such as Hello messages. The mobile device updates the connectivity of their neighbours by sending Hello messages at frequent intervals irrespective of the network scope (terrain) and network elements(number of nodes). As the mobile nodes are battery equipped devices, lot of energy is consumed with these messages. Energy efficient mechanisms are necessary in this type of networks. In this work, DYMOHBFLWTN mechanism is proposed to set the Hello parameter dynamically in DYMO considering network terrain and number of nodes utilizing fuzzy principles. Experiments are conducted on Qualnet 7.0 simulator to evaluate mechanisms - DYMOHBFLWTN and DYMO. The proposed DYMOHBFLWTN mechanism provides better results compared to existing DYMO.

Mobile Ad Hoc

A mobile ad hoc network is a collection of mobile nodes communicating without wired network and infrastructure or centralized control. Due to limited transmission range of wireless network, more than single hops may be required to transfer data across the network. In order to reliable communication within the network, a routing protocol is used which are call MANET routing protocol. The major function of such an MANET routing protocol is to establishment short and real route between a pair of nodes so that messages may be delivered in a timely manner. This chapter examines two routing protocols for mobile ad hoc networks– the Destination Sequenced Distance Vector (DSDV), the pro-active routing protocol, and the Ad hoc On- Demand Distance Vector routing (AODV), an re-active routing protocol. The authors compare both protocols based on packet delivery fraction and average delay with changing number of source nodes and pause time.

The Comparative Study

In modern era, MANET i.e., Mobile Ad-hoc Network is a very powerful, interactive tool and useful resource for transmission/communication in computer networks. About composition of MANET, a collection of mobile nodes have the potential of creating self-maintaining and self-configurable network without having any centralized infrastructure i.e., MANET is a self-organized network without any infrastructure. Nodes in the network require energy for transmission of data after collapse of energy a node become inactive and it can’t participate in the communication. Due to exhaustation of energy the network becomes unstable. An unstable network requires extra routing process for coin out a route. In future security of MANET is a major challenge for smooth and efficient data communication. There are many protocols in MANET but in this paper, we discussed AODV routing protocol for data communication. In this paper a new algorithm is designed i.e., modified AODV with security constraint. This paper also gives the comparative study of original AODV and modified AODV.

Mobile Ad-hoc NETworks (MANETs) are defined as a collection of mobile nodes that cooperate in order to operate. Nodes in MANETs should build and maintain routes in order to communicate. A routing algorithm is used to manage these routes. MANETs have dynamic topology because of node mobility. The probability of route failure increases when intermediate nodes have higher mobility. This study will propose a routing protocol that depends on the failure history of the nodes from which the route will constructed. The proposed protocol will be implemented over the existing Ad hoc On-Demand Distance Vector (AODV) routing protocol. It is expected that the proposed protocol will improve the packet delivery ratio in the network.

Mobile ad-hoc Network (MANET) is a multihop wireless network that a many collection of mobile nodes that are dynamic. MANET each node on the network have the same position, so it needs the appropriate routing protocol, to support the exchange of data to be optimal. In this study, the routing protocol to be tested is AODV and BATMAN based scenario increasing the number of connections, nodes and speed. Simulation parameter scenarios is number connection 1 UDP, 2 UDP, 3 UDP, and number of node 25 node, 50 node, 100 node, and then number node speed 20 m/s, 50 m/s. in this AODV routing protocol will establish a rute from the source node to the destination only if there is a request from the source node. BATMAN routing protocols, all decisions and information disseminated throughout the node and will regularly update on each node. The performance parameters to be measured such as delay by using OMNET ++ 4.6. Output of simulation will analysis with two way anova and multivariate to know correlation between variation scenario impact to delay. The results obtained in this study AODV and BATMAN have their respective advantages, analisys with two-way anova show that both AODV and BATMAN get the impact of the scenario from incrising the number of connections, the number of nodes and the number of nodes speed with a p-value of 0.012212 (<0.05) with two-way anova. From all scenarios, the number of UDP connections has the greatest impact, from UDP 1, UDP 2 and UDP 3. Followed by the number of speed 50 and node 100. So it can be concluded that the connection has an effect on increasing delay. The increasing number of speed and nodes can contribute to an increase in delay if number of nodes above 100 and speed above 50. With multivariate analysis, the BATMAN protocol had the most impact on the delay under the scenario then AODV.
