Abstract: An apparatus for a power line communication network includes a power line transmitter/receiver, a processor coupled to the power line transmitter/receiver, and memory accessible to the processor. The processor is configured to store a routing table in the memory for routing packets in an upward direction towards a data concentrator (DC). However, no routing table is provided for routing packets in a downward direction away from the DC. Instead of using a routing table to route packets in the downward direction, the processor is configured to employ source routing in the downward direction.

Abstract: Method and apparatus for avoiding hidden node collisions in a communication network. A network communication device includes a packet transmitter. The packet transmitter is configured to subdivide a packet to be transmitted via a communication network into a plurality of segments based on the packet exceeding a predetermined maximum size, and to sequentially transmit the segments via the communication network. The packet transmitter is also configured to construct an acknowledgement packet responsive to reception of each segment of a packet received via the communication network. The acknowledgement packet includes a field indicating whether an additional segment of the packet is to be transmitted via the communication network. The packet transmitter is further configured to transmit the acknowledgement packet via the communication network.
