Embodiment Construction

[0060] 1. Architecture

[0061] The technical solution of the present invention is specifically composed of three parts: (1) collection of network link status by nodes; (2) calculation of optimal path; (3) safe sending and forwarding processing of data.

[0062] 2. Method flow

[0063] (1) Nodes collect network link status

[0064] The collection of link status mainly includes two functions: neighbor node information exchange and network link status broadcast. This process mainly uses two kinds of messages: "Hello" message and "Changing" message. The "Hello" message is used for information exchange between one-hop neighbor nodes. The "Changing" message is used by the node to broadcast the link changes it has mastered to other nodes in the network. The specific steps of link state collection are as follows.

[0065] ①Each node periodically sends a "Hello" message to its one-hop neighbor node, announcing the relevant information of the node, including the node ID, the netwo...

Abstract

The invention discloses a wireless broadband secure routing method for smart home control in an Internet of things environment. A proper secure transmission path is found between needs with communication requirements. The method comprises the following steps of: (1) the collection of the nodes for communication link conditions; (2) the calculation of an optimal path; and (3) the secure transmission and forwarding processing of data. The optimal path is selected by comprehensively using the information of a hop count, a node queue length, a node neighbor number and the like, so that the shortcomings of a minimum hop count routing method are overcome, and the communication quality of a wireless fidelity (WIFI) network is improved; the method can be adapted to the dynamic change of an external environment of a wireless network; in addition, the routing method is low in overhead, high in security and easy to implement; and the nodes on a forwarding path are subjected to identity authentication in the forwarding process of a data packet, and in the authentication, the security of own private data is well ensured, and the attacks of malicious nodes are effectively prevented.

Description

technical field [0001] The present invention belongs to the intersecting field of wifi (wireless fidelity, wireless broadband, hereinafter the same meaning) wireless network and information security, and particularly relates to safe routing technology in wifi wireless network. Background technique [0002] In recent years, with the rise of the Internet of Things technology, the smart home system based on wifi technology has become a research and development hotspot in the industry. Since the wifi network has a high transmission rate and the communication distance can reach 100 meters, these characteristics make it very suitable for communication in buildings. [0003] Routing technology is one of the key technologies for wifi network applications. In the smart home system, there are a lot of commands and data interactions between different home appliances and control terminals. In this process, the routing protocol will play a huge role, it can find a suitable path between...
