Active protection system for wireless self-organizing network

Abstract

The invention provides an active protection system for a wireless self-organized network in the technical field of network security, comprising a monitoring agent, a decision-making agent and a blocking agent, wherein the monitoring agent is in charge of acquiring action information of each neighborhood node around the monitoring agent; the decision-making agent is in charge of monitoring a region in the network, gathering information of the monitoring agent in the region, and making the gathered information formed into an action sequence of a certain node in a period, and compares the action sequence with a routing protocol, if the action does not accord with the routing protocol, the action is determined to be an intruder, after the intruder is found, the decision-making agent transmits a protection command to the blocking agent; the blocking agent forms a moving firewall to encircle and separate the intruder, after the blocking agent receives the protection command transmitted by the decision-making agent, simultaneously, a communication link of the network is disconnected to prevent the intruder from sending and receiving any messages. The active protection system greatly reduces the network resource consumed by active protection.

Description

technical field [0001] The invention relates to an intrusion response system in the technical field of network security, in particular to a wireless ad hoc network active protection system. Background technique [0002] As a new type of mobile multi-hop wireless network, wireless ad hoc network has many different characteristics from traditional wireless networks. It does not depend on any fixed infrastructure and management center, but maintains the connection of the network and realizes the transmission of data through mutual cooperation and self-organization among mobile nodes. The wireless ad hoc network does not need to set up any fixed facilities in advance, such as base stations, so it can be quickly deployed and applied in various environments, such as military affairs, disaster relief, temporary meetings, etc. [0003] With the wide application of wireless ad hoc networks, the security of wireless ad hoc networks becomes increasingly important. Existing methods to...
