Abstract :
Link adaptation mechanisms are viewed as one of the key techniques for increasing the diversity order, robustness and effectiveness of a wireless communication system. Traditional schemes are designed to increase the system capacity and momentary transmission spectral efficiency. In this paper we present a novel algorithm in which we co-design Adaptive Modulation and Coding (AMC), Hybrid ARQ (HARQ) and power control in order to enhance the energy efficient of packet delivery. Our goal is to reduce the overall transmission energy consumption while meeting the QoS constraints of heterogeneous application services. Our analysis reveals how the proposed approach permits to achieve notable energy gain over traditional adaptive mechanism design.
