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.
Abstract:
Systems and methods for routing protocols for power line communications (PLC) are described. In some embodiments, a method performed by a PLC device, such as a PLC meter, may include identifying at least one bootstrapping agent and a personal area network (PAN) identifier for one or more networks that are operating within a personal operating space of the PLC device. The device selects a target bootstrapping agent to use for the join process with a target network. The target bootstrapping agent may be selected from a list of bootstrapping agents associated with the target PAN identifier. If the attempt to join the target network fails, then the device further determines if other bootstrapping agents are associated with the target PAN identifier. The device selects an alternate target bootstrapping agent from the other bootstrapping agents that are associated with the target PAN identifier and reattempts the join process.
Abstract:
A radio communications device includes a RTC configured to run even during sleep for receiving from a coordinator node (CN) in an asynchronous channel hopping WPAN an asynchronous hopping sequence (AHS) frame that includes the CN's hopping sequence. A processor implements a stored sleepy device operation in asynchronous channel hopping networks algorithm. The algorithm is for determining a time stamp for the AHS frame and the CN's initial timing position within the hopping sequence, storing the time stamp, going to sleep and upon waking up changing a frequency band of its receive (Rx) channel to an updated fixed channel. A data request command frame is transmitted by the device on the CN's listening channel that is calculated from the CN's hopping sequence, time stamp, CN's initial timing position and current time, and the device receives an ACK frame transmitted by the CN at the updated fixed channel of Rx operation.
Abstract:
Disclosed embodiments include a network device having a split network stack that includes a physical (PHY) layer associated with first and second media access control (MAC) protocol sublayers, a processing device, and memory storing instructions that, when executed by the processing device, cause the processing device to select a route through the split network stack that includes one of the first and second MAC protocol sublayers but not the other one of the first and second MAC protocol sublayers.
Abstract:
A communication system and method includes receiving payload data of first and second media access control (MAC) frames. A MAC-level protocol is identified in response to the indication of the selected network for each of the first and second MAC frames. The payload data of the first and second MAC frames is transmitted and/or received across respective networks transmitted using, for example, power line communications signals over a common communications medium. The common communications medium is operable for carrying signals of a plurality of networks.

Abstract:
Disclosed embodiments include a system having one or more member devices coupled to a network and a power line communication (PLC) device. The PLC device is configured to identify available bootstrapping agents that correspond to the one or more member devices, each available bootstrapping agent having a corresponding personal area network (PAN) identifier, identify a target network having a PAN identifier to join, select a target bootstrapping agent from available bootstrapping agents associated with the target PAN identifier to use for a join process with the target network, attempt to join the target network using the target bootstrapping agent, and when the attempt to join is successful, transmit and receive PLC signals over at least one power line associated with the target network using a particular frequency band and a modulation scheme.
