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;

Embodiment 1

[0202] Based on the simulation parameters in Table 1, this embodiment simulates the method in the present invention, and the performance analysis is as follows: with the increase of the transmission range, the cost of obtaining the address by the cluster head node through the initialization process tends to be constant, and the cost of obtaining the address by the full-featured new node The penalty increases with the transmission range. The nodes in the cluster obtain the address from the cluster head node, so the address cost and delay tend to be constant. In the next generation wireless sensor network, the average cost of each cluster head node to obtain an address is 4, the average cost of each cluster head node to obtain an address is 3, and the average delay of each cluster head node to obtain an address is 35ms. The average delay for a node to obtain an address is 30ms.

Abstract

The invention provides a method for achieving a next-generation wireless sensor network route. The wireless sensor network comprises four nodes including an access router, a cluster head node, a cluster-in node and a new node. One wireless sensor network only comprises one access router and has access to the Internet through the access router. The cluster head node is a global-function node obtaining the IPv6 address, the cluster-in node is a partial-function node obtaining the IPv6 address, and the new node is a global-function node or a partial-function node not obtaining the IPv6 address. If the new node is the global-function node, namely the new global-function node, is in the one-hop range of one cluster head node and has no new neighbor node which is the global-function node, namely the new partial-function node, the new node is changed into a dormant state. The route can be automatically achieved through an address tree, route data do not need to be stored, and the route setup process is not needed, so that the routing efficiency is improved, the routing delay is reduced, and the communication quality is improved.

Description
