Realization method of 6LoWPAN (IPv6 over Low power Wireless Personal Area Network) wireless sensor network system

Abstract

The invention provides a realization method of a 6LoWPAN (IPv6 over Low power Wireless Personal Area Network) wireless sensor network system. The system comprises four sensor nodes: a new node, access nodes, cluster head nodes and cluster nodes, wherein the cluster head nodes comprise fixed cluster head nodes and a mobile cluster head node; the access nodes and the fixed cluster head nodes have routing and forwarding functions; and one access node and more than one fixed cluster head nodes form a tree structure to form a routing backbone network of a 6LoWPAN wireless sensor network. The cluster nodes are used for collecting data, and the data is routed through the tree structures formed by the access nodes and the fixed cluster head nodes. A cluster comprises one cluster head node and a plurality of cluster nodes, and the cluster nodes are in the jump range of the cluster head node. A topological structure takes the shape of a star. The fixed cluster head nodes or the access nodes are used for distributing IPv6 addresses for other cluster head nodes, and the cluster nodes obtain the IPv6 addresses from the cluster head nodes.

Problems solved by technology

However, there are still some problems in the existing IPv6 address automatic configuration methods in wireless sensor networks, for example, stateful address configuration will bring a large amount of control message overhead, and stateless address configuration that generates IPv6 addresses based on MAC addresses has a negative effect on the communication between sensor nodes. Routing addressing does not bring any convenience, so a new IPv6 address automatic configuration mechanism needs to be established for 6LoWPAN wireless sensor networks;
