But at the same time, there are still some problems in the implementation of the existing IPv6 address automatic configuration method in WSN with limited resources. For example, the existing stateful address configuration scheme uses the server / client communication method to allocate IPv6 addresses, that is, the node sends the DHCP server A request to apply for an address is made, and then the DHCP server uniformly assigns IPv6 addresses to the nodes in the network. Obviously, this address configuration scheme brings a lot of control packet overhead and consumes a lot of storage resources; in the existing neighbor-based In the stateless address configuration scheme of the discovery protocol, each allocated IPv6 address needs to perform duplicate address detection in the entire WSN to ensure its uniqueness, which also leads to a large amount of control packet overhead and consumes a large amount of network resources

Embodiment Construction
[0048] The present invention provides a distributed wireless sensor network IPv6 address configuration implementation method, in the method, each sensor node in the wireless sensor network can obtain a globally unique IPv6 address, and the IPv6 network node uses the wireless sensor node's The IPv6 address realizes the communication with each other and obtains the data information collected by the sensor nodes.
[0049] figure 1 Shown is a schematic diagram of the wireless sensor network tree topology structure described in the present invention, the wireless sensor network includes four types of nodes: new nodes, access nodes, distribution nodes and ordinary nodes; wherein, the new nodes are newly added wireless sensors A mobile sensor node that does not have an IPv6 address on the network and does not assign an IPv6 address to other nodes; an access node is a sensor node that connects the wireless sensor network to the IPv6 Internet, and is connected to the access router of t...

The invention provides a distributed wireless sensor network-based IPv6 address configuration implementing method. A wireless sensor network comprises four classes of nodes, namely new nodes, access nodes, distribution nodes and common nodes, wherein the new nodes are mobile sensor nodes which do not acquire an IPv6 address; the access nodes and the distribution nodes are nodes which have acquired the IPv6 address and can allocate the IPv6 address for other nodes; and the common nodes are nodes which have acquired the IPv6 address but cannot allocate the IPv6 address for the new nodes. An access router, the access nodes, the distribution nodes and the common nodes form a tree structure, the root node of the tree structure is the access router; the nodes in the tree structure comprise k child nodes at most, wherein k is a positive integer; and the new nodes acquire the IPv6 address from the distribution nodes or the access nodes, complete node conversion, and simultaneously form a parent child relation with the distribution nodes or the access nodes.
Description
technical field [0001] The invention relates to a method for realizing automatic address configuration, in particular to a method for realizing IPv6 address configuration based on a distributed wireless sensor network. Background technique [0002] With the continuous maturity and development of the next-generation network (IPv6 network), the realization of all-IP communication interconnection between the wireless sensor network and the next-generation network has become an inevitable trend in future development. One is the automatic configuration of the IPv6 address of the sensor network. [0003] IPv6 address automatic configuration is an important technical feature of IPv6. It can configure a unique IPv6 address for each interface without human intervention. This feature is very consistent with the design goal of WSN self-organization and self-configuration. But at the same time, there are still some problems in the implementation of the existing IPv6 address automatic c...
