As shown in fig. 2, an embodiment of the present disclosure provides a method for power 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 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 specifically limited to this, 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 a corresponding operation when receiving 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 signaling or instruction types can be distinguished.

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 content of the first and second substances,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 first and the second end of the pipe are connected with each other,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 embodiment of the present disclosure, determining the network effective topology set according to the link effective factor may be understood as calculating a result according to the link effective factor, reserving the high-reliability links, and forming the set of the high-reliability links into the network effective topology set.

Therefore, the shortest path to v3 starting from v1 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 in the effective topology set is: the reliability degree of the node v2 sent by the node v1 is 5, and the reliability degree of the node v4 sent by the node v2 is 8. The route from v1 to v3 cannot be calculated according to the existing effective topology set, at this time, if the effective factor of the link sent by the node v2 to the node v3 is the largest of the effective factors of the links 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.
