A mobile ad-hoc network is a collection of wireless mobile nodes which temporarily forms a network without any type of centralized administration which is already in use. In adhoc network, the battery lifetime of the mobile nodes is less. If suppose any nodes battery power is drained it leads to spreading of many divisions in the networks. Hence these spreader nodes are the very important spot in this network. For the purpose of data forwarding some very important nodes can drain their battery power in advance because of increase in load and processing for forwarding the data. Because of the variance in loads developed, the network of nodes will be collapsed very badly, the route lifetime will be reduced, network will be partitioned and route reliability is reduced in MANETs. Because of this, the most important criteria which have to be improved is the consumption of energy in mobile ad-hoc networks. The very important technique is power aware routing technique in MANETs. Hence minimization of energy in the network of mobile nodes individually can be done by using some of the routing techniques. The most important thing is to study the power aware protocol in order to help the new research doers and application developers to find a new idea for designing more efficient routing protocols.

A Mobile Ad hoc NETwork (MANET) is a self-organizing, infrastructure-less network of mobile nodes connecting by wireless links. In operation, the nodes of MANETs do not have a central control mechanism. It is known for its properties of routable network, where each node acts as a router to forward packets to other specific nodes in the network. The unique properties of MANET have made it useful for large number of applications and led to a number of security challenges. Security in the mobile ad hoc network is a very critical job and requires the consideration of different security issues on all the layers of communication. The countermeasures are the functions that reduce or eliminate security vulnerabilities and attacks. This chapter provides a comprehensive study of all prominent attacks in Mobile Ad Hoc Networks described in the literature. It also provides various proactive and reactive approaches proposed to secure the MANETs. Moreover, it also points to areas of research that need to be investigated in the future.

Mobile Ad Hoc Network (MANET) is the one of the type of ad hoc network, the MANET is a collection of two or more devices or nodes or terminals with wireless communications and networking capability that communicate with each other without the aid of any centralized  administrator also the wireless nodes that can dynamically form a network to exchange information without using any existing fixed network infrastructure. And it's an autonomous system in which mobile hosts connected by wireless links are free to be dynamically and sometime act as routers at the same time, In MANET, the mobile nodes require to forward packets for each other to enable communication among nodes outside of transmission  range. The nodes in the network are free to move independently in any direction, leave and join the network arbitrarily. Thus a node experiences changes in its link states regularly with other devices. Eventually, the mobility in the ad hoc network, change of link states and other properties of  wireless transmission such as attenuation, multipath propagation, interference etc. This paper discuses   study of Mobile ad-hoc Networks (MANET): classification, characteristics, structure of  MANET  and challenges that are imposed by Mobile ad-hoc Networks.

A mobile ad hoc network (MANET) is defined as a set of mobile nodes which communicate through wireless links with no central infrastructure. In these networks nodes are always moving and could enter to or exit from the network at any time. Therefore, network topology is completely dynamic. Another characteristic of these networks is the low node energy level, resulting from inherent node limitations. Stable routing is one method to face routing challenges in mobile ad hoc networks. The objective of this study is to stabilize TORA protocol which is a distributed routing protocol, with high adaptation, efficiency, and suitability for large and dense mobile ad hoc networks and thus to provide a new high efficiency protocol. The proposed protocol introduced as Stable-TORA has been compared with base protocol TORA in different scenarios via NS-2 simulator environment and its efficiency is evaluated.

Mobile ad hoc network is a network comprised of mobile nodes quickly forming an autonomous network for a particular purpose such as emergency search and rescue. One of the most prominent security challenges for such a network is the limited capacity in the mobile nodes, thereby preventing costly computation operations. However, this limitation on a mobile node manifests itself only when the mobile node is dispatched on an active duty (i.e., online). One can prepare the mobile nodes as much as possible offline in anticipation of an upcoming deployment. In this chapter, the authors present three offline/online authentication and key agreement schemes and one offline/online non-repudiation scheme, all aiming at fast online computation for mobile nodes in mobile ad hoc networks.

