Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1a is a schematic flowchart of a network access method of a network node according to an embodiment of the present invention. The method is applicable to the deployment of the network node in large-scale wireless equipment networking, and can be executed by a network access device of the network node, wherein the network access device can be composed of hardware and/or software and can be generally integrated in wireless communication equipment. The method specifically comprises the following steps:
and S110, detecting whether a relay node exists around the node.
In this embodiment, the Relay node may be a node having a Relay function, and is also referred to as a Relay node. The network obtained by using the node network access method of the embodiment may at least include two nodes, namely a Relay node and a common node.
In the prior art, in a large-scale networking application scene based on the bluetooth low energy Mesh, the Relay node can be selected in a manual designated mode, but the flexibility of the network is greatly reduced, and when the Relay node fails or the Relay node is moved out of the network, the network fails. The large-scale high-density network refers to a device in which a large number of devices exist in a one-hop range of each device, but when the range of the whole network exceeds the range which can be covered by a single device, data can be transmitted to other nodes in the network range through more than one-hop transmission.
Based on the current situation, in the process of carrying out large-scale intensive networking based on the low-power-consumption Bluetooth Mesh, a method is needed for realizing automatic deployment and updating of Relay nodes in the low-power-consumption Bluetooth Mesh network, so that the deployment of the Relay nodes is more suitable for the current network state, the influence of network flooding on data packet transmission is reduced, the network is more robust and stable, and meanwhile, the network topology can be dynamically adjusted according to the current network state and the position of a real node, and the network robustness is improved.
In order to implement the above functions, in this embodiment, after the bluetooth low energy Mesh node completes the network access process, each network access Mesh node needs to determine whether a Relay function needs to be started. Specifically, whether a Relay node exists around the node needs to be detected, and whether the Relay function of the node is started is considered if the Relay node does not exist.
Optionally, detecting whether a relay node exists around the node includes: monitoring heartbeat packets sent by relay nodes around the node; if the received heartbeat packet is determined and the received signal strength indication RSSI corresponding to the heartbeat packet is greater than a first set threshold value, determining that a relay node exists around the node; otherwise, determining that no relay node exists around the node.
For example, after the Mesh node is networked, it may be first monitored whether a Relay node is periodically sent to the heartbeat packet. After determining the Relay role of each Relay node, each Relay node broadcasts a heartbeat packet periodically. If the heartbeat packet is not received, determining that no Relay node exists around the Mesh node, and starting a Relay function starting process by the Mesh node; if a heartbeat packet is Received, the newly added Mesh node can continuously judge whether the Received RSSI (Received Signal Strength Indication) of the Relay heartbeat packet meets a set threshold value, namely a first set threshold value, wherein the first set threshold value is an RSSI minimum value, and if the RSSI of the Received heartbeat packet is less than or equal to the threshold value, the Relay node can be considered to be far away from the Mesh node, and the Mesh node can still start a Relay function starting process by itself; if the RSSI is larger than the first set threshold, the Relay node is near the Mesh node, and the Relay node around the Mesh node can be determined without starting the Relay function of the Relay node.
In this embodiment, the heartbeat packet sent by the Relay node has two functions: one is to represent the existence of the self, and is convenient for the Mesh nodes of the peripheral network to search the self; the other function is that when the peripheral nodes cannot search the heartbeat packet of the Relay node within a certain time interval, the peripheral nodes can automatically start a real function starting process to compete to become the Relay node, and therefore robustness and stability of the network are maintained.
Optionally, after detecting whether a relay node exists around the node, the method further includes: when the node accesses the network, if the relay node is determined to exist, the address of the relay node is cached, and the relay node is used as a target relay node when the node sends data.
For example, when a Mesh node accesses a network, if the Mesh node detects that a Relay node exists around the Mesh node, the Mesh node caches an address of the Relay node, and preferentially sends data to the Relay node when sending the data.
Optionally, detecting whether a relay node exists around the node includes: and under the condition that the node is accessed to the network, periodically detecting whether a relay node exists around the node.
Correspondingly, after detecting whether the relay node exists around the node, the method further comprises the following steps: and if the relay node is determined to exist, keeping the function of the node unchanged.
For example, in order to improve network stability and increase network flexibility, in this embodiment, when a Mesh node is already networked, dynamic update of a Relay node may be implemented by periodically detecting whether a Relay node exists around the Mesh node. Specifically, because the Relay node can be maintained according to the heartbeat packet, if the Mesh node can periodically receive the heartbeat packet sent by the Relay node, which indicates that there are Relay nodes around the Mesh node at this time, the current function of the Mesh node can be kept unchanged, that is, the Relay function of the Mesh node is not started, and when the Mesh node cannot receive the heartbeat packet sent by the Relay node, the Mesh node can randomly retreat for a period of time, that is, wait for a period of time, and then select and determine the Relay node again.
