Problems solved by technology

This routing node network access method has the problems of high human resource consumption, low network access efficiency, and high channel configuration error rate due to manual channel configuration. It is also necessary to re-configure the channel manually, which makes the network switching and re-entry efficiency of routing nodes extremely low, and the overall network access flexibility is not high

Abstract

The invention provides a channel switching based network accessing method and device which are applied to a routing node. The method comprises broadcasting and sending a DIS message in a current channel according to a preset time interval; monitoring whether a DIO message corresponding to the DIS message is received; judging whether a DIO message is received in a broadcast time period in which thenumber of message broadcast times is not greater than the number of preset broadcast times according to the DIO message monitoring result; if a DIO message is received in the broadcast time period, aDAO message is sent to a root node in a wireless network corresponding to the DIO message so as to access the wireless network; if the DIO message is not received in the broadcast time period, switching the current channel and jumping to broadcast and send the DIS message to continue execution. The method can automatically switch the current channel according to the actual network environment ofthe routing node, so as to access the wireless network based on a proper channel. The manpower consumption is reduced, and network accessing flexibility, accuracy and efficiency are improved.

Description

technical field [0001] The present invention relates to the technical field of RPL (Routing Protocol for Low-power and lossy networks, low-power lossy network routing protocol) routing network access, in particular to a channel switching network access method and device. Background technique [0002] The RPL routing protocol can provide a general IPv6 routing mechanism and construction framework for lossy networks with low power consumption and low speed, so that the wireless network formed by using the RPL routing protocol has good security, supports dynamic joining of nodes, and avoids loops, etc. advantage. But for now, when a routing node wants to access a certain wireless network built using the RPL routing protocol, it needs to manually configure the channel of the routing node with the same channel as the corresponding channel of the root node in the wireless network, and the Based on the manually configured channel, the routing node normally accesses the wireless ne...
