Cluster-based 6lowpan wireless sensor network address configuration method

Abstract

The invention provides a 6LoWPAN wireless sensor network address configuration method based on a cluster. The 6LoWPAN wireless sensor network is connected with an IPv6 internet through an externally connected route; the 6LoWPAN wireless sensor network comprises cluster head nodes, in-cluster nodes and new nodes; the cluster head nodes are fully functional nodes with IPv6 addresses, the in-cluster nodes are partially functional nodes with IPv6 addresses, and globally unique IPv6 addresses can be obtained by the cluster head nodes or the in-cluster nodes from neighbor nodes without repeated address detection. The address configuration process is achieved through beacon frames without extra cost, so that address configuration cost and delay are reduced to a large extent, and the address configuration efficiency is improved. The 6LoWPAN wireless sensor network address configuration method based on the cluster can be used in multiple fields of traffic road condition detection and control, agriculture engineering and the like and is wide in application prospect.

Description

technical field [0001] The invention relates to a method for realizing wireless sensor network address configuration, in particular to a cluster-based 6LoWPAN wireless sensor network address configuration method. Background technique [0002] The communication between nodes in the wireless sensor network is realized through the forwarding and routing of intermediate nodes, therefore, each node must be equipped with a unique address to achieve communication, therefore, one of the key technologies that need to be solved to realize the wireless sensor network is Address autoconfiguration problem. [0003] The current address configuration is divided into two forms: stateful address configuration and stateless address configuration. The stateful address configuration scheme uses the server / client communication method to assign addresses, that is, the node requests the server to apply for an address, and then the server unifies the network The nodes within are assigned addresses...

AI Technical Summary

Problems solved by technology

Due to the limited resources of the wireless sensor network, it is difficult to play the role of the server, so the stateful address configuration scheme cannot be applied to the wireless sensor network

In the stateless address configuration scheme, each assigned address needs to perform duplicate address detection in the entire network to ensure its uniqueness, resulting in a large amount of control packet overhead and consuming a large amount of network resources, so it is not applicable Used in wireless sensor networks
