Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] An unequal probability marking method based on logs and migration traceability in wireless sensor networks. In a wireless sensor network using log and migration traceability strategies, nodes at different distances from the base station adopt unequal marking probabilities: near base station The nodes in the area adopt a lower marking probability, and the nodes in the far base station area adopt a higher marking probability; and the wireless sensor network is divided into three areas, namely the hot area, the buffer area and the rich area;

[0035] The hot zone refers to the area where the nodes that are 1 hop away from the base station are located, the buffer zone is the area where the nodes that are 2-4 hops away from the base station are located, and the rich area refers to that the nodes in the wireless network sensor are not in the hot zone T...

Abstract

The invention discloses a marking method based on the unequal probabilities during log and migration trace source tracking in a wireless sensor network. According to the method, the unequal marking probabilities are adopted for nodes different distances away from base stations in the wireless sensor network adopting a log and migration trace source tracking strategy; lower marking probabilities are adopted for the nodes of near base station regions, and higher marking probabilities are adopted for the nodes of far base station regions. The marking probabilities of the nodes of the far base station regions are further improved based on existing strategies, the probability that the nodes are marked and the total marking amount of a system can be increased, and accordingly the safety performance of trace source tracking can be improved. The storage capacity of the nodes is not needed to be increased based on increase of the marking probabilities, and the service life of the network is not influenced.

Description

technical field [0001] The invention belongs to the field of wireless network security, and in particular relates to a method for marking unequal probabilities in wireless sensor networks based on log and migration traceability. 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 mechanis...
