Hybrid Routing Protocol

This chapter describes a hybrid routing protocol for mobile ad hoc network based on the packet relaying cooperation and zone-based network architecture. In each zone, a specific node called Principal manages the routing processing. The Principal receives, periodically from its zone‘s nodes, two values that express their rate of success and their rate of cooperation, and then calculates the average rate of success, and the average rate of cooperation of the zone. After what, it retransmits these averages to all nodes. The nodes use the two averages values to define the action to be undertaken, cooperate or not. The Principal, knowing the topology of its zone, receives route requests and calculates the path between the source and the destination according to the best way based on cooperation. The Principal‘s features are so that it is simple to realize. It does not impose constraints and it allows the information gathering that is necessary for the model solution. Such the routing protocol and the nodes (to undertake the actions that make them possible to cooperate) use this information. Simulations show the efficiency of the protocol opposite to the pro-active and reactive protocols in the context of cooperation in mobile ad hoc networks.

Mobile Ad Hoc Network (MANET) is a collection of communication devices or nodes that wish to communicate without any fixed infrastructure. The nodes in MANET themselves are responsible for dynamically discovering other nodes to communicate. A number of challenges like open peer-to-peer network architecture, stringent resource constraints, shared wireless medium, dynamic network topology etc. are posed in MANET. In this research, we identify the existent security threats an ad hoc network faces, the security services required to be achieved and the countermeasures for attacks in each layer. To accomplish our goal, we have done literature survey in gathering information related to various types of attacks and solutions, as well as we have made comparative study to address the threats in different layers. Finally, we have identified the challenges and proposed solutions to overcome them. There is no general algorithm that suits well against the most commonly known attacks such as wormhole, rushing attack, etc.

In a mobile ad hoc network, a source node must rely on intermediate nodes to forward its packets along multi-hop routes to the destination node. The performance of a mobile ad hoc network is closely related to the capability of the implemented routing protocol to adapt itself to unpredictable changes of topology network and link status. One of these routing protocols is optimized link state routing protocol which assumes that all nodes are trusted. However, in a hostile environment, the OLSR is known to be vulnerable to various kinds of malicious attacks. Without having any control on packet forwarding, an intermediate node can behave selfishly or maliciously to drop packets going through it. Therefore, in this article, the authors propose a new technique for the selection of multipoint relays whose aims to provide each node the ability to select alternative paths in order to reach any destination two hops away.

Now a day’s mobile ad-hoc network (MANET) is engaged by numerous scientists and endeavoring to be conveyed by and by. To accomplish this objective, these two components are a significant issue that we need to consider. The first is "overhead". As it were, messages that is not important to be sent when setting up a system association between versatile hubs. The following issue is the parcel sending rate from source to the goal hub that sufficiently high to ensure a successful system association. This paper is concentrating on improving the exhibition of the Location-Aided Routing Protocol (LAR) regarding overhead decrease by adjusting the calculation of the MANET course disclosure process. The consequence of the reproduction shows that the proposed convention can decrease overhead definitely, growing system lifetime and increment parcel sending rate while contrasting and other traditional conventions.

Secured communication in mobile ad hoc network is a crucial issue due to dynamic nature of the network topology. Due to lack of centralized control, issuing certificates from a centralized certification agent is not possible in ad hoc network. The major problem in providing security services in such infrastructure-less networks is how to manage the cryptographic keys that are needed. In MANET any node may compromise the packet routing functionality by disrupting the route discovery process. These unique characteristics of mobile ad hoc networks such as open network architecture, shared wireless medium, stringent resource constraints and highly dynamic topology cause a number of nontrivial challenges to security design. These challenges make a cause for building multi-fence security solution that achieves both extensive protection and desirable network performance. In particular, the absence of a central authorization facility in an open and distributed communication environment is a major challenge, especially due to the need for cooperative network operation. We propose a novel cluster based security scheme to protect mobile ad hoc network link layer and network layer operations of delivering packet over the multihop wireless channel. The dynamic network topology can be managed efficiently by the proposed cluster based architecture. A well-behaving node becomes a cluster member after the initial trust verification process. The membership validity period of a node depends on how long it has stayed and behaved well. Non-overlapping clusters are created using the dynamic cluster creation algorithm. The cluster construction is fully distributed so efficiency is not degraded by node mobility.

Mobile ad-hoc networks (MANETS) are infrastructure less networks and the topology of this network is always changing. The nodes can enter and leave the network at any time. These networks require a high security in communication, as its application demands so. Effective key management is the only technique, which can implement to secure the nodes in communication. In adhocnetworks there is no central controller or router such as in wired network. This will make this network more vulnerable to attack. The intruders can easily enter the net-work and can manipulate the contents easily. Traditional key management schemes will not fit for this type of networks. This article, discuss various key management schemes based on routing protocols in mobile ad-hoc network (MANET). It also analyses them in terms of the security and applicability.
