Embodiment Construction

[0025] 1. A method for realizing 6LoWPAN and IPv4 network interconnection according to the present invention, comprising:

[0026] 11) The 6LoWPAN network DNS collects node device information, and the IPv4 host queries the IPv4 conversion address of the 6LoWPAN node through DNS, and initiates access to the node, mainly including the following steps:

[0027] (1) The 6LoWPAN network DNS collects the device information of all 6LoWPAN nodes and stores it in the database for query by the DNS46 module;

[0028] (2) The IPv4 host initiates an A record query request for a 6LoWPAN node, and the DNS46 module acts as a proxy server to convert the received A record query message into an AAAA record query message and send it to its configured DNS server (here refers to 6LoWPAN network's DNS server);

[0029] (3) The DNS server returns an authoritative DNS query response message with an AAAA record to the DNS46 module;

[0030] (4) DNS46 module parses this response message, extracts the ...

Abstract

The invention relates to a method and device for achieving 6LoWPAN and IPv4 network interconnection, and belongs to the fields of IPv6 transition techniques and wireless sensor network techniques.The device comprises a DNS proxy server unit, a 6LoWPAN network DNS server, a conversion address managing unit, a protocol conversion unit, a 6LoWPAN accessing unit and an IPv4 network accessing unit.The method comprises the steps that an IPv4 host acquires an IPv4 conversion address of a network node through the proxy server unit and actively accesses the 6LoWPAN network node through the protocol conversion unit, and the 6LoWPAN network node uploads sensing information data to the IPv4 host through the protocol conversion unit.According to the method and device, the problems that in the prior art, the IPv4 host cannot actively access an IPv6 node through a stateful protocol conversion technique, and a state-free protocol conversion technique consumes a large amount of IPv4 address space can be solved.

Description

technical field [0001] The invention belongs to the field of IPv6 transition technology and wireless sensor network technology, and relates to a method and device for realizing interconnection between 6LoWPAN and IPv4 network. Background technique [0002] WSN (WirelessSensorNetwork) has become one of the international hotspot research areas that have attracted much attention and highly integrated knowledge in the world. Its purpose is to collaboratively perceive, collect and process the information of sensing objects in the network coverage area, and send it to the observer. As far as its purpose is concerned, WSN must be connected to the external network, so that the observer can remotely monitor the perceived object through the external network, which is more realistic. As the network with the widest coverage and the highest popularity in the world, the Internet will undoubtedly become the best access object for WSN. However, WSN nodes are limited by their own hardware p...
