Branch-Based Centralized Data Collection for Smart Grids Using Wireless Sensor Networks

Abstract: A smart grid is one of the most important applications in smart cities. In a smart grid, a smart meter acts as a sensor node in a sensor network, and a central device collects power usage from every smart meter. This paper focuses on a centralized data collection problem of how to collect every power usage from every meter without collisions in an environment in which the time synchronization among smart meters is not guaranteed. To solve the problem, we divide a tree that a sensor network constructs into seve… Show more

“…With the advancement of wireless networks, wireless sensor networks have gradually become a key technology to collect and process power trading information. Kim et al [29] designed a branch-based wireless sensor network, which can efficiently collect the power consumption data of each user in a centralized power trading without conflicts due to the time synchronization of smart meters. The electricity market with centralized power trading is common, but the centralized structure will bring centralization issues, such as single points of failure.…”
