Abstract

A packet-based power scheme is proposed in this paper. The proposed power control scheme aims at minimizing the total number of transmission that a packet needs before it is receive successfully over a Rayleigh fading channel subjected to two constraints. One is that the transmission power should be greater than zero. The other imposed by the constraint on the total transmission power at the base station. We use the augmented Lagrangian multiplier method to solve this problem and provide a theoretical solution. The simulation results show that, with the proposed power control scheme, the number of re-transmission can be reduced and the delay of a packet waste in the channel can be decreased as well.
