Embodiment Construction

[0052] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0053] A node privacy protection method based on directed random routing in a wireless sensor network, the steps of which include:

[0054] Step 1: If figure 1 As shown, the establishment of the grid. After the nodes in the network are randomly deployed, the entire network is divided into edge lengths The grid, r is the communication radius of the node, and each grid determines the coordinate value (x, y) with the network center as the origin according to the coordinate system;

[0055] Step 2: If figure 2 As shown, the establishment of the ring. Set up a square ring with the center of the network as the center of the ring, and the ring interval is l. According to the distance from the network center, the ID numbers of each ring are 1, 2, 3...;

[0056] The establishment of the grid and square ring in step 1 and step 2 is a virtual exis...

Abstract

The invention relates to a node privacy protection method based on directional random routing in a wireless sensor network. The steps include: establishment of a grid, establishment of a ring, determination of the grid to which a node in the network belongs, determination of the ring to which a node in the network belongs, and real data packet Routing, routing of obfuscated packets in six steps. By introducing obfuscated data packets in all directions in the network to avoid the attacker's directional attack, balance the traffic in the network, and perform a loop at the beginning of the data packet to prolong the security period of the network. Through the time domain obfuscation mechanism, the attacker cannot continue to trace back to the previous hop node. The directional routing strategy of real data packets increases the diversity of routing and increases the attack difficulty of attackers. A node privacy protection method based on directional random routing in the wireless sensor network described in the present invention can simultaneously protect the source node and the base station node through the design of the grid and the ring route, and is applicable to the situation of mobile source nodes and multi-source nodes, It has good scalability.

Description

technical field [0001] The invention relates to a node privacy protection method based on directional random routing in a wireless sensor network, and belongs to the technical field of wireless sensor network privacy protection. Background technique [0002] A wireless sensor network is a wireless network that serves different applications and is composed of many sensor nodes capable of sensing, collecting and sending data. A common application is the detection and tracking of objects, which are often objects that require privacy protection. For example, the most typical "panda hunter" model needs to protect pandas from being discovered by hunters. This is the problem of location privacy protection. Location privacy protection is further divided into source node location privacy protection and base station location privacy protection. For the privacy protection of the source node, the method of adding a fake source node to the network to confuse the attacker is usually use...
