With reference to fig. 2, an embodiment of the present disclosure provides a method for power line carrier communication transmission, including:
and S21, the central node receives the transmission request signaling sent by the communication node, and calculates the route between the central node and the communication node.
In the embodiment of the present disclosure, after receiving a transmission request signaling sent by a communication node, a central node performs a route calculation operation according to a control word, an identifier or other information used for indicating a signaling type included in the transmission request signaling.
Optionally, the transmission request signaling comprises information for indicating a signaling type.
In the embodiment of the present disclosure, the information for indicating the signaling type included in the transmission request signaling is configured to, after the central node receives the transmission request signaling, perform a corresponding operation according to the information for indicating the signaling type, that is, calculate a route between the central node and the communication node.
In practical applications, the information for indicating the signaling type may be in the form of identification bits, such as 00, 01, 10 or other identifications, or in the form of decoding, such as 01111110, 01111111, 11011110 or other decoding forms. The present application is not limited to this specifically, and may be set according to an actual working condition, as long as the indication signaling type can be reflected, and the corresponding node executes the corresponding operation when receiving the information including the indication signaling type. It should be understood that the information indicating the type of transmission request signaling is in the same form as the other information indicating the type of signaling or instruction, and is different in content so that the corresponding types of signaling or instruction can be distinguished.
Optionally, calculating a route between the central node and the communication node includes:
calculating a link effective factor and reliability of a network link;
determining a network effective topology set according to the link effective factors;
and determining the routing of the central node and the communication node according to the determined effective topology set and the reliability.
In the disclosed embodiment, the link effectiveness factor of a network link may be calculated according to the following equation:
wherein, the first and the second end of the pipe are connected with each other,ρ link_ij is the link-efficiency factor of the network link,Kfor the number of times the link has failed,T k is a link ofkThe duration of the secondary failure is such that,Ttime period calculated for link quality.
In practical application, if the link effective factor of a network link is 1, the corresponding link is considered as a high-reliability link.
In the disclosed embodiment, the reliability may be calculated according to the following equation:
V ij =(ρ link_ij ∫ T t0[α t (S t -S thr )]dt)/(T* MAX(S t -S thr ))
wherein the content of the first and second substances,V ij in order to be reliable in the future,S t is composed oftLink of time of daylink_ijThe signal-to-noise ratio of (c),S thr is a linklink_ijThe signal-to-noise ratio threshold for communication can be stabilized,α t is a linklink_ijThe reachability factor of (c).
In the practical application of the method, the material is,S t greater than or equal toS thr When the temperature of the water is higher than the set temperature,α t is 1, otherwiseα t Is 0. That is, in the case that the signal-to-noise ratio is greater than or equal to the signal-to-noise ratio threshold value of the link stable communication, the link is considered to be reachable, otherwise, the link is considered to be unreachable.
In the embodiment of the present disclosure, determining the network effective topology set according to the link effective factors may be understood as reserving high-reliability links according to the link effective factor calculation result, and forming a set of the high-reliability links into the network effective topology set.

and under the condition that the calculation is unsuccessful, adding the maximum link effective factor which is not added into the effective topology set, and calculating the route from the central node consisting of the effective topology set to the communication node by taking the reliability as the link weight.
In practical application, the reliability is used as the link weight to calculate the routing from the central node to the communication node, and the algorithm conforming to the greedy idea is adopted to realize the routing. If there are nodes v1, v2, v3, and v4, taking v1 as a communication node and v3 as a central node as an example, the reliability in the effective topology set may be: the reliability of the node v3 sent by the node v1 is 12, the reliability of the node v2 sent by the node v1 is 1, the reliability of the node v2 sent by the node v3 is 9, the reliability of the node v4 sent by the node v2 is 3, and the reliability of the node v4 sent by the node v3 is 4. Therefore, the shortest path to reach v3 with v1 as the starting point should be v1 to v2 to v4 to v 3. In this case, the calculated route is determined as the center node and the correspondent node route.
In practical applications, if the reliability of the effective topology set is: the reliability of the node v2 sent by the node v1 is 5, and the reliability of the node v4 sent by the node v2 is 8. According to the existing effective topology set, the route from v1 to v3 cannot be calculated, at this time, if the link effective factor sent by the node v2 to the node v3 is the largest of the link effective factors which are not added to the effective topology set, the node v2 is sent to the node v3 to be added to the effective topology set, and then the shortest path from v1 to v3 can be calculated to be from v1 to v2 to v 3. In this case, the calculated route is determined as the center node and the correspondent node route.
And S22, the central node sends a route configuration signaling to the communication node along the route, wherein the route configuration signaling is used for setting parameters of the passing route nodes.
