Abstract :
In most designed adaptive modulation and coding (AMC) schemes the data link layer transmission rate is adapted only against physical layer channel variation. The highly fluctuating queuing process at the data link layer is not fully investigated. In this study, we first research on more advanced AMC mode selection algorithms and then propose a two-dimensional cross- layer optimization scheme. This scheme applies both policy domain optimization and channel domain improvement to achieve the best solution. With the same transmission power, the proposed two-dimensional optimization scheme is shown to be capable of offering lower minimum end-to-end packet loss probability than the existing one-dimensional optimization design.
