Thing Internet gateway of heterogeneous wireless network and control method thereof

Abstract

The invention discloses a thing Internet gateway of a heterogeneous wireless network and a control method thereof. Function, such as protocol conversion, route selection, data exchange and the like, is provided in the network interworking process of different structures or protocols of the thing Internet. The gateway is a multi-layer cascading gateway and comprises a main gateway used for communication, sensor network management and topology management, and sub-gateways responsible for converting and penetrating a short-range wireless protocol and receiving front-end sensing network data, wherein each of the sub-gateways is connected with the main gateway. The limitation to the access ability of a sensor network is overcome, so that various front-end sensing nodes access a thing Internet platform without barriers; free networking of the sensor network front end is realized by taking full advantage of the conventional communication capacity and cascading gateway technology at the same time; the problems of the failure management and performance management of the sensor network front end are effectively solved; and the safety, the reliability and the stability of the sensor network and neurones are enhanced.

Description

Technical field The present invention relates to the technical field of data communication, in particular to an IoT gateway of a heterogeneous wireless network that is composed of multi-layer gateways with a cascading structure under a heterogeneous wireless network environment to realize effective interconnection between things And control methods. Background technique The IoT gateway is an important part of the IoT system platform, and it is also a core component that realizes data transparent transmission, solves multiple heterogeneous technologies, and controls the networking of the front-end perception network. The Internet of Things refers to a huge network formed by combining various sensing devices with the Internet, which can connect all products to the network, and ultimately realize the transfer of information between people and things, and things and things. The essence of the Internet of Things is based on the perception of infinite sensor network technology and R...

AI Technical Summary

Problems solved by technology

There are many types of on-site networks and different standards. All kinds of on-site networks are different. There is no unified standard for the hardware capabilities and software APIs of the gateway, which causes the complexity of the underlying network and makes the development and use of the Internet of Things more difficult. and require more cost

Due to the strict limitations of the transmission mode and protocol of the front-end sensing equipment, the existing Internet of Things cannot realize the effective interconnection between things.

Due to the limitation of the access capability of the sensing network, the self-organizing network of the sensing network cannot be realized within the area, so the front-end sensing nodes that do not have communication protocol capabilities such as SMS, USSD, TCP, and UDP cannot access the IoT platform
