In this chapter, an introduction of communication networks and relaying strategies for SGs is presented, together with a discussion of how to improve spectral efficiency and coverage in relay-based ICT infrastructure for SG applications. Considering communication channel medium, there are two sets of networks in SGs, i.e., wired and wireless communication networks. Special attention is paid to the use of various relaying strategies in power line communication (PLC) and wireless communication networks.
