Problems solved by technology

[0003] The location privacy of source nodes seriously restricts the further application development of WSNs. Researchers have successively proposed random routing methods based on random walk mechanism, phantom routing based on intermediate phantom nodes, and false sources based on false data sources to hide real source nodes. methods and multipath routing methods, etc.

Embodiment Construction

[0037] The content of the present invention will be further elaborated below in conjunction with the accompanying drawings and embodiments, but it is not intended to limit the present invention. Example:

[0038] refer to figure 1 , a dynamic token-based multi-path source node location privacy protection routing method, comprising the following steps:

[0039] 1) Define the network structure: the wireless sensor network consists of a large number of sensor nodes and a gateway sink node, which are evenly distributed in the monitoring area. The sensor nodes are responsible for monitoring the target. After the sensor node monitors the target, it initiates information transmission. node, the source node will collect the target information in time t s In order to periodically send data packets, they are transmitted to the gateway sink node in a hop-by-hop manner. The network structure of this example is set as follows:

[0040] The network is initialized as a 1000m×1000m network...

Abstract

The invention discloses a dynamic token-based multi-path source node location privacy protection routing method, which is characterized by comprising the following steps: 1) defining a network structure; 2) defining an attacker model; 3) token link transmission; 4) Event loop and interference loop transmission path; 5) Multi-path transmission. This method makes it difficult for attackers to backtrack to the source node, can prolong and resist backtracking attacks, increase the security time of the network, and realize the privacy protection of the source node location. In the loop transmission stage, the participation of some nodes can save network energy. power consumption and improve network life.

Description

technical field [0001] The invention relates to a wireless sensor network security communication technology, in particular to a dynamic token-based multi-path source node location privacy protection routing method (Dynamic Token and Multi-Path, DTMP for short). Background technique [0002] Wireless Sensor Networks (WSNs) is the foundation of the Internet of Things (Internet of Things, referred to as IoT). With the development of IoT technology, WSNs are more and more widely used. WSNs are wireless networks formed by a large number of sensor nodes in a self-organizing manner, which are used to perceive, monitor and describe the physical world. The field has received extensive attention. WSNs are often deployed in harsh environments and unguarded natural scenes. Internal resources, especially node power, are difficult to replenish. Random node distribution positions increase the complexity of network topology. Hardware tailoring for energy and volume makes the calculation an...
