Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0020] A traceability and tracking method based on fair probability marking in a wireless sensor network. In the traceability and tracking process of a planar wireless sensor network, different node marking probabilities are used to mark nodes at different distances from a base station for data packets passing through the node. , so that each node contained in all packets arriving at the base station is marked the same number of times:
[0021] Nodes near the base station use a lower node labeling probability, and nodes far from the base station use a higher node labeling probability;
[0022] The node marking probability refers to the probability that the node identification number information is added to the data packet when the data packet passes through the node;
[0023] The node being marked means that when a data packet arriving at the base stat...

The invention discloses a traceability method based on fair probability marking in a wireless sensor network. The method is proposed for the most widely used 2-dimensional planar wireless sensor network fair marking method in the prior art. Nodes mark data packets with unequal probabilities. Nodes close to the base station have a small probability of marking passing data packets, and nodes far from the base station have high probability of marking passing data packets, so that among all data packets received by the base station, every The marked times of each node are equal, that is, each node is marked fairly; the method of the present invention provides an accurate calculation formula of the marking probability at any distance from the base station, and can quickly determine the passing data of each node pair The probability of packet marking, strong adaptability, reduces the convergence time of network source tracing, and has a significant effect on prolonging the life of the network.
Description
technical field [0001] The invention belongs to the field of wireless sensor network security, and particularly relates to a source tracing method based on a fair probability mark in a wireless sensor network. Background technique [0002] A wireless sensor network is a wireless network composed of a large number of sensor nodes that communicate with each other through multi-hop wireless links and in a self-organizing and multi-hop manner. It can be widely used in industrial monitoring, agriculture, civil, environmental monitoring, battlefield , ocean, fire and other special environments and applications, it is considered to be one of the key basic technologies of the future important IoT network. The security of wireless sensor networks is an important research topic. Among them, traceability is an important mechanism to ensure security in wireless sensor networks, and its research is of great significance. [0003] Traceability is an important mechanism to ensure the sec...
