Embodiment 1
[0042] see figure 1 , Embodiment 1 of a virtual MAC method for power line communication provided in the embodiment of the present application, including:
[0043]Step 101 , when the power line communication network is a multi-protocol network, determine whether there is an intermediate node between the source node and the destination node, if so, perform step 103 , otherwise, perform step 102 .
[0044] It should be noted that there are various mainstream protocols for power line network communication MAC layer applications, such as ALOHA, CSMA, CSMA / CD, CSMA / CA, HomePlug 1.0, and HomePlug AV. Communication is not yet possible. Therefore, when the power line communication network is a multi-protocol network, the application first judges whether there is an intermediate node between the source node and the destination node, that is, whether it is a multi-hop network or a single-hop network between the source node and the destination node. 103, otherwise, go to step 102.

Embodiment 2
[0055] see figure 2 , Embodiment 2 of a virtual MAC method for power line communication provided in the embodiment of the present application includes:
[0056] Step 201 , when the power line communication network is a multi-protocol network, determine whether there is an intermediate node between the source node and the destination node, if so, perform step 203 , otherwise, perform step 202 .
[0057] Step 201 is the same as the description of step 101 in Embodiment 1, please refer to the description of step 101, and details are not repeated here.
[0058] Step 202: Re-edit the MAC protocol of the source node according to the MAC protocol of the destination node, so that the MAC protocol of the source node is the same as that of the destination node, and send the message to be sent from the source node to the destination node.
[0059] Step 202 is the same as the description of step 102 in Embodiment 1, please refer to the description of step 102, and details are not repeat...

Abstract
The invention discloses a virtual MAC method and device for power line communication, and the method comprises the steps: firstly judging whether it is a single-hop network or a multi-hop network existing between a source node and a target node when a power line communication network is a multi-protocol network, carrying out the re-editing of an MAC protocol of the source node according to the MAC protocol of the target node if the network is the single-hop network, therefore, the two can communicate; and if the current node belongs to the multi-hop network, packaging the data to be sent of the current node according to the MAC protocol of the next node, so that the current node can communicate with the next node, and continuously repeating the process, so that the data to be sent is packaged by the middle multi-layer MAC protocol and then sent to the destination node. According to the virtual MAC method, heterogeneous networking can be carried out under power communication networks with different communication protocols, the limitation that power line communication cannot carry out communication under different protocols is broken through, and therefore the technical problem that an existing power communication network cannot carry out heterogeneous networking communication under different communication protocols is solved.
Description
technical field [0001] The present application relates to the technical field of power communication, in particular to a virtual MAC method and device for power line communication. Background technique [0002] Power line communication PLC refers to a communication technology that uses power lines as the transmission medium to modulate information onto electrical signals for data transmission. This technology realizes the communication between various nodes within the power line communication network and with other communication networks. A complete power line communication transceiver is composed of physical layer, medium access control layer (MAC layer), logical link layer and so on. Among them, the medium access control layer (MAC layer) mainly completes functions such as establishing and maintaining links between transceivers, sending and receiving confirmation frames, and channel access control. Power line communication requires the application of appropriate data com...
