Wireless heterogeneous network and communication method for same

Abstract

The invention relates to a wireless heterogeneous network and a communication method for the same. A header conversion module is arranged in a coordinator of a Zigbee network, and is used for converting a header of a data packet for communication between different networks into a corresponding format; a 16-bit short address and extended unique identifier (EUI)-64 address mapping table is arranged in each of the coordinator of the Zigbee module and a border router of an Internet protocol version 6 over low-power and lossy network (6LoWPAN), and comprises a mapping relationship between 16-bit short addresses and EUI-64 addresses of intra-domain nodes and an address mapping relationship of extra-domain nodes. Each 6LoWPAN domain or Zigbee domain is set into an IPv6 multicast group to further prevent a broadcast storm. When a 6LoWPAN domain communicates with a Zigbee domain, the 6LoWPAN domain and the Zigbee domain share a group ID, and when the 6LoWPAN domain stops communicating with the Zigbee domain, sharing is canceled. A 6LoWPAN node and a Zigbee node can effectively communicate with each other under the condition of keeping the conventional protocols of the 6LoWPAN network and the Zigbee network unchanged, and the broadcast storm can be prevented.

Description

technical field [0001] The present invention relates to a wireless heterogeneous network and a communication method thereof, in particular to a Zigbee-Ipv6-6LoWPAN wireless heterogeneous network and a communication method thereof. Background technique [0002] IEEE802.15.4 is a set of low-power and low-speed short-distance wireless transmission protocols. As the basis of 6LoWPAN and Zigbee protocols, it describes the physical layer and media access control protocol of low-speed wireless personal area networks. [0003] Zigbee formulates the network layer and application layer of the short-distance wireless communication standard, defines the data interface and management interface between each layer, provides a rich application layer framework and security management system, and formulates corresponding application specifications for different applications . Compared with common wireless communication standards, the Zigbee protocol stack is compact and simple, and the speci...

AI Technical Summary

Problems solved by technology

The dual-stack gateway can only realize the intercommunication between the Zigbee and 6LoWPAN nodes without going through the IP network, and cannot realize the far-distance nodes, that is, the interaction between the Zigbee domain and the 6LoWPAN domain far away

Dual-stack nodes are not suitable for nodes with power consumption and resource constraints

Therefore, these two solutions cannot truly realize the integration between heterogeneous sensor networks of the Internet of Things and the ubiquitous mode of ubiquitous resources and ubiquitous networks.