Route Recovery

The mobile ad-hoc network is the decentralized type of network in which mobile nodes can move from one location to another. Due to random mobility of the mobile nodes route establishment, route maintenance is the major issues of mobile ad-hoc networks. This research paper, focus on the route establishment and route maintenance properties of mobile ad-hoc network. The DCFR protocol is the route establishment and route maintenance protocol in which broker route will be recovered on the basis of node connectivity. The node, which has maximum connectivity, is selected as the best node for route recovery in DCFR Protocol. In this research work, the DCFR protocol is further improved by adding buffer size parameter for route recovery which also maintains quality of service in the network. The proposed DCFR protocol simulation results perform well as compared to existing DCFR protocol in terms of certain parameters

Hoc Networks

Consider a mobile ad hoc network where the nodes belong to different authorities. The nodes must be given incentives to spend their resources (battery power and transmission bandwidth) in forwarding packets that originate at nodes belonging to another authority.  This can be done by assigning a credit balance to each node: when a node acts as an originating node it uses its credits to pay for the costs of sending its own traffic; when a node acts as a transit node it earns credits by forwarding traffic from other nodes.This paper presents a credit-based incentive scheme which assists nodes when they lack the credits necessary to transmit their data. An essential part of the credit-based scheme is a decentralised credit redistribution mechanism to destroy (create) credit at nodes that are over (under) supplied with credit.The goal of this paper is to investigate the effect of various fraudulent activities on the performance of the credit-based incentive scheme. We show that the credit-based scheme is inherently robust with respect to a number of fraudulent activities, provided the nodes behave in a rational manner. We show that credit redistribution is the main reason why the credit-based incentive scheme is relatively immune to fraud.

A mobile ad-hoc network is a method of communication between different nodes (mobile devices) without the use of base stations, which are used in wired networks. In a Mobile ad-hoc network, nodes can play the role of a receiver, sender, or a relay. As movement is flexible in Mobile ad-hoc networks and nodes have limited resources, nodes may join the communication or exit it at any time. Therefore, for Mobile ad-hoc networks, routing techniques - selecting communication routes and maintaining them – is considered important in an environment of constantly changing network topology. To overcome this problem, this paper proposes a reliable routing protocol based on MP-AOMDV, which monitors changes in signal strength not only for GPS signals but reception signals as well. Although MP-AOMDV was researched under the assumption of fixed movement direction and speed, this paper proposes a routing technique that works with changing movement direction or speed of nodes.

Wireless technology has brought a very advanced change in the field of the internet. It has given rise to many new applications. In recent years, a lot of work has been done in the field of Mobile Ad hoc Networks (MANET) which makes it so popular in the area of research work. MANET is an infrastructure-less, dynamic network that consists of a collection of wireless mobile nodes, and the communication between these nodes has been carried out without any centralized authority. There are several network performance metrics, Packet Loss and End-to-End Delay which can be taken into account, for getting a general idea about the performance of the Geographical Routing Protocol in Mobile Ad-Hoc Networks. The proposed research will evaluate the parameters which affect the communication in the Geographical Routing Protocol in Mobile Ad-Hoc Networks.

The growth of laptop and 802.11/Wi-Fi wireless networking have made Mobile Ad hoc NETworks (MANETs) a popular research topic since the mid to late 1990s. Many academic papers evaluate protocols and abilities assuming varying degrees of mobility within a bounded space, usually with all nodes within a few hops of each other and usually with nodes sending data at a constant rate. Different protocols are then evaluated based on the packet drop rate, the overhead introduced by the routing protocols, and other measures. Research in MANET is like playing in a vast playground with only few known rules and large number of unknown rules applied to its different areas. Some areas are still unknown and some areas are at its early stage. Some of the research challenges that MANET present are dynamic topologies, battery lifetime, disconnected operations, security, et cetera. In general there are three types of MANET: vehicular ad hoc networks, intelligent vehicular ad hoc network, and Internet based mobile ad hoc networks. Each of these three types has its own research areas.
