Embodiment Construction

[0030] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] figure 1 It is a flow chart of the multi-path transmission method of the 6LoWPAN network. In the 6LoWPAN network, when the source node sends a message, it first determines the number of paths required to transmit the message, and then assigns one or more paths to each parent node through the Rank value. The Rank value is calculated by its parent node according to its own remaining energy value and the hop value to the sink node, and the number of paths is encapsulated in the multi-path header of the message at the adaptation layer, and sent to the parent node corresponding to the Rank value , each intermediate routing node forwards the message according to the above method until it is sent to the sink node.

[0032] The method specifically includes the following steps:

[0033] S1. After receiving the message from the upper layer o...

Abstract

The invention relates to an IPv6 wireless sensor network multipath transmission method based on an RPL routing protocol and belongs to the technical field of a wireless sensor network. According to the method, in a 6LoWPAN wireless sensor network based on an IPv6 technology, through utilization of the RPL protocol, a father node set generated when routing is carried out is established according to a hop count value from a source node to a sink node and node residual energy, a message is copied to obtain multiple copies according to a reliability demand of a message and a Rank value of the father nodes, and the message copies are distributed to a plurality of RPL father nodes for forwarding. According to the method, in order to enable the 6LoWPAN wireless sensor network to support multipath message transmission, a new 6LoWPAN head--a multipath head is designed in an adaption layer, and the multipath head is used for copying the message to multipath transmission and finally eliminating the message. According to the method, through increase of redundant paths when the message is transmitted, the message transmission reliability in the network can be improved; and when transmission paths are selected, the node residual energy and the hop count from the source node to the sink node are taken into consideration, so the life time of the network can be effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor networks, and relates to an IPv6 wireless sensor network multipath transmission method based on the RPL routing protocol. Background technique [0002] Wireless sensor networks have always been regarded as current international research hotspots, and are one of the core research contents of the Internet of Things technology. aspect. [0003] The introduction of IPv6 technology to the wireless sensor network can make each sensor node have a unique IPv6 address, realize the IP communication between the node end and the host end, and successfully extend the application on the Internet to the wireless sensor network. Moreover, the 6LoWPAN network that combines wireless sensor networks with IPv6 technology has high popularity and applicability, and more address space meets the needs of deploying large-scale, high-density and low-speed wireless personal area network devices. However, because t...
