Description

Agent change evaluation method and device for high-speed power line carrier communication network
Technical Field
The invention relates to the technical field of power network communication, in particular to a proxy change evaluation method and device for a high-speed power line carrier communication network.
Background
The Routing protocol of the wireless self-organizing network can be divided into two categories of prior type table driving protocol and reactive type On-Demand Routing protocol (Ad-hoc On-Demand Vector Routing, AODV), in a mechanism of the prior type table driving protocol, each network station maintains a Routing information table to all known destination stations, the Routing table is updated according to the triggering of periodic or network topology change events, when the stations need to send data packets, Routing information which can reach the destination stations is searched from the Routing table maintained by the stations, and the mode needs to consume network transmission bandwidth resources to maintain the Routing table; in the AODV mechanism, a site searches or establishes a route to a destination site only when data needs to be transmitted, and although periodic exchange of a link or a topology state is not required, a possibly huge routing table does not need to be maintained, thereby saving bandwidth, the time for establishing the route may be very long.
In order to shorten the establishment time of the route and save resources, a common mode at present is to use a High speed Power Line Communication (HPLC) link layer technology, which may include two mechanisms of table-driven routing and on-demand routing in a specification, and defines a hybrid mechanism with table-driven routing as a main mechanism and on-demand routing as an auxiliary mechanism. The table-driven routing is embodied in that a Central Coordinator (Central Coordinator, CCO) establishes and maintains a global routing table reaching all network stations by means of information carried in a discovery list message, a Station (Station, STA) association request message, an association confirmation message, a Proxy Station (PCO) change request message and a PCO change request confirmation message so as to update the PCO stations; in addition, in the using process, the stations can be controlled to transmit the detection data packets aperiodically, and the neighbor station information is acquired according to the received discovery beacons periodically transmitted by the neighbor stations, so that the probability of transmitting the duplicate heads is avoided, and the control overhead is saved.
However, the currently used method has the following technical problems: because the notification reminding is only carried out in a message transmission interaction mode in the updating process, the interactive messages are easy to be falsified, the updating error is caused, the accuracy and the effectiveness of the routing table are reduced, and the communication efficiency and the reliability of the whole network are further reduced.

In order to solve the above problem, the proxy change evaluation method for a high-speed power line carrier communication network according to the embodiments of the present application will be described and explained in detail by the following specific embodiments.
Referring to fig. 1, a flowchart of an agent change evaluation method for a high-speed power line carrier communication network according to an embodiment of the present invention is shown.
In one embodiment, the method is applied to a Central Coordinator (CCO). The central Coordinator can be connected with a plurality of stations (Station, STA) and a plurality of Proxy stations (PCO), and the CCO and the PCO have a packet forwarding function, and the STA can only send packets to other stations and cannot perform a relay forwarding function.
As an example, the agent change evaluation method for a high-speed power line carrier communication network may include:
and S11, after the HPLC networking is finished, periodically counting the PCO and reporting the communication success rate between the PCO and the child station.
After networking of the communication network is completed, the site or the proxy site can determine the communication success rate between the site and each substation, and can periodically send the communication success rate between the site and each substation to the CCO to determine whether node change is needed.
As an example, step S11 may include:
and a substep S111, after the HPLC networking is finished, the PCO forms a communication success rate report CCO by counting the uplink communication success rate and the downlink success rate between the PCO and the substation points and summarizing.
Specifically, the PCO may count the success rate of uplink communication and the success rate of downlink communication between itself and each substation, and periodically report the counted success rate to the CCO in real time, so that the CCO determines whether a node change is required.
And S12, in the dynamic route maintenance process, each stage of station receives the proxy beacon or the discovery beacon of the neighbor station in the beacon time slot.
After the networking of the communication network is finished, the maintenance of the network routing table depends on the discovery list message and the beacon frame, and all levels of stations receive the discovery list message and the beacon frame of the neighbor stations, so that better PCO can be selected by judging the conditions of receiving the discovery list message and the beacon frame of the neighbor stations and the change conditions of the neighbor stations.
As an example, step S12 may include:
substep S121, after networking is completed, each stage of station receives the proxy beacon or discovery beacon of the neighboring station in the beacon slot, and determines the channel quality of the surrounding stations according to the condition of receiving the beacon frame.
Specifically, the stations or the proxy stations may each acquire the channel quality of each of the adjacent stations or proxy stations.
And S13, the PCO or the STA detects a new alternative proxy station by combining the received discovery list message.
In one embodiment, after determining the channel quality between the PCO or the STA and each of the child sites, the PCO or the STA may screen the communication channel with the best channel quality from the plurality of channel qualities, so as to detect a new candidate proxy site according to the communication channel with the best channel quality.
As an example, step S13 may include:
and the sub-step S131, the PCO or the STA judges whether the neighbor station can become a new alternative proxy station according to the condition of receiving the beacon frame and the discovery list message sent by the neighbor station.
Substep S132, if the PCO or STA receives the proxy beacon sent by the neighbor station and the neighbor station is included in the discovery list message received by the PCO or STA, the neighbor station becomes a new candidate proxy station for the PCO or STA.
Substep S133, otherwise, the neighbor station cannot become a new candidate proxy station for the PCO or STA.
Specifically, it may be determined whether an agent beacon sent by an adjacent station is received, if yes, it is determined whether the adjacent station is in the list message, and if yes, it is determined that the adjacent station may become a new candidate agent station; and if the agent beacon sent by the adjacent station is not received or the adjacent station is not in the list message, determining that the adjacent station cannot become a new alternative agent station.
And S14, if the PCO or the STA detects a new alternative proxy site, carrying out change evaluation on the new alternative proxy site.
After determining the new candidate agent site, a change evaluation needs to be performed on the new candidate agent site to determine whether to perform a start agent site change process.
As an example, step S14 may include:
and a substep S141, judging the channel quality between the PCO or STA and the new candidate proxy station, and judging the communication success rate between the PCO or STA and the current proxy station.

