Abstract: A network includes at least one node to communicate with at least one other node via a wireless network protocol. The node includes a network configuration module to periodically switch a current node function of the node between an intermediate node function and a leaf node function. The switch of the current node function enables automatic reconfiguration of the wireless network based on detected communications between the at least one node and at least one intermediate node or at least one leaf node via the wireless network protocol.

Abstract: A network includes a parent node and at least one child node configured to communicate with the parent node via a wireless network protocol. The parent node includes a broadcast coordinator to transmit a broadcast message from the parent node to the child node at predetermined time intervals according to the wireless network protocol. A scheduler generates a scheduling packet that is communicated in the broadcast message. The scheduling packet includes a data field to instruct each child node to activate and receive data communicated from the parent node in a prescribed time slot following the broadcast message that is defined by the scheduling packet.

Abstract: In accordance with disclosed embodiments, a first power line communication (PLC) device connected to a PLC network includes channel control logic that assigns a first channel of the PLC network for transmission on a power line of PLC data packets between the first PLC device and a second PLC device connected to the PLC network and assigns a second channel of the PLC network for transmission on the power line of PLC data packets between the first PLC device and the third PLC device connected to the PLC network. The PLC device includes a transceiver that receives and transmits PLC data packets on the PLC network and which operates as a bridge device that communicates on both the first and second channels to pass PLC data packets between the second PLC device and the third PLC device.

Abstract: A network includes an access point using a first protocol and a station using both the first protocol and a second protocol. The station uses the first protocol before a first threshold and a second protocol after the first threshold. A first duration between the second threshold and the first threshold is at least of sufficient length for the station to receive one data packet from the access point and send an acknowledgment. The station transmits to the access point a current clear-to-send packet at a current time during a current exchange based on success or failure of a previous exchange during which a previous clear-to-send packet was transmitted to the access point at a previous time.

Abstract: A power line communication device connected to a power line communication network that includes a transceiver to transmit messages to a plurality of nodes on the network and to receive messages from the plurality of nodes on the network, and a processor coupled to the transceiver to evaluate received messages and generate messages to transmit. The processor, upon receiving a promotion needed message from an additional power line communication (PLC) device joining the network, is to determine whether data communication has already been established with a base node of the network, determine whether the device is already seeking promotion to be a switch node or has already been promoted to the switch node, and determine a signal quality of the received promotion needed message from the additional PLC device joining the network. Based on those determinations, the processor is to adjust a frequency at which to transmit a promotion request based on a number of promotion requests received from the plurality of other nodes on the network and a number of promotion needed messages received.
