Software-Defined Networking not only addresses the shortcoming of traditional network technologies in dealing with frequent and immediate changes in cloud data centers but also made network resource management open and innovation-friendly. To further accelerate the innovation pace, accessible and easy-to-learn testbeds are required which estimate and measure the performance of network and host capacity...
Analytical modeling plays a unique and important role in computer architecture design, providing a first-order estimate, reducing the design search space size for simulation, or giving insights on basic relationships between various variables and parameters. However, current practices in using analytical models face considerable hurdles: models vary widely in types, predictive capability, and assumptions...
In the imaging algorithms of Inverse Synthetic Aperture Sonar (ISAS), Range-Doppler Algorithm (RDA) and Polar Formation Algorithm (PFA) can be only suitable for far-field imaging. For obtaining near-field imaging, Computed Tomography Algorithm (CTA) is introduced. Five point-targets in near-field at different locations are imaged with RDA, PFA and CTA, respectively. Imaging results show that five...
In this paper we present an algorithm, based on power management of access points (AP), to reduce congestion in wireless local area networks (WLANs). The algorithm finds the most congested access point (MCAP) and adjusts its transmitted power in discrete steps and determines the optimal userspsila assignment such that an optimal load distribution is achieved. Results show that the algorithm is capable...