And S15, if the change evaluation is that the change evaluation condition is met, the PCO or the STA starts an agent change process and initiates an agent change request to the CCO.
If the channel quality and the communication success rate are determined to meet the requirements in the change evaluation, the change parameters are determined to meet the preset conditions, and a change process can be started.
Specifically, an agent change request may be generated and sent to the CCO.
As an example, step S15 may include:
and a substep S151, if the new candidate proxy station meets the proxy station change evaluation condition, evaluating a new proxy station by the PCO or the STA.
And a substep S152, the PCO or the STA initiates an agent change request to the CCO by sending an agent change request message.
In actual operation, the PCO or the STA may generate a corresponding change packet and send the change packet to the CCO, thereby initiating an agent change request to the CCO.
And S16, if the change evaluation is that the change evaluation condition is not met, updating the standby proxy site list of the PCO or the STA.
When the change evaluation is determined not to be in accordance with the change evaluation condition, the standby proxy site list of the PCO or the STA may be updated to facilitate subsequent changes.
As an example, step S16 may include:
substep S161, saving and updating the new candidate proxy site to a standby proxy site list of the PCO or STA, wherein each data entry of the standby proxy site list includes a site identifier and a lifetime value i;
substep S162, traversing the standby agent site list;
substep S163, if the new candidate agent site is the saved site of the list of standby agent sites, the site identifier of its data entry is not changed and the lifetime value i isT+1＝iT+1, wherein, iTIs the value of the lifetime at the last cycle T, iT+1The life cycle value of the current period T + 1;
substep S164, if the new candidate proxy station is not stored in the standby proxy station list, creating a new data entry in the standby proxy station list, where the station identifier is set to the identifier of the new candidate proxy station in the discovery list message received by the PCO or STA, and the lifetime value i is set to the identifierT+1＝iT+1, wherein, iT＝0，iT+1＝1。
Optionally, the lifetime value may be adjusted according to actual needs.
Referring to fig. 2, an operation flowchart of a proxy change evaluation method for a high-speed power line carrier communication network according to an embodiment of the present invention is shown.
In actual operation, the success rate of data packet statistics communication can be sent in a contention channel, then an agent or a discovery beacon is received in a beacon time slot, then whether a new agent station is detected or not is determined, if the new agent station is not detected, the step of sending the success rate of data packet statistics communication in the contention channel is returned again, if the new agent station is detected, whether the agent station meets the change requirement or not is evaluated, if the new agent station meets the change requirement, an agent station change request is sent to a CCO, and if the new agent station does not meet the change requirement, a standby agent station list is updated and stored.
