Active protection method of wireless MESH network intrusion based on signal detection

Abstract

The invention relates to an active protection method of wireless MESH network intrusion based on signal detection, which is as follows: after an accessed mesh router (MR) founds the attack of an invasion microcomputer (MC) by using an invasion detection technology, the MR enters a corresponding detection response state, namely the MR records the invasion MC into the blacklist of the MR and then spreads out the information of the invasion MC; and surrounding MRs enter a continuous monitoring state and take corresponding measures after receiving the broadcast of the blacklist. When the invasionMC escapes, part of the MR in the continuous monitoring state continues to broadcast the information of the invasion MC, so that no matter how the intrusion MC escapes, the MC can always be surrounded by a mobile firewall once the attack behavior of the invasion MC is found, thus maximally eliminating the adverse influence of the invasion MC on network to ensure normal operation of the network, and simultaneously greatly reducing the network source consumed by active prevention. The method of the invention is carried out automatically during the whole process without manual intervention, thusrealizing real-time active invasion prevention.

Description

technical field [0001] The invention relates to an active protection method for wireless MESH network intrusion based on signal detection, and belongs to the technical field of network communication security. Background technique [0002] Wireless Mesh Network WMN (Wireless Mesh Network) is a multi-hop, self-organizing and self-healing broadband wireless network. Each node in the wireless MESH network is connected to each other in a wireless multi-hop manner through other adjacent network nodes. The nodes in the network are divided into two categories: one is the terminal node MC (Mesh Client), and the other is the mesh router MR (Mesh Router). MC can be notebook computer, PDA, Wi-Fi mobile phone, RFID reader and wireless sensor or controller etc., MC can have high mobility like the node in Ad hoc. The position of MR is relatively fixed, and it is responsible for connecting terminal node MC to realize the network access of MC; at the same time, some MRs also have a gateway...

AI Technical Summary

Problems solved by technology

However, for a large-scale wireless MESH network, the realization of this technical measure will not only bring huge unnecessary packets and their transmission overhead, but also, in the case of multiple intruders, will Adverse impact on normal network traffic

Therefore, it is not ideal in practical applications in wireless MESH networks
