Abstract
Systems and methods for routing protocols for power line communications (PLC) are described. 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.
