Multi-path safety topology control method with intrusion tolerance capacity

Abstract

The invention relates to a multi-path safety topology control method with intrusion tolerance capacity, which comprises the steps of: cluster head selection, i.e., determining an optimal cluster number according to an initialization parameter, calculating cluster head election probabilities and cluster head competition radii, and determining cluster head nodes; clustering, i.e., selecting to add non-cluster-head nodes into an optimal cluster according to residual energy and node distance information of a cluster head which sends out an invitation; routing establishment, i.e., enabling a sourcenode to establish a single hop of single path by adopting direct communication or establish multiple hops of paths by adopting an indirect communication mode according to different transmission distances with target nodes, and storing routing information; and data transmission, i.e., enabling the source node to carry out patch transmission on data to the target nodes according to the establishedpath by combining (k, n) threshold secret sharing scheme. According to the invention, in a case that a malicious node exists in a network and a data transmission path is damaged, normal transmission of the data can be ensured so as to achieve effects of balancing energy consumption and prolonging the life cycle of the network.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a multi-path security topology control method with intrusion tolerance capability. Background technique [0002] With the development of network informatization, people have a higher pursuit of the popularization and facilitation of communication, and the development and expansion of the Internet of Things has become an inevitable trend of the times. The application of Heterogeneous Wireless Sensor Networks (HWSNs) plays a crucial role in the development of the Internet of Things. As a wireless self-organizing communication network composed of different types of sensor nodes, HWSNs can better reflect the heterogeneity and polymorphism of the physical world, but most of the heterogeneous nodes still have limited resources in terms of computing power, memory, and energy. It is often placed in an open environment, causing wireless communication to be easily interfe...

As a wireless self-organizing communication network composed of different types of sensor nodes, HWSNs can better reflect the heterogeneity and polymorphism of the physical world, but most heterogeneous nodes still have limited computing power, memory, energy and other resources. And it is often placed in an open environment, causing wireless communication to be easily interfered, making the network extremely vulnerable to malicious attacks, and posing a serious threat to network security
