Embodiment Construction

[0043] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0044] In some application environments, such as delay-tolerant sensor networks, it is inappropriate to focus on data privacy protection, and the embodiment focuses on the location privacy protection of the sending source.

[0045] In the embodiment, each sensor node is equipped with a GPS module (Global Positioning System, GPS) and a module supporting IPV6 communication. The GPS module can perform real-time positioning of the sensor node, and each positioning obtains the current geographic location information of the sensor node.

[0046] The latitude and longitude information obtained by the GPS module, in order to protect the location information of the node, the embodiment adopts the technology of area division, which divides the coverage of the base station node into small area spaces, and all the nodes in this space use The space numb...

Abstract

The invention provides a data transmission method for an IPV6 delay-tolerant sensing network on the basis of location privacy. Different from a traditional mechanism that the privacy protection technology is focused on data transmission, information of subregions of sectors of an application space where sensing nodes are located is utilized to replace specific location information, and identities of the nodes are identified by means of IPV6 addresses. A transmission source is protected through location hiding, and delay tolerance and other network characteristics and an acquisition-comparison-transmission method are used as references. Thus, privacy information of locations of sensors is protected; a regional division method is adopted, so that geographical location information of the sensor nodes is converted into the information of the subregions, and the location information and the identify of the transmission source are hidden.

Description

technical field [0001] The invention relates to a data transmission method for an IPV6 delay-tolerant sensor network based on location privacy, and belongs to the cross field of information security, delay-tolerant network and wireless sensor network technology. Background technique [0002] With the rapid development and maturity of communication technology, embedded computing technology and sensor technology, micro-sensors with sensing, computing and communication capabilities have begun to appear around the world. Network, WSN) is a new research field in computer science technology. Wireless sensor nodes maximize the ubiquity of communication networks and can be widely used in various special environments such as space, land, underground, and underwater, providing a series of information such as unattended information perception, collection, monitoring and processing. Serve. [0003] Under certain circumstances, some wireless sensor networks for non-real-time applicatio...
