Abstract


Mobile Ad Hoc Networks, with the rapid development of wireless communication technology and the emergence of a new network. It is an autonomous wireless multi-hop network, there is no fixed infrastructure, all nodes can move in any way and can be dynamically maintained contact with other nodes. In recent years, mobile Ad Hoc network flexibility and practicality, making it in many fields have been widely used. However, due to the non-mobile Ad hoc network centrality and media openness, making it vulnerable to various attacks, intrusion response is routed across the network security plays an important role. This paper introduces the mobile Ad Hoc network basics, such as network architecture, security problems, etc., and then introduced the intrusion response technology research status quo. Due to the current mobile Ad Hoc network routing protocol for many attacks, the paper then analyzes the AODV routing protocol and typical attacks against AODV and discussed the intrusion response technology in mobile Ad Hoc network applications, indicating that you can take advantage of the mobile Agent and Mobile Ad Hoc Networks have in common to design intrusion response system. Then, we propose a Mobile Agent-based technology for mobile Ad Hoc network intrusion detection and response model. In the model, this paper monitoring Agent, decision-making Agent, Agent blocking three different functions of Mobile Agent mutual cooperation to complete response tasks. Article on the function of each module in the system are carried out a detailed analysis of the response mechanism in the active part, this paper analyzes how to make decisions and respond in response to execution module presents a mobile firewall mechanism intruders active response. Mobile Firewall combines features of Mobile Agent through a layer formed around the intruder moves to cut off the intruder firewall other nodes in the network communication, so that the intruder isolated on a network, to isolate and destroy invaders purpose . In order to more clearly illustrate the working process of intrusion response systems, this section Finally, an application example of the effectiveness of the system. Finally, the use of NS-2 platform for system simulation. Simulate three different modes did not join the invasion response mechanism and response mechanism to join a network, packet transmission rate from the perspective of this paper verified the effectiveness of intrusion response systems.
