A Routing Method for Adaptive Blind Relay

Abstract

The invention discloses a routing method for self-adaptive blind relay, which includes: S1, each node in the network first monitors the detection frame, and then selectively sends periodic detection frames according to the monitoring situation of the detection frame; S2, the nodes in the network Adaptively form a relay role according to the received interception detection frame; S3, the relay role arranges forwarding according to the blind relay control information in the frame header of the received data frame; S4, each node in the network listens And record the blind relay control information of the frame header of the data frame of the receiving node, so as to flexibly adjust the blind relay control information of the frame header of the data frame sent by itself. The routing method of the adaptive blind relay of the present invention can use the network detection frame to form the relay role adaptively, and adjust the forwarding of the relay node in the transmission path through the blind relay control parameter in the frame header, so that the power line can be improved. The communication efficiency of the carrier communication network can avoid the risk of potential network congestion.

Problems solved by technology

In various ubiquitous power Internet of Things applications, there are common problems such as large number of nodes, complex network structure, and large interference in the communication environment, which often lead to unstable communication efficiency in the power Internet of Things.

[0003] Traditional routing methods are generally based on the routing table. In a relatively stable environment, the communication performance is generally relatively stable. However, in a complex and time-varying environment, due to the rapid change of the network structure, the network frequently updates and repairs the routing table. , resulting in a great change in the communication effect

In addition, although the general blind relay routing method does not require a routing table, each node often participates in forwarding. In a scenario with a small number of nodes, the communication effect is often relatively stable, but when the number of nodes is large, due to the number of nodes participating in forwarding The surge may lead to network congestion within a certain period of time, and even in extreme cases, it will trigger a network storm and cause network paralysis
