Optimizing D2D transmission for secure and reliable smart grid communication

Smart grid (SG) has been recognized as a promising solution to manage and distribute electricity in the next generation power systems. The large number of devices in power systems make the wired communication a non feasible solution, thus wireless transmission becomes necessary. However this demands a huge portion of radio spectrum. In this work, we aim to provide the secure and reliable SG communication through an efficient spectrum sharing mechanism. Specifically, we consider an underlay transmission and seek to minimize the interference under complete spectrum reuse while guaranteeing the required secrecy rate as well as end to end delay. A mathematical optimization problem is formulated and convex optimization techniques are exploited to find the near optimal solution. Further a suboptimal solution is also proposed to reduce the computational complexity. Simulation results are presented to verify the effectiveness of the proposed schemes.
