Optimal Rate Allocation for Logowatermarking

2007 IEEE International Conference on Image Processing, 2007
Compression of logo as an image is addressed in logo watermarking, in which a framework of joint Human Vision System (HVS) model and rate allocation theory in the wavelet domain is applied. Under this framework, a novel logo watermarking algorithm using reversible discrete wavelet transform is proposed.

Bandwidth allocation, bit rate and pricing

IEEE International Conference on Communications, 2005. ICC 2005. 2005, 2005
In this paper we present a packet scheduling method which guarantees bandwidth of the connection and optimizes revenue of the network service provider. A closed form formula for updating the adaptive weights of a packet scheduler is derived from a revenue-based optimization problem.

The rate-allocation problem for turbo codes

IEEE Transactions on Communications, 2004
In this letter, we view the implicit unequal error protection observed in the asymptotic performance of most turbo codes as an impetus to the formulation of a rate-allocation problem, associated with the distribution of a fixed quota of coded bits in the trellis sections of the upper and lower recursive systematic convolutional codes of the turbo-code ...

Stability and Fairness of a Rate Allocation Scheme

Telecommunication Systems, 2002
In this paper, we analyze quantitatively the stability and equilibrium performance of a rate allocation scheme. This kind of analysis is important because in computer networks where multiple applications compete and share limited amount of system resources, some applications tend to suffer from variations in resource availability, and are desired to ...

A Competitive Rate Allocation Game

2012
We introduce a competitive rate allocation game in which two receivers compete to forward the data from a transmitter to a destination in exchange for a payment proportional to the amount of forwarded data. At each time slot the channel from the transmitter to each receiver is an independent random variable with two states, high or low, affecting the ...

Resource marking and fair rate allocation

2002 IEEE International Conference on Communications. Conference Proceedings. ICC 2002 (Cat. No.02CH37333), 2003
In resource marking theory, users adapt their rates according to their utility functions and congestion signals from the network. Using a special type of utility function, this leads to a proportionally fair rate allocation among the users. We examine the ability of two proposed resource marking implementations, random exponential marking (see ...
