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 (Location Aided Routing) is an on-demand protocol which 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 know their 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.
