A Routing Method Based on Node Reputation Evaluation in Wireless Sensor Networks

Abstract

The present invention proposes a routing selection method based on wireless sensor network node reputation evaluation. Through research on wireless sensor networks, on the basis of AOMDV multi-path routing protocol, combined with Bayes algorithm, respectively establishes routing vector model, energy evaluation model and communication trust Model, through the above model to analyze the influence of routing vector factors, communication factors and energy factors in wireless sensor nodes on their own reputation, objectively select safe and efficient wireless sensor routing nodes; enable wireless sensor networks to more effectively identify multiple factors Internal attack nodes in the network, prevent malicious node attacks, improve the success rate of data transmission, solve internal attack security problems that cannot be solved by traditional password security authentication security mechanisms, and make internal attack security of wireless sensor networks in an open environment to a higher level .

Description

Technical field[0001]The invention belongs to the technical field of wireless sensor networks, and particularly relates to a routing 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 human life style in the future and is regarded as one of the most important technologies in the 21st century. Wireless sensor networks appeared at the end of the 20th century. In 1998, the “smart dust” concept proposed by the US Department of Defense began, which opened the prelude to the research of wireless sensor networks; in 2001, the US Army put forward the “smart sensor network communication” plan, which set off WSN Applied research in the military. Information industry giants such as the US Department of Defense, various military departments, Intel Cor...

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.
