Abstract: Systems and methods for efficiently allocating beacon slot among multiple nodes on multiple levels within a power line communication network are described. In various implementations, these systems and methods may be applicable to Power Line Communications (PLC). For example, a method may include performing, by a communications device, assigning beacon transmission times to nodes within the communication device's network. The assigned beacon transmission times comprise a beacon slot and frame pattern. The beacon slot and frame pattern ensure that each node does not transmit a beacon in a beacon slot that is adjacent to a beacon slot assigned to a parent or child node. A beacon transmission slot is reserved for a base node in every frame. The frames may be organized into thirty-two-frame superframes, wherein each frame comprises a base node beacon slot and four switch node beacon slots.

Abstract: Systems and methods for implementing data concentrated initiated multicast firmware upgrade in power line communications (PLC) are described. In an illustrative embodiment, a method performed by a PLC device may include forming a group of PLC devices to receive a transmission of a data set, the group being organized according to a hierarchical structure, transmitting the data set to the group of PLC devices, determining whether a PLC device in the lowest level of the hierarchical structure is missing one or more portions of the data set, and retransmitting at least the missing portions of the data set until the lowest level of PLC devices each have the full data set.

Abstract: Embodiments of methods and systems for switch table update using demotion command in PRIME are presented. In one embodiment, the method is performed by a power line communication (PLC) device. For example, the PLC device may be a data concentrator. In such an embodiment, the method may include receiving a request for registration from a node in a PLC network. The method may also include determining whether the node was previously included in the network according to an alternate network topology configuration. Additionally, the method may include issuing a notification to a group of switch nodes in the network instructing the switch nodes to update respective switch tables in response to a determination that the node was previously included in the network according to an alternate network topology configuration.

In some embodiments, a method may include transmitting a one-hop broadcast request message to a plurality of PLC devices in a mesh network and receiving a response from each of the devices. The method may also include selecting one of the devices as a bootstrapping agent, sending a join request to a bootstrapping server through the bootstrapping agent, and, in response to successfully joining the network, setting the bootstrapping agent as a next hop toward a bootstrapping server. In another embodiment, a method may include maintaining a routing table for a plurality of PLC devices in a mesh network, receiving a join request from a PLC device, accepting the request, and updating the table to add a record corresponding to the PLC device; the record setting the bootstrapping agent as a penultimate hop toward the PLC device.
