Optimal Rate Allocation in Cluster-Tree WSNs [PDF]
Sensors, 2011 In this paper, we propose a solution to the problem of guaranteed time slot allocation in cluster-tree WSNs. Our design uses the so-called Network Utility Maximization (NUM) approach as far as we aim to provide a fair distribution of the available ...

Generalized Geometric Programming for Rate Allocation in Consensus [PDF]
2017 55th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2017 Distributed averaging, or distributed average consensus, is a common method for computing the sample mean of the data dispersed among the nodes of a network in a decentralized manner.

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.

‘Codes are not enough…’: a report of ongoing research [PDF]
, 2008 We consider the problem of rate allocation in a fading Gaussian multiple-access channel (MAC) with fixed transmission powers. Our goal is to maximize a general concave utility function of transmission rates over the throughput capacity region.