And S120, if the relay node does not exist, starting a relay function starting process of the node, and monitoring whether other nodes which start the relay function starting process exist around the node in a preset time period.
In this embodiment, if the peripheral Relay node cannot be detected, that is, it is determined that there is no Relay node, the Relay function starting process of the node may be started to start the Relay function of the node, and meanwhile, to avoid that the Relay function is started when each Mesh node simultaneously enters the network, the distribution of the Relay nodes in the network is more uniform and reasonable, and while the Mesh node starts the Relay function starting process, it may be monitored whether there are other nodes around the node that compete for the Relay function with the node, that is, other nodes that have started the Relay function starting process.
Optionally, starting the relay function starting process of the node includes:
and after randomly retreating for a period of time, broadcasting and sending a relay function starting notice to the peripheral nodes.
The purpose of broadcasting the Relay function starting notification is to announce the node to start the Relay function to the peripheral nodes, and avoid the Relay function from being repeatedly started by other peripheral nodes which access the network simultaneously, so that the distribution of the Relay nodes in the network is more reasonable.
The advantage of performing random backoff is that the nodes accessing the network simultaneously can transmit the Relay function start notification in a staggered manner, so as to prevent the problem that other nodes in the periphery of the nodes accessing the network simultaneously transmit the Relay function start notification to the node, which results in infinite competition for Relay function among the nodes.
Optionally, monitoring whether there are other nodes that have started the relay function starting process around the node within a preset time period includes: monitoring relay function starting notifications sent by other nodes around the node in a preset time period; if the relay function starting notification is determined to be received and the RSSI corresponding to the relay function starting notification is larger than a second set threshold, determining that other nodes starting the relay function starting process exist around the node; otherwise, determining that other nodes starting the relay function starting process do not exist around the node.
Optionally, after monitoring whether there are other nodes that have started the relay function starting process around the node within a preset time period, the method further includes: and if other nodes which start the relay function starting process exist, randomly retreating for a period of time, and returning to re-detect whether relay nodes exist around the node.
For example, if it is determined that there is no Relay node, the Mesh node may start a Relay function opening process after randomly retreating for a certain time, that is, send a Relay function opening notification to the peripheral device, where the Relay function opening notification may be, for example, a real opening broadcast packet. Specifically, after sending a Relay start broadcast packet, a Mesh node defaults to perform scanning operation within a period of time so as to determine whether the periphery has the same function of competing for starting the Relay by the Mesh node, and if the Mesh node receives a real start broadcast packet from the periphery node during a scanning window period and the RSSI of the broadcast packet meets a threshold condition, namely a second set threshold, the Mesh node proves that the periphery node competes for the Relay function at the same time, and at the moment, the Mesh node can back off for a period of time randomly, return to re-detect whether a Relay node exists at the periphery of the Mesh node, and re-execute the flow; if the Mesh node does not receive a Relay opening broadcast packet sent by another node during the scanning window, it indicates that the peripheral node does not open the Realy function, the node successfully competes, and the Realy function of the node can be opened at this time.
And S130, if it is determined that other nodes starting the relay function starting process do not exist around the node, starting the relay function of the node.
In this embodiment, if it is determined that there is no other node in the periphery of the node that has started the relay function starting process, it indicates that the peripheral node has not started the Realy function, and the node successfully competes, and at this time, the Realy function of the node may be started. Specifically, after formally starting the real function, the node may broadcast and send a heartbeat packet to the peripheral nodes to indicate its existence.
In this embodiment, when each node accesses the network, it is first determined whether there is a Relay node around the node, and then the Relay function is started according to the method provided in this embodiment, so that the Relay nodes are reasonably distributed in the network as the network scale increases. In addition, adjacent Relay nodes can mutually buffer the address of the other side to serve as the destination address of data transmission in multi-hop transmission, so that the data can be only transmitted to the corresponding Relay nodes when the data is forwarded between the Relay nodes, flooding data transmission is avoided, and data redundancy in network transmission is reduced.
Fig. 1b shows a schematic diagram of a large-scale high-density networking implemented by the node network access method provided in this embodiment, where a node labeled with an "R" word is a node with a Relay function, namely, a Relay node 1, automatically selected by the method provided in the present invention during the network access process of each node, and other nodes not labeled with an "R" word are nodes with a non-Relay function, namely, common nodes 2. The distribution quantity of Relay nodes increases along with the continuous increase of the network scale, but each common node is covered by at least one node with the Relay function, so that each node can send or receive information to the node outside the hop range of the node, and the automatic selection function of the Relay nodes is realized.
