Abstract :
This paper addresses the issue of energy efficiency for error control mechanisms over wireless personal area networks. The study of the trade-off between link layer performance and energy consumption for error control schemes based on ARQ leads to the definition of an optimum value of the SNR to be used by the inner loop power control in MC-SS-based air interface. In the classical implementation of the power control, the value of the SNR depends on performance metrics such as BER/FER. The proposed implementation is an example of explicit physical/link layer cross-layer optimization with top-down approach
