Embodiment Construction

[0030] A non-limiting embodiment is given below in conjunction with the accompanying drawings to further illustrate the present invention. It should be understood, however, that these descriptions are exemplary only, and are not intended to limit the scope of the invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0031] Such as figure 1 For such figure 1 As shown, the access device needs to complete the interconnection and intercommunication requirements between the sensor network and the Internet, and the wireless sensor network end is the introduction of the IPv6 protocol, and the Internet end is based on the IPv4 protocol, and the access device needs to complete the two-layer and three-layer protocol. conversion. (The following paragraphs are for Figure 1The overall description of the processing process of the content of the invention is...

Abstract

The invention relates to a method for supporting parallel access of multiband 6LoWSNs (IPv6 over low power wireless sensor networks) to the internet. Five wireless sensor network access channels are designed according to the bands and types of the wireless sensor networks and are named as channels F1 to F5; the status of each access channel is judged by means of port polling; 433MHz, 470MHz, 780MHz, 2.4GHz and WiFi5 sensor networks are used as sub-network access terminals; a network layer of each sensor network is based on the IPv6 protocol. Boundary nodes of the sensor networks are used for managing and acquiring data information network nodes which the boundary nodes belong to and uploading the acquired data to access equipment; after the access equipment finishes identification of the data channels and adapting of network layer protocols (IPv6 and IPv4), and the data is finally transmitted to the IPv4 based internet. The access equipment designed can be well applied to sensor network expansion and extension scenes, allowing an external network to acquire and share internal resources of the sensor networks; the method of access to multiple channels is good in extensibility.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a sensor network access method, a protocol adaptation method, a data packet transmission method, a system and a communication device, in particular to a method for supporting multi-band 6LoWSN parallel access to the Internet. Background technique [0002] As the perception network of the physical world, the wireless sensor network realizes the information collection of the attributes of things and provides the quantified value of the attributes of the physical world. However, the locality of wireless sensor networks limits the service scope of these quantitative values. Therefore, enabling the internal information resources of wireless sensor networks to be remotely monitored and applied by observers is a key technology in current research on wireless sensor networks. Expansion of sensor network resources and network extension are the main purposes of the study. The intercon...
