The traditional energy grid allows for one-way communication of energy usage between customers and utilities. This does not allow utilities to control or to suggest any changes in the consumption based on the obtained energy data. In this book, we design and implement innovative secure and reliable two-way communication between homes and the Utility. In this context, different houses communicate their energy usage, while an electric transformer relays action requests from the energy utility's...
