Problems solved by technology
However, the detection effect of this detection method depends on the set detection threshold: nodes that generate query messages at a rate higher than the set value in any period are considered malicious nodes
The problem at this time is: if the threshold is set too high, it may cause the attack nodes with low flooding frequency to slip through the net; A large number of routing query messages are generated accidentally in a short period of time and are mistaken for attack nodes

Embodiment Construction
[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0027] see Figure 1 ~ Figure 4, introduce the detection method of wireless self-organizing network route inquiry message flooding attack of the present invention, this method comprises following operation steps:
[0028] Step 1, in the wireless ad hoc network using reactive routing protocols, each node monitors and counts the routing query messages generated by its surrounding nodes (see figure 1 Shown), and listen to each route query message whether there is a route reply message: when a route query source node ( figure 1 , represented by a six-pointed star) generates a route query message and broadcasts it, and each neighbor node around it (that is, a one-hop node on the route, figure 1 Indicated by a triangle, and the communication range is i...

The invention relates to a method for detecting flooding attack by wireless self-organizing network route query, which comprises the following steps: (1) monitoring and counting route query messages produced by nodes around the node by each node and judging whether the route query messages are normal or forged by using a method for monitoring whether each route query message has a route reply message; (2) checking the counting record of the route query messages by each node per se every other set time; and if the quantity of the forged route query messages produced by a certain node around the node is found to reach or exceed a set threshold within the set time, then judging the node to be an attacking node and blacklisting the node; and (3) directly discarding and not forwarding the received route query messages sent by nodes in the blacklist any more by each node. The method only counts the forged messages of the flooding attack, separates out attacking nodes, increases correct detection rate and reduces misinformation rate to prevent the flooding attack.
Description
technical field [0001] The present invention relates to a detection method of ad hoc routing query flooding attack, to be precise, relates to a wireless self-organizing network realized by using the routing query and routing reply mechanism in the reactive routing protocol in the wireless self-organizing network The invention discloses a detection method for routing query flood attack; it belongs to the technical field of network security of data communication. Background technique [0002] The wireless ad hoc network is a new type of mobile multi-hop wireless communication network. The network does not depend on any fixed infrastructure and management center, but maintains the communication between each node in the network through mutual cooperation and self-organization among mobile nodes. Connection, while realizing data transmission. Compared with the wired network, the special feature of the wireless ad hoc network is that the network topology may change in real time, ...
