Routing in powerline communication networks

摘要

A communication apparatus includes a plurality of communication nodes (11) that select one communication route from among a plurality of communication routes, and perform a unicast communication with a communication partner on the communication route selected; and a wire (12) that is used as a medium for supplying power to each of the communication nodes and as a communication medium between communication nodes, and connects each of the communication nodes to form a network of the communication route. The apparatus may be used as a signalling network on a railway, bridge, river etc.
