Media Flow Rate Allocation in Multipath Networks [PDF]
IEEE Transactions on Multimedia, 2007 We address the problem of joint path selection and source rate allocation in order to optimize the media specific quality of service in streaming of stored video sequences on multipath networks. An optimization problem is proposed in order to minimize the end-to-end distortion, which depends on video sequence dependent parameters, and network ...

Collaborative Rating Allocation [PDF]
Proceedings of the Twenty-Sixth International Joint Conference on Artificial Intelligence, 2017 This paper studies the collaborative rating allocation problem, in which each user has limited ratings on all items. These users are termed ``energy limited''. Different from existing methods which treat each rating independently, we investigate the geometric properties of a user's rating vector, and design a matrix completion method on the simplex. In

An approach to rate allocation in multicast [PDF]
42nd IEEE International Conference on Decision and Control (IEEE Cat. No.03CH37475), 2004 In multirate multicast different users in the same multicast group can receive services at different rates depending on their own requirements and the congestion level of the network. In this paper we present a general framework for addressing the optimal rate control problem in multirate multicast where the objective is the maximization of a social ...

Robust image transmission performed by SPIHT and turbo-codes [PDF]
Serbian Journal of Electrical Engineering, 2008 This work describes the method for providing robustness to errors from a binary symmetric channel for the SPIHT image compression. The source rate and channel rate are jointly optimized by a stream of fixed-size channel packets. Punctured turbo codes are

Power Allocation and User Grouping for NOMA Downlink Systems
Applied Sciences, 2023 Non-orthogonal multiple access (NOMA) technology allows multiple users to use the same time-frequency resource to send signals, which can improve spectral efficiency and throughput.

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 ...

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.

Discrete rate maximisation power allocation with enhanced BER [PDF]
, 2012 This study aims to maximise the rate over a multiple-in multiple-out (MIMO) link using incremental power and bit allocation. Two different schemes, greedy power allocation (GPA) and greedy bit allocation (GBA), are addressed and compared with the ...

A distributed algorithm for wireless resource allocation using coalitions and the Nash bargaining solution [PDF]
, 2011 In this paper a distributed, low-complexity, fast and fair resource allocation algorithm for a multiuser, wireless LTE OFDMA channel is proposed. Based on the game theoretic concept of the Nash Bargaining Solution and by grouping users into coalitions of
