ABSTRACT

            An ad-hoc mobile network is a collection of mobile nodes that are dynamically and arbitrarily located in such a manner that the interconnections between nodes are capable of changing on a continual basis. The primary goal of such an ad-hoc network routing protocol is correct and efficient route establishment between a pair of nodes so that messages may be delivered in a timely manner. LAR is an on-demand protocol who is based on the DSR(Dynamic Source Routing). The Location Aided Routing protocol uses location information to reduce routing overhead of the ad-hoc network! Normally the LAR protocol uses the GPS(Global Positioning System) to get these location information’s. With the availability of GPS, the mobile hosts knows there physical location. Ad hoc networks are a new wireless networking paradigm for mobile hosts. Unlike traditional mobile wireless networks, ad hoc networks do not rely on any fixed infrastructure. Instead, hosts rely on each other to keep the network connected. The military tactical and other security-sensitive operations are still the main applications of ad hoc networks, although there is a trend to adopt ad hoc networks for commercial uses due to their unique properties. One main challenge in design of these networks is their vulnerability to security attacks. In this paper, we study the threats an ad hoc network faces and the security goals to be achieved. We identify the new challenges and opportunities posed by this new networking environment and explore new approaches to secure its communication. In particular, we take advantage of the inherent redundancy in ad hoc networks — multiple routes between nodes — to defend routing against denial of service attacks. We also use replication and new cryptographic schemes, such as threshold cryptography, to build a highly secure and highly available key management service, which forms the core of our security framework.

EXISTING SYSTEM

 Infra-structured Networks

The first one is to introduce a third fixed party (a base station) that will hand over the offered traffic from a station to another, as illustrated in Figure 1. The same entity will regulate the attribution of radio resources, for instance. When a node S wishes to communicate to a node D, the former notifies the base station, which eventually establishes a communication with the destination node. At this point, the communicating nodes do not need to know of a route for one to each other. All that matters is that both nodes source and destination are within the transmission range of the base station. If one of them fails to fulfill this condition, the communication will abort.

PROPOSED SYSTEM

 Infra-structure-less Networks (Ad Hoc)

            The second approach, called the Ad-Hoc, does not rely on any stationary infra structure. The concept behind these infra-structureless networks is the collaboration between its participating members, i.e, instead of making data transit through a fixed base station, nodes consequentially forward data packets from one to another until a destination node is finally reached. Typically, a packet may travel through a number of network points before arriving at its destination.

Ad-hoc networking introduces a completely new flavor of network formation. The term Ad-Hoc means, in this instance, a type instantaneous network connecting various mobile devices without the intervention of fixed infrastructure. The routers and hosts are free to move randomly and organize themselves in an arbitrary fashion, thus the network topology changes rapidly and unpredictably. Absence of a supporting structure in mobile ad-hoc networks, to a certain extent, invalidates almost all of the existing techniques developed for routine network controls in the existing wireless networks.
