1. 1. Dynamic Bandwidth Allocation for Wireless Nodes with Software Defined Networking in Heterogeneous Networks with Embedded Systems

   University essay from Mälardalens högskola/Akademin för innovation, design och teknik

   Author : Thomas Jädal; Dirk Postol Dissel; [2019]
   Keywords : ;

   Abstract : In the wireless computer networks of today, there is a limitation on how wireless access points handle bandwidth distribution to wireless nodes, both in Software Defined Networking (SDN) solutions, traditional networks with routers and switches, and in embedded systems. The limitation is the lack of control of the node bandwidth usage. READ MORE

3. 2. Analysis and Comparison of Distributed Training Techniques for Deep Neural Networks in a Dynamic Environment

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Ermias Gebremeskel; [2018]
   Keywords : deep learning; large scale distributed deep learning; data parallelism;

   Abstract : Deep learning models' prediction accuracy tends to improve with the size of the model. The implications being that the amount of computational power needed to train models is continuously increasing. Distributed deep learning training tries to address this issue by spreading the computational load onto several devices. READ MORE

4. 3. Design and Performance Evaluation of Resource Allocation Mechanisms in Optical Data Center Networks

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Nikam Vikrant; [2016]
   Keywords : Data Center Networks; Optical Circuit Switching; Routing and Wavelength Assignment; Network Function Virtualization; Virtual Network Function Service Chaining; Datacenternätverk; Optisk kretskoppling; Routing och våglängd uppdrag; Nätverksfunktionen virtualisering; VNF-tjanstekedjning VNF-tjänstekedjor;

   Abstract : A datacenter hosts hundreds of thousands of servers and a huge amount of bandwidth is required to accommodate communication between thousands of servers. Several packet switched based datacenter architectures are proposed to cater the high bandwidth requirement using multilayer network topologies, however at the cost of increased network complexity and high power consumption.

5. 4. A distributed, load-aware, power and frequency bargaining protocol for LTE-based networks

   University essay from Kommunikations- och transportsystem; Tekniska högskolan

   Author : Muhammad Sajid; Imran Siddiqui; [2012]
   Keywords : LTE; OFDMA; FFR; protocol; power allocation; frequency allocation.;

   Abstract : In this thesis a distributed, dynamic, load aware, joint power and frequency allocation protocol for 4G networks along with system-level simulated results are presented. In all cellular networks, a key limiting factor for throughput is inter-cell interference, especially at the cell edges. READ MORE

6. 5. A Joint Subcarrier/Power allocation Scheme for OFDMA-based Cellular Networks

   University essay from Kommunikations- och transportsystem; Tekniska högskolan

   Author : Aamir Abdul Aziz Hasan Ali; Muhammad Adil Shahzad; [2012]
   Keywords : ;

   Abstract : The assignment of this master thesis consists of initiating power, subcarrier allocation in a dynamic FFR based scheme designed for multi-cell OFDMA networks and to enhance the throughput of all center users in bandwidth hungry borrower cells (overloaded cells) which was previously degraded by original FFR3 scheme as a result of partitioning of system bandwidth into center and edge bands respectively. The method uses band borrowing to compensate center user’s throughput loss in a semi and fully overloaded system. READ MORE
