Lagrange's multiplier based resource management for energy efficient D2D communication in 5G networks

Device to device communication is the predominantly renowned trait for 5G network and IoT applications. In work, proposed novel joint low power/energy efficient resource allocation with mode selection D2D underlay in-band transmit power, interference, data rate constraints are investigated formulation of a problem which integrates three major modules (resource management, selection, power management) into one. To achieve we formulate optimization objective maximizing energy efficiency using subtractive form method solve fractional function an iterative algorithm. The formulated transformed min–max solved by Lagrange dual as lagrange multipliers via process optimal power. Numerical analysis exemplifies validates characteristics algorithm all ensure quality communication, 5G, applications industrial need devices promote conservation green communication.
