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.
