IPv6 address configuration method of wireless sensor network based on geographical position

Abstract

The invention provides an IPv6 address configuration method of a wireless sensor network based on a geographical position. The wireless sensor network comprises full-function sensor nodes and partial-function sensor nodes; a wireless sensor network area is divided into multiple squares with identical areas, and each square is identified by coordinates; if the multiple full-function sensor nodes are contained in one square region, then only one full-function sensor node in activated state exists at the same time; in one square region, all the sensor nodes can realize one-hop communication; access nodes used for connecting the wireless sensor network and an IPv6 network are full-function sensor nodes; at most one access node is contained in one square region; and the full-function sensor nodes in the activated state adopt the stateful address distribution scheme that the partial-function sensor nodes in the square area distribute internal ID addresses in a unified way, and adopt the division method and linear detection method to produce internal ID addresses.

Description

technical field [0001] The invention relates to a method for realizing automatic address configuration in a wireless sensor network, in particular to a geographical location-based wireless sensor network IPv6 address configuration method. 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 of the technologies is the automatic configuration of IPv6 addresses in sensor networks. [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 wireless sensor network self-organization and self-configuration. . But at the same time, there are still some problems in t...

Problems solved by technology

But at the same time, there are still some problems in the implementation of the existing IPv6 address automatic configuration method in the wireless sensor network with limited resources. For example, the existing stateful address configuration scheme uses the server / client communication method to allocate IPv6 The DHCP server makes a request to apply for an address, 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 In the stateless address configuration scheme based on the Neighbor Discovery Protocol, each assigned IPv6 address needs to perform duplicate address detection in the entire wireless sensor network to ensure its uniqueness, which also leads to a large amount of control packet overhead and consumes a large amount of of web resources
