Packet Scheduling on the Wireless Channel
(2017-12-07)Scheduling has always been an indispensable part of resource allocation in wireless networks. Accurate information about channel-state is assumed as a modeling simplification. However, in a real-life network ,e.g., Long ... -
Passive localization of sound sources in shalow water simulation studies.
Array processing techniques for source localization in shallow waters can be classified as: i) Time delay estimation (TDE) techniques, and ii) High resolution (HR) methods. Time delay estimation techniques are two-step ... -
PC. base interferometer for radio astronomy
5.1 Review As shown in the previous chapters through analytical, design, and experimental studies, the PC?based DAS is a very useful building block in radio interferometry. This has enabled the development of a PC?based ... -
Perceptual Quality Assessment of Lowlight Restored and Authentically Distorted Images
The capability of hand-held devices to acquire high-definition visual content has led to a tremendous increase in the number of images and videos captured daily. However, camera hardware and pipelines are not perfect and ... -
Performance analysis and optimization of scheduling in high speed input queuing cell switches
It is well known that the phenomenon of Head-of-the-Line (HOL) blocking limits the maximum achievable throughput of a pure Input Queuing cell switch (in which there is only one queue at each input that buffers all the cells ... -
Performance Analysis Of A Variation Of The Distributed Queueing Access Protocol
(Indian Institute of Science, 2005-10-04)"A distributed queueing Medium Access Control (MAC) protocol is used in Distributed Queue Dual Bus (DQDB) networks. A modified version of the MAC protocol was proposed by R.R. Pillai and U. Mukherji in an attempt to overcome ... -
