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: A system and method for reducing transmission collisions. In one embodiment, a transmitter for communicating of a smart grid power line network includes an arbiter. The arbiter is configured to select a transmission interval during which the transmitter can transmit. The interval is selected from a plurality of available transmission intervals reserved for contending transmissions, and selected based on a level of a hierarchical network at which the transmitter is located. The interval selected is different from any interval used by a different transmitter spaced two hierarchical levels away from the level of the hierarchical network at which the transmitter is located.
