We apply hierarchical sparse coding, a form of deep learning, to model user-driven workloads based on on-chip hardware performance counters. We then predict periods of low instruction throughput, during which frequency and voltage can be scaled to reclaim power. Using a multi-layer coding structure, our method progressively codes counter values in terms of a few prominent features learned from data,...
In this paper, we propose a new throughput analysis for IEEE 802.11 distributed coordination function (DCF) considering the real channel conditions and capture effects under arbitrary load conditions employing basic access method. The aggregate throughput of a practical wireless local area (WLAN) strongly depends on the channel conditions. In real radio environment, the received signal power at the...
This paper presents an analytical model and the performance study of IEEE 802.11 distributed coordination function (DCF) for the nonsaturated heterogeneous traffic. In this paper, we modify the Bianchipsilas Markov chain model for the nonsaturated environment and analyze the throughput under several conditions and several set of parameters, with the aim of obtaining the accurate throughput when stations...
This paper presents an analytical model for the performance study of IEEE 802.11 distributed coordination function (DCF). The maximum throughput can be achieved well below the saturated load. The analytical model for finite load must be studied to know the performance of the medium access control (MAC) layer below the saturated load. We extend the Bianchipsilas saturation model for the nonsaturated...
