Efficient Algorithms for Max-Weighted Point Sweep Coverage on Lines

open access: yesSensors, 2021
As an important application of wireless sensor networks (WSNs), deployment of mobile sensors to periodically monitor (sweep cover) a set of points of interest (PoIs) arises in various applications, such as environmental monitoring and data collection ...

Algorithmic approaches for network design with facility location: A survey [PDF]

open access: yesAUT Journal of Mathematics and Computing, 2022
We consider a family of problems that combine network design and facility location. Such problems arise in many practical applications in different fields such as telecommunications, transportation networks, logistic, and energy supply networks.

Algorithms For Positive Polynomial Approximation [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2019
Summary: We propose several algorithms for positive polynomial approximation. The main tool is a novel iterative method to compute nonnegative interpolation polynomials at any order, which is shown to converge under conditions that make it suitable for the numerical approximation of positive functions. Our method is based on the special representations

NORA: An Approach for Transforming Network Management Policies into Automated Planning Problems

open access: yesSensors, 2021
Realizing autonomic management control loops is pivotal for achieving self-driving networks. Some studies have recently evidence the feasibility of using Automated Planning (AP) to carry out these loops. However, in practice, the use of AP is complicated

A Primal–Dual-Based Power Control Approach for Capacitated Edge Servers

open access: yesSensors, 2022
The intensity of radio waves decays rapidly with increasing propagation distance, and an edge server’s antenna needs more power to form a larger signal coverage area.

An Improved Approximation Algorithm for the Minimum Power Cover Problem with Submodular Penalty

open access: yesComputation, 2022
In this paper, we consider the minimum power cover problem with submodular penalty (SPMPC). Given a set U of n users, a set S of m sensors and a penalty function π:2U→R+ on the plane, the relationship that adjusts the power p(s) of each sensor s and its ...

All-norm approximation algorithms [PDF]

open access: yesJournal of Algorithms, 2002
Summary: A major drawback in optimization problems and in particular in scheduling problems is that for every measure there may be a different optimal solution. In many cases the various measures are different \(\ell_p\) norms. We address this problem by introducing the concept of an all-norm \(\rho\)-approximation algorithm, which supplies one ...

On Strong Convergence of Halpern’s Method for Quasi-Nonexpansive Mappings in Hilbert Spaces

open access: yesMathematical Modelling and Analysis, 2016
In this paper, we introduce a Halpern’s type method to approximate common fixed points of a nonexpansive mapping T and a strongly quasi-nonexpansive mappings S, defined in a Hilbert space, such that I − S is demiclosed at 0.
