On utility‐optimised router‐level bandwidth allocation

Transactions on Emerging Telecommunications Technologies, 2012
ABSTRACTKelly's network utility maximisation (NUM) problems and solutions are aimed to maximise the aggregate utility subject to link capacity constraints. They are formulated and solved by using the individual flow rate vector. Because of the architecture of the current networks such as the Internet, the individual flow rates are generally not ...

Performance Analysis of Bandwidth Utilization in WiMAX Network

2015 International Conference on Computing Communication Control and Automation, 2015
Worldwide Interoperability for Microwave Access (WiMAX) is currently one of the newest technologies in wireless communication. International Telecommunication Union (ITU) has defined a spectrum for each region, (Asia is in 3rd region) which is fixed for lifetime.

Large Bandwidth Optical Modulators Utilizing Millimeter Wavelength Drivers

MTT-S International Microwave Symposium Digest, 2005
This paper describes the research and development effort under way at Hughes Research Laboratories (HRL) to design, fabricate, and test infrared traveling-wave modulators that can be excited by millimeter-wavelength drivers. The modulators are designed for eventual use in high-data-rate communication systems and for laser wave-length shifting in ...

Maximum spectrum utilization by wide bandwidth transmission

IEEE Transactions on Vehicular Communications, 1963
Because more and more people communicate with one another, various frequency bandwidths have become congested. In the future there will be growing need for more efficient utilization of bandwidth. To reduce this congestion the tendency has been to use smaller transmission bandwidths.

Bandwidth utilization efficiency enhancement for OFDM‐based WSN

International Journal of Communication Systems, 2018
SummaryNormally IEEE 802.16 (WiMAX) is used for mainly downlink traffic applications. However in the upper tier of 2‐tier (WiMAX‐WiFi) wireless sensor network, the uplink bandwidth faces bottlenecks for high throughput. In this paper, a solution has been proposed for this limitation of uplink bandwidth allocation through the use of queuing theoretic ...

Utility-Based Bandwidth Allocation for Triple-Play Services

Fourth European Conference on Universal Multiservice Networks (ECUMN'07), 2007
It is expected that, in near future, the multi-class traffic previously in public switched telephone network (PSTN), cable television network and IP network will be multiplexed at backbone and carried by the converged next-generation network (NGN). A pragmatic challenge in facilitating NGN is how to schedule traffic and allocate bandwidth among the ...

New coding techniques for improved bandwidth utilization

Proceedings of 37th Conference on Foundations of Computer Science, 2002
The introduction of parallel models that account for communication between processors has shown that interprocessor bandwidth is often the limiting factor in parallel computing. In this paper, we introduce a new coding technique for transmitting the XOR of carefully selected patterns of bits to be communicated which greatly reduces bandwidth ...

Utilizing Sensor Arrays to Attain High-Operating Bandwidth

Journal of Dynamic Systems, Measurement, and Control, 2004
Proposed in this paper is a methodology for the design of a sensor array of small bandwidth passband sensors (sensors with small bandwidth but different bandwidths) to attain a high operating bandwidth. In certain control applications, it is necessary that a high bandwidth sensor be used for feedback efficiency.

Utilizing memory bandwidth in DSP embedded processors

Proceedings of the 38th conference on Design automation - DAC '01, 2001
This paper presents a network flow approach to solving the register binding and allocation problem for multi word memory access DSP processors. In recently announced DSP processors, such as Star*core, sixteen bit instructions which simultaneously access four words from memory are supported. A polynomial-time network flow methodology is used to allocate

EFFICIENT BANDWIDTH UTILIZATION FOR DOWNLOADING WEB PAGES

International Journal of Computers and Applications, 2014
AbstractWeb crawler is a computer program that browses World Wide Web in methodical and automated manner. Latest crawling techniques in use are parallel crawling and hierarchical crawling. In later case, total Web site is extracted by dividing it into a few levels. The homepage from which crawling process starts is considered to be the first level. All
