Energy-Efficient and QoS-Improved D2D Small Cell Deployment for Smart Grid

This paper proposes a device-to-device communication based small cell (SC) deployment scheme in Smart Grid, named as JODI-D2D, to achieve high QoS, high reliability, and high energy efficiency. SC deployment is formulated as a joint optimization of data rate maximization and interference minimization, serving the distributed smart grid user equipment (SGUE), while reducing the computation latency. The SC powering strategy is determined with the k-means clustering, which considers the features of SGUEs, endowed by both power and communication layers. Simulation results show that the proposed JODI-D2D achieves high QoS with improved data rate performance, sufficient computation latency and maximized energy efficiency for SG applications.
