A mobile various network security solution

Abstract

The On-Demand Routing Protocol is designed to work efficiently on mobile ad hoc networks. They operate in the belief that all nodes in the network are friendly, so hackers have exploited the security hole to perform some form of network attack, typically a flood attack. This type of attack is easily accomplished by flooding the route request packet into the network. Once the attack frequency is large enough, it will hinder the route discovery process of other network nodes, causing damage to network performance. This paper analyzes and evaluates the harmful effects of
flooding attack on the performance of two routing protocols AODV and AOMDV. Thereby, presenting a security solution using OTP password authentication mechanism and installing improved H(AOMDV) security protocol from AOMDV to reduce the harmful effects of flood attack. Using NS2, the paper evaluates the security effectiveness of the H(AOMDV) protocol and compares it with the H(AODV) protocol in a flooded network environment. Simulation results show that both improved protocols are very effective to reduce the harmful effects of flood attack.
