Abstract
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. Fiber wireless (FiWi) network is one of the best congestion solutions for smart grid up to date. In this paper, a survey of current literature on FiWi for smart grid will be reviewed and a testbed to test the protocols and algorithms for FiWi in smart grid will be proposed. The results of number of packets received and delay vs packet transmitted obtained via the testbed are compared with the results obtained via simulation and they show that they are in line with each other, validating the accuracy of the testbed.
Highlights
An interconnected network that is used to deliver electricity from suppliers to consumers is what is called as “electrical grid”
This is due to the population growth and more modern electrical (a) appliances are being added in every household, such as high-definition televisions, laptops and wireless telephones
One of the advantages of Radio over Fiber (RoF) is that only minimal modifications are required at the base stations or access points since Radio Frequency (RF) signals are transmitted to remote antenna as it is
Summary
An interconnected network that is used to deliver electricity from suppliers to consumers is what is called as “electrical grid”. Challenges occur in ensuring the reliability and timeliness of the data transmitted over these networks Advance techniques such as cognitive radio [2] and fiber wirelesss (FiWi) are developed to fully utilize the capability of smart grid wireless networks. Cognitive radio networks allow unlicensed devices to transmit in unused “spectrum holes” in licensed bands without causing harmful interference to authorized users It configures the radio for different combinations of protocol, operating frequency, and waveform. It has higher probability to cause the signals to interfere with the licensed primary user This does not happen with FiWi as the optical side is able to provide reliable transmission for smart meter and intelligent sensor data, while the wireless side allows flexible access to remote locations and broad coverage. We introduce our proposed testbed and the final section concludes the paper
