Computer perspectives: the bandwidth famine
Communications of the ACM, 1990A number of years ago I visited a young and successful computer company and was given a tour of the facilities by one of the directors. We passed offices in which people were working at computer terminals; I was told they constituted the accounts department. A little further on we came to the software department; here people were also using terminals. “

Optical Computations for Image Bandwidth Compression. [PDF]
Abstract : This report summarizes the previous year's research in optical processing and optical/digital processing methods for image data compression. The following topics are discussed: (1) Radiometric and spatial transformations to achieve adaptive image data compression; (2) Spatial optical subsampling and spectral/spatial reconstruction for image ...

Increasing the human-computer bandwidth
Digest of Papers Compcon Spring '90. Thirty-Fifth IEEE Computer Society International Conference on Intellectual Leverage, 2002Topics discussed are high-definition television (HDTV), image compression, image density and dynamic range, and new application areas. HDTV will have a strong impact on the computing industry if it becomes a digital medium. It is certainly inevitable that HDTV will be digital, but it is as yet uncertain whether an intermediate analog standard will be ...

Joint Computation Offloading and Bandwidth Assignment in Cloud-Assisted Edge Computing
IEEE Transactions on Cloud Computing, 2022Offloading computation based on mobile edge computing paradigms can augment the computational capabilities of resource-scarce mobile devices. However, the capacity limitations of edge servers constrain the performance improvement achieved through computation offloading. In this paper, we consider a three-tier computation offloading schema with multiple

A bandwidth allocation scheme based on residual bandwidth information in mobile edge computing
Proceedings of the 2nd Workshop on Middleware for Edge Clouds & Cloudlets - MECC '17, 2017To meet the requirements of each flow in mobile edge computing (MEC) which coexists flows with different round-trip times (RTTs) and requirements about transmission rate, we previously proposed a bandwidth allocation scheme based on collectable information and showed the effectiveness of this approach in MEC.

Computing invariants in graphs of small bandwidth
Mathematics and Computers in Simulation, 1999Abstract Many graph invariants (chromatic number, rook polynomial, Tutte polynomial, etc.) are known to be computable for general graphs in exponential time only. Algorithms for their computation usually depend on special properties of the invariants and are not extendable to slightly different problems.

Increasing memory bandwidth for vector computations
1994Memory bandwidth is rapidly becoming the performance bottleneck in the application of high performance micro- processors to vector-like algorithms, including the "Grand Challenge" scientific problems. Caching is not the sole solution for these applications due to the poor temporal and spatial locality of their data accesses.

Improving Bandwidth Efficiency and fairness in cloud computing
2013 IEEE Global Communications Conference (GLOBECOM), 2013Bandwidth is a key resource in cloud networks. Every tenant wants to be assigned the bandwidth which is proportional to the price they have paid. At the cloud vender side, the link bandwidth utilization could be enhanced to support more clients.

Parallel Computation for the Bandwidth Minimization Problem
2009The bandwidth minimization problem is a classical combinatorial optimization problem that has been studied since around 1960. It is formulated as follows. Given a connected graph G = (V;E) with n nodes and m edges, find a labeling π, i.e. a bijection between V and {1; 2;… ; n}, such that the maximum difference |π(u)–(v)|, uv e E, is minimized.

An empirical study of bandwidth predictability in mobile computing
Proceedings of the third ACM international workshop on Wireless network testbeds, experimental evaluation and characterization, 2008While bandwidth predictability has been well studied in static environments, it remains largely unexplored in the context of mobile computing. To gain a deeper understanding of this important issue in the mobile environment, we conducted an eight-month measurement study consisting of 71 repeated trips along a 23Km route in Sydney under typical driving ...
