A Distributed Minimum Spanning Tree Based on all Best Swap Edges in CRN
International Conference on Communication and Electronics Systems, 2019The minimum spanning tree is a fundamental problem in distributed networks. We wish to extend this problem into cognitive radio networks. In general, a tree spanner is minimum spanning tree T which has a real-weight with n vertex (or secondary user (SU))

The design of distributed approximation protocols is a relatively new and rapidly developing area of research. However, so far, little progress has been made in the study of the hardness of distributed approximation.

Uncertain Distribution-Minimum Spanning Tree Problem
International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2016This paper studies the minimum spanning tree problem on a graph with uncertain edge weights, which are formulated as uncertain variables. The concept of ideal uncertain minimum spanning tree (ideal UMST) is initiated by extending the definition of the uncertain [Formula: see text]-minimum spanning tree to reect the overall properties of the α-minimum ...

Energy-Optimal Distributed Algorithms for Minimum Spanning Trees
IEEE Journal on Selected Areas in Communications, 2008Traditionally, the performance of distributed algorithms has been measured in terms of time and message complexity.Message complexity concerns the number of messages transmitted over all the edges during the course of the algorithm. However, in energy-constrained ad hoc wireless networks (e.g., sensor networks), energy is a critical factor in measuring

A Fast Distributed Approximation Algorithm for Minimum Spanning Trees
Distributed Computing, 2006We give a distributed algorithm that constructs a O(logn)- approximate minimum spanning tree (MST) in arbitrary networks. Our algorithm runs in time $\tilde{O}(D(G) + L(G,w))$ where L(G,w) is a parameter called the local shortest path diameter and D(G) is the (unweighted) diameter of the graph.

Distributed Data Gathering Algorithm Based on Spanning Tree
IEEE Systems Journal, 2021The energy consumption of the nodes is limited in wireless sensor networks (WSNs). Since the sink node takes up most of the data forwarding, the energy consumption is maximum and it is easily formed around the energy hole.

Distributed Broadcast Minimum Spanning Tree (reliable version)
2007 3rd International Conference on Intelligent Sensors, Sensor Networks and Information, 2007DBMST is a broadcast communication protocol that provides a distributed MST algorithm It is based on the FPS power-management protocol. This paper presents the complete version of DBMST that regards packet loss and dynamism of the network topology and provides reliable communication.

Serial and parallel memetic algorithms for the bounded diameter minimum spanning tree problem
Expert Syst. J. Knowl. Eng., 2020Given a connected, weighted, undirected graph G = (V, E) and an integer D ≥ 2, the bounded diameter minimum spanning tree (BDMST) problem seeks a spanning tree of minimum cost, whose diameter is no greater than D.
