英文摘要	Rate adaptation (RA) has been traditionally used to achieve high goodput. In this work, we design RA for 802.11n NICs from an energy-efficiency perspective. We show that current MIMO RA algorithms are not energy efficient for NICs despite ensuring high throughput. The fundamental problem is that, the high-throughput setting is not equivalent to the energy-efficient one. Marginal throughput gain may be realized at high energy cost. We then propose EERA and EERA+, two energy-based RA schemes that trade off goodput for energy savings at NICs. EERA applies multidimensional ternary search and simultaneous pruning to speed up its runtime convergence in single-client operations, and uses fair airtime sharing to handle multiple-client operations. EERA+ further searches for multiple, staged rates to yield more energy savings over EERA. Our experiments have confirmed their effectiveness in various scenarios.; SCI(E); EI; ARTICLE; lichiyu@cs.ucla.edu; chunyi@cse.ohio-state.edu; chengpeng5555@csnet1.cs.tsinghua.edu.cn; slu@cs.ucla.edu; xwang8@sjtu.edu.cn; renfy@csnet1.cs.tsinghua.edu.cn; wangtao@pku.edu.cn; 6; 1333-1347; 15
