Distributed Rate Allocation for Inelastic Flows [PDF]
IEEE/ACM Transactions on Networking, 2007 A common assumption behind most of the recent research on network rate allocation is that traffic flows are elastic, which means that their utility functions are concave and continuous and that there is no hard limit on the rate allocated to each flow. These critical assumptions lead to the tractability of the analytic models for rate allocation based ...

High Performance Short Polar Codes: A Concatenation Scheme Using Spinal Codes as the Outer Code
IEEE Access, 2018 An innovative scheme for concatenating the polar codes with the recently proposed spinal codes is presented in this paper. The primary objective is to improve the performance of the polar codes in the finite-length regime.

Lossy network correlated data gathering with high-resolution coding [PDF]
, 2005 Sensor networks measuring correlated data are considered, where the task is to gather data from the network nodes to a sink. A specific scenario is addressed, where data at nodes are lossy coded with high-resolution, and the information measured by the ...

Rate Allocation and Content Placement in Cache Networks [PDF]
IEEE INFOCOM 2021 - IEEE Conference on Computer Communications, 2021 We introduce the problem of optimal congestion control in cache networks, whereby \emph{both} rate allocations and content placements are optimized \emph{jointly}. We formulate this as a maximization problem with non-convex constraints, and propose solving this problem via (a) a Lagrangian barrier algorithm and (b) a convex relaxation.

Cross-Layer Optimal Rate Allocation for Heterogeneous Wireless Multicast
EURASIP Journal on Wireless Communications and Networking, 2009 Heterogeneous multicast is an efficient communication scheme especially for multimedia applications running over multihop networks. The term heterogeneous refers to the phenomenon when multicast receivers in the same session require service at different ...

Achievable Rate and Optimal Physical Layer Rate Allocation in Interference-Free Wireless Networks [PDF]
, 2009 We analyze the achievable rate in interference-free wireless networks with physical layer fading channels and orthogonal multiple access. As a starting point, the point-to-point channel is considered.

Resource Allocation for Multicarrier Rate-Splitting Multiple Access System
IEEE Access, 2020 In this article, we investigate the resource allocation problem for the multicarrier rate-splitting multiple access (RSMA) systems. On each subcarrier, messages are non-orthogonal superimposed on the power domain through the one-layer RSMA scheme.

Resource allocation, hyperphagia and compensatory growth [PDF]
, 2004 Organisms often shown enhanced growth during recovery from starvation, and can even overtake continuously fed conspecifics (overcompensation). In an earlier paper (Ecology 84, 2777-2787), we studied the relative role played by hyperphagia and resource ...

Distributed Storage Allocations for Optimal Service Rates [PDF]
IEEE Transactions on Communications, 2021 Redundant storage maintains the performance of distributed systems under various forms of uncertainty. This paper considers the uncertainty in node access and download service. We consider two access models under two download service models. In one access model, a user can access each node with a fixed probability, and in the other, a user can access a
