To reduce the idle access, an algorithm featured by low channel access delay and priority differentiation service was proposed for the access procedure of IEEE 802.11. A state-dependent two-level polling model was established to analyze the QoS performance of M2M under unsaturated condition and perfect channel in the IEEE 802.11. To improve the transmission effective of massive M2M service, machine...
Backfilling is well known in parallel job scheduling to increase system utilization and user satisfaction over traditional non-backfilling scheduling algorithms, which allow small jobs from the back of the queue to execute before larger jobs arriving earlier, and resources could be reserved to protect the latter from starvation. This paper proposed a relaxed backfill scheduling mechanism supporting...
The Real Time Kinematics Global Positioning System (RTK-GPS) has been proved to be a feasible tool for structure health monitoring. However, there are some limitations using the traditional RTK method under the long baseline conditions, and annoying ionospheric delay.To eliminate this delay, in this paper we present an improved Extended Kalman Filter with Triple-Differenced Ionospheric-Free (EKF-TDIF)...
Scalability considerations drive the evolution of switch design from output queueing to input queueing and further to combined input and crosspoint queueing (CICQ). However, CICQ switches with credit-based flow control face new challenges of scalability and predictability. In this paper, we propose a novel approach of rate-based smoothed switching, and design a CICQ switch called the smoothed buffered...
