Security routing method for internet of things based on topological quick check

Abstract

The invention discloses a security routing method for internet of things based on topological quick check. The method comprises the following steps: initializing node routing strategies; defining the routing strategies by sensing nodes; and building cluster structure topology, inter-cluster interconnection and target nodes, wherein the strategies comprise a source strategy and a forwarding strategy; preferentially selecting a node with a slack forwarding strategy as a cluster center node; sharing each state through a proactive method, and achieving the inter-cluster interconnection; and transmitting a data packet to a target node by virtue of an AODV protocol with a tag. The data packet is relayed by virtue of the center node, so that relatively high routing success rate can be maintained; and meanwhile, routing overhead between highly connected nodes is much smaller than reactive routing overhead on the overall path, so that the routing discover overhead is reduced; the routing efficiency is improved; and the security routing method is suitable for a network environment which is relatively large in scale and relatively stable.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and in particular relates to a secure routing method for the Internet of Things based on fast topology verification. Background technique [0002] The Internet of Things is an information carrier based on the Internet, traditional telecommunication networks, etc., which enables all ordinary physical objects that can be independently addressed to realize interconnection and intercommunication. Most of its interconnection core technologies are based on standards, interoperable and self-configurable. communication protocol. At present, for security reasons, environments such as homes, offices, and factories mostly use autonomous sensing subnets. [0003] With the widespread application of sensing nodes such as smart terminals and mobile devices in the Internet of Things, in order to reduce costs and increase access area between sensing subnets, sensing nodes deployed by different ser...

Problems solved by technology

The sensing layer of the Internet of Things integrates various types of networks, and communication devices are often deployed in advance without special monitoring. Therefore, in the face of the highly open and heterogeneous sensing environment of the Internet of Things, only using privacy protection at the terminal level cannot Completely guarantee the privacy and security of terminal data, sensitive data is very likely to be obtained by malicious organizations during transmission
