Fiber-wireless for smart grid: A survey [PDF]
EPJ Web of Conferences, 2017 Smart grid allows two-way communication between power utility companies and their customers while having the ability to sense along the transmission lines. However, the downside is such, when the smart devices are transmitting data simultaneously, it results in network congestion.