According to the technical scheme of the embodiment, whether the relay node exists around the node is detected, if the relay node does not exist, the relay function starting process of the node is started, whether other nodes which start the relay function starting process exist around the node is monitored in a preset time period, and if the relay function of the node is started, the relay function of the node is started. The method and the device utilize the advantage that the nodes dynamically enable the relay function according to the current network state, solve the problem that the network flexibility is limited due to the fact that the relay function is directly started on each network access node or the relay nodes need to be manually selected in the prior art, and achieve the effect of improving the network flexibility.
Example two
Fig. 2a is a schematic flowchart of a network access method of a network node according to a second embodiment of the present invention. The present embodiment provides a preferred network node network access method by optimizing based on the above embodiments. The method specifically comprises the following steps:
s201, whether the node is accessed to the network or not is judged, if yes, S203 is executed; if not, go to S202.
S202, continuing to wait for joining the network.
S203, whether heartbeat packets sent by relay nodes around the node are sensed or not is judged, and if yes, S204 is executed; if not, go to S206.
S204, whether the RSSI corresponding to the heartbeat packet is larger than a first set threshold value or not is judged, if yes, S205 is executed; if not, go to S206.
S205, caching the address of the relay node, and taking the relay node as a target relay node when the relay node sends data.
S206, after randomly retreating for a period of time, broadcasting and sending a relay function starting notice to the peripheral nodes, and monitoring the relay function starting notices sent by other nodes around the node in a preset time period.
S207, whether a relay function starting notice sent by other nodes around the node is sensed or not in a preset time period, if yes, S208 is executed; if not, go to S210.
S208, whether the RSSI corresponding to the relay function starting notice is larger than a second set threshold value or not is judged, if yes, S209 is executed; if not, go to S210.
S209, randomly back off for a period of time, and returns to execution S203.
And S210, starting the relay function of the node, and broadcasting and sending the heartbeat packet to the peripheral nodes.
According to the technical scheme of the embodiment, on the basis of the embodiment, whether the relay function needs to be started around the node is determined by monitoring the heartbeat packet, and when the relay function is started, whether the node competes for the relay function is determined by monitoring the relay function starting notice sent by other nodes around the node, so that the relay function of the node is formally started when the relay function competes for the node is determined, the problem that in the prior art, the network flexibility is limited due to the fact that each network access node directly starts the relay function or needs to manually select the relay node is solved, and the effect of ensuring the reasonability of the distribution of the relay nodes in a dynamic network is achieved while the network flexibility is improved.
Based on the networking method provided by the foregoing embodiments, a typical data transmission process is enumerated as follows, as shown in fig. 2B, where nodes with "R" word are Relay nodes, such as a node B, a node C, a node D, a node E, a node F, and a node G; nodes without the word "R" are normal nodes, such as a nodes, I nodes, and H nodes. The method specifically comprises the following steps:
1) the node A finds a nearby node B as a preferred Relay node according to the network access method of the network node provided by the embodiment, and the node I also finds a node F and a node G as Relay nodes;
2) when the node A sends data to the node I, the data is firstly sent to the node B, the node B waits for the response information of the peripheral common nodes after broadcasting once, but the node I is positioned outside the one-hop range of the node B, so the node B cannot receive any response message sent by the node I after waiting for a certain time, and the following steps are continuously executed;
3) and the node B continuously forwards the data packet to peripheral Relay nodes, forwards the data to the peripheral Relay nodes, for example, the node E repeats the operation similar to the step 2), and then forwards the data to the node F again. Of course, the node B may also send the data to the node C, and then the node C forwards the data to the node D, which is not described herein again;
4) the I node is in the coverage range of the F node with the Relay function, so that the F node receives a response message sent by the I node after carrying out data broadcasting for one time;
5) when the I node replies the response message to the A node, the I node follows the similar operation of the steps, except that when the response message is transmitted to the node which does not participate in the data packet transmission path, the node does not do any processing and directly discards the response message, for example, if the data is transmitted to the node I by the path of the B node, the E node and the F node, the D node discards the response message when the response message is transmitted from the F node to the D node;
6) when the A node receives the response message of the I node, a typical data transmission operation is completed.
To sum up, it needs to be pointed out that the forwarding of data between Relay nodes is sent by broadcasting, that is, a Relay node will forward data to all its neighboring Relay nodes, and if a Relay node receives repeated data, it can directly discard the repeated data, so as to avoid the occurrence of a large amount of repeated data in the network. In addition, the principle of alternative transmission is followed from the common node to the Relay node, that is, the common node may select one Relay node of at least one Relay node cached by the common node as a target Relay node for data transmission.
