Embodiment Construction

[0064] In order to make the object, technical solution and beneficial effects of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0065] please see figure 1 , is a schematic diagram of the network of the present invention, assuming that there are 100 common nodes in the network, represented by numbered circles, a base station B is located in the center of the network, the shaded part represents the confusion ring at this time, and the arrow represents the flow direction of the data packet, all The data packet is first forwarded to the confusion ring, and the white arrow indicates that the real data packet after confusion is forwarded to the base station, and the false data packet is discarded.

[0066] please see figure 2 , the technical solution adopted in the present invention is: a method for protecting source location privacy based on a dynamic confusio...

Abstract

The invention relates to the field of privacy protection of a wireless sensor network, provides a method for protecting source position privacy in the wireless sensor network, and aims at providing and achieving a method capable of adequately protecting the source position privacy in the sensor network. The method adopts key technologies of a data packet generation method, an establishment and dynamic variation method of a confusion ring, a data packet confusion method, and the like. The method can resist attackers with global monitoring capability effectively; additional equipment is not required; the method is very low in expense and is applicable to the wireless sensor network with a limited resource; the method can balance the energy consumption of nodes in the network; a funneling effect due to the fact that the node energy close to the aggregation nodes is consumed overquickly is eliminated; the service life of the network is prolonged; and delay of an event report can be reduced effectively with the adoption of the data packet generation method based on an inhomogeneous statistical rule.

Description

technical field [0001] The invention relates to the field of wireless sensor network privacy protection, and proposes a method for source location privacy protection in the wireless sensor network. Background technique [0002] The wireless sensor network is composed of a large number of sensor nodes deployed in the monitoring area, and the sensor nodes form a multi-hop self-organizing network system through wireless communication. The nodes perceive and collect relevant information of the monitored object in real time through various integrated micro-sensors, and the information is returned to the user terminal in the form of wireless transmission through multi-hop routes. [0003] Event monitoring is a typical application scenario in wireless sensor networks. Taking event monitoring as an example, multiple nodes are deployed in the monitoring area. When a specific event occurs around a node, the node collects event information and sends the information data to the base st...
