Future green technologies require the reduction of power consumptions, increasing energy efficiencies, and managing the electromagnetic interference footprints. In this paper, we investigate the use of randomized transmit power strategy in which the nodes transmit with random power in a single-hop ad hoc wireless network. We assume Nakagami-m channel with very slow feedback channel for power update commands. Hence, by using the characteristic function of the received power, we develop a new mathematical formulation for the outage probability. Further, we test the developed formulation on the known constant transmit power case and randomized uniform distribution with constant maximum case. We show that the performance in terms of outage probabilities and total power consumption of all nodes is generally poor. Therefore, we extend our results to the case of optimized constant power and propose the use of randomized uniform distribution with optimized maximum power. We show that the proposed power distribution outperforms the previous ones and reduces the overall power consumption by many orders of magnitude.
