Abstract

An augmented model to greedy multi-rate power control schemes is proposed that integrates mobility information to increase the optimization margins of power efficient packet transmission. The proposed model can be considered as a hierarchical multi-rate power control scheme, where current rate allocation decisions are influenced by a larger time horizon that contains information about directionality and velocity of vehicular mobile users. In this paper we integrate the mobility aware algorithm with a greedy channel rate allocation scheme to illustrate its effectiveness. Numerical investigations show that required power per transmitted packet can be reduced on average by 40% without penalizing throughput.
