Energy-Aware Outage Probability Minimization in DF-Relayed Power Line Communication

Here, we investigate a novel constrained optimization problem that minimizes an energy-efficiency based outage probability by jointly optimizing the relay location and transmit power over the cooperative power line communication (PLC). It has been shown that the problem is generalized convex and has a global solution. Further, in order to reduce the computational complexity as well as to obtain design insights on the optimization, a nontrivial low-complexity tight approximation has been discoursed that gives closed-form of the optimal solution. Lastly, we observe that the proposed joint optimization scheme can yield a significant gain of around 57% against a benchmark.
