PROJECT TITLE :
Throughput–Delay Tradeoff in Interference-Free Wireless Networks With Guaranteed Energy Efficiency
Existing works have addressed the tradeoffs between any two of the 3 performance metrics: throughput, energy efficiency (EE), and delay. In this paper, we unveil the intertwined relations among these 3 metrics below a unifying framework and notably investigate the problem of EE-guaranteed throughput–delay tradeoff in interference-free wireless networks. We tend to initial propose 2 admission management schemes, known as the first-out and initial-in schemes. We have a tendency to then formulate it as two stochastic optimization issues, aiming at throughput maximization (in the first-out theme) or dropping rate minimization (in the primary-in scheme) subject to demand of EE (RoE), stability, admission management, and transmit power. To resolve the problems, the EE-Guaranteed algorithm for throUghput-delAy tRaDeoff (eGuard), respectively referred to as eGuard-I and eGuard-II in the first-out and first-in schemes, is devised. Moreover, with guaranteed RoE, we theoretically show that the eGuard (I and II) will not solely push the throughput arbitrarily close to the optimal with tradeoffs in delay but conjointly quantitatively control the throughput–delay performance on demand. Simulation results consolidate the theoretical analysis and significantly show the execs and cons of the 2 schemes.
