Optimal rate allocation and scheduling in cooperative streaming

39th Annual IEEE Conference on Local Computer Networks, 2014
While the demand for multimedia streaming, especially from mobile devices, is growing rapidly, mobile devices are challenged by the variable transmission rate in wireless channels and limited battery capacity. In this paper, we propose an energy-efficient cooperative streaming system. In the proposed system, mobile devices collectively stream a copy of

Convergence Rates for the Optimal Values of Allocation Processes

Mathematics of Operations Research, 1984
The optimal allocation process is of the following type. A sequence of functions (production functions) f1, f2, …, is given, each mapping R+n into [0, ∞). Along with it a vector q > 0 in R+n (vector of resources) is provided. For each integer k we consider the problem [Formula: see text] Here R+n is the nonnegative orthant of the n-dimensional ...

Rate allocation for Multihop routing in anonymous networking

2014 48th Annual Conference on Information Sciences and Systems (CISS), 2014
This work investigates Multi-hop routing for single destination mix networks; mixes are routers or proxy servers that use layered encryption, delaying, and packet reordering to provide source anonymity to packets that arrive at a common destination. In this work, the optimal rate allocation across multiple paths that maximizes anonymity under fixed ...

Estimation of Allocation Rates in a Cluster Analysis Context

Journal of the American Statistical Association, 1985
A sample of multivariate observations is assumed to be drawn from a mixture of a given number of underlying populations. The mixture likelihood approach to clustering is used to allocate each individual in the sample to its population of origin on the basis of the estimated posterior probabilities of population membership.

Rate Allocation for Cooperative Transmission in Parallel Channels

IEEE GLOBECOM 2007-2007 IEEE Global Telecommunications Conference, 2007
In this paper, we consider cooperative transmission between two source and destination pairs. Exchange of data is allowed between the two source nodes. In addition to the direct transmission link from the source to the intended destination, we have a two-hop relay link that sends the data via the neighboring source node. We partition the bandwidth into

Global Rate Allocation and Control

1994
The Galileo mission to Jupiter is now faced with extreme limitations in its communication downlink capability as a result of the inability of ground controllers to open its main antenna. Consequently, the rate that the Galileo spacecraft will be able to acquire data will exceed its capability to transmit it back by several orders of magnitude.

Rate Allocation in a Two Quantizer Coding System

2014 Data Compression Conference, 2014
The issue of backwards compatible image and video coding gained some attention in both MPEG and JPEG, let it be as extension for HEVC, let it be as the JPEG XT standardization initiative of the SC29WG1 committee. The coding systems work all on the principle of a base layer, perating in the low-dynamic range regime, using a one-mapped version of the HDR

An Allocation Rule with Wealth‐Regressive Tax Rates

Journal of Public Economic Theory, 2002
We introduce a public good allocation rule whose direct implementation by asking agents their endowments leads to Nash equilibrium outcomes—always Pareto dominating voluntary contributions outcomes. Although the Nash equilibrium allocations induced by this rule are not Pareto optimal in general, they are so in two‐person economies.

Deadzone Based Rate Allocation for JPEG XR

2011 Data Compression Conference, 2011
Similar to the JPEG image compression standard, the JPEG XR image compression solely controls the image quality loss and hence the output rate by means of the quantizer bucket sizes, a precise rate control mechanism like the EBCOT rate allocation algorithm in JPEG 2000 is not specified, and hence rate-distortion optimality of the quantizer is, in ...

Time allocation and response rate.

Journal of the experimental analysis of behavior, 2010
Food reinforcement for key pecking by three pigeons was arranged by a variable-interval schedule and a device that assigned each reinforcement to one of 10 component response rates corresponding to 10 classes of equally reinforced interresponse times ranging from 1.0 to 6.0 sec in 0.5-sec classes.
