Embodiment Construction

[0016] like figure 1 As shown, nodes 1 to 8 are neighbor nodes of the central node, and the distance between them is only one hop. The neighbor nodes are only located in the south, southeast, east, northeast, north, northwest, and These eight locations are west and southwest. Nodes 1 to 4 are nodes in the east direction, and nodes 5 to 8 are nodes in the west direction. During directional routing, if the directional routing direction is east, the central node can only forward data to one of the neighbor nodes 1 to 4, and if the directional routing direction is west, the central node can only forward data to neighboring nodes 5 to 4. One of Node 8.

[0017] figure 2 It shows the location privacy protection process diagram in the present invention:

[0018] (1): The neighbor nodes of each node are divided into two categories according to the east-west direction, one is the east direction node, and the other is the west direction node;

[0019] (2): The source node sending ...

Abstract

The invention discloses a network position privacy protection method of a wireless sensor. The method comprises the following steps: dividing the data to be sent into m fragment data by a source node; routing the m fragment data to n different pseudo phantom nodes which are selected at random though a directional routing method; routing the received fragment data to a target node through the n pseudo phantom nodes; reconstituting the fragment data through the target node after receiving all fragment data. Compared with the prior art, the method of multi-phantom pseudo source node is adopted, then the difficulty of an attacker to track a real source node can be increased, so that the privacy of the position of the source node can be effectively protected; and moreover, the method is suitable for middle and large scaled sensor networks.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a location privacy protection method for a wireless sensor network. Background technique [0002] In recent years, the application of Wireless Sensor Networks (WSN) has become more and more widespread, and its security issues have attracted more and more attention from researchers at home and abroad. The privacy protection technology of wireless sensor network is an important research direction of wireless sensor security technology, and it is a major challenge for wireless sensor network. From the subject of the research content, the privacy issues in wireless sensor networks can be divided into data-oriented privacy security and location-oriented privacy security. Location privacy is an important part of wireless sensor network privacy. [0003] After searching the existing technology, it is found that for the location privacy protection of wireless sensor networks, the re...
