A routing method based on reputation evaluation of a wireless sensor network node

Abstract

The invention provides a routing method based on reputation evaluation of a wireless sensor network node. By studying a wireless sensor network, and based on an AOMDV multipath routing protocol, The method comprises the steps of establishing a routing vector model, an energy assessment model and a communication trust model respectively by combining a bayes algorithm, analyzing the influence of routing vector factors, communication factors and energy factors in the wireless sensor nodes on the reputation of the wireless sensor nodes through the models, and objectively selecting safe and efficient wireless sensor routing nodes, so that the wireless sensor network can identify attack nodes in the multi-factor network more effectively; the malicious node attacks are prevented, the success rateof data transmission is improved, the internal attack security problem which cannot be solved by a traditional password security authentication security mechanism is solved, and the internal attack security of the wireless sensor network in an open environment is more hierarchical.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor networks, in particular to a routing selection method based on reputation evaluation of wireless sensor network nodes. Background technique [0002] The sensor network combines sensor technology, communication technology and computer technology to realize the collection, transmission and processing of information. It will have a profound impact on the future human life style and is considered to be one of the most important technologies in the 21st century. Wireless sensor networks appeared at the end of the 20th century. In 1998, the concept of "smart dust" proposed by the US Department of Defense began, which opened the prelude to the research of wireless sensor networks; Applied research in the military. The U.S. Department of Defense, various military departments, the U.S. Intel Corporation, the U.S. Microsoft Corporation and other giants in the information industry have also started ...

AI Technical Summary

Problems solved by technology

The damage caused by the use of captured nodes to participate in normal communication will eventually lead to node energy exhaustion and routing black holes caused by node black hole attacks, false routing information attacks, selective forwarding attacks, Sybil attacks, hello flood attacks, fake response attacks and Key point attacks and other new types of attacks

[0006] To sum up, the security mechanism of traditional password security authentication alone cannot solve the internal attack security problem of wireless sensor network in the current open environment.
