Management of Quality of Service and other functions in mobile Ad Hoc networks
2003
Masteroppgave i informasjons- og kommunikasjonsteknologi 2003 - Høgskolen i Agder, Grimstad This Masters thesis deals with management of mobile Ad Hoc networks, with main focus on QoS management. The needs for management of such networks and the challenges in managing them are an important part of the theoretical discussion. Different methods like SNMP, ANMP, Guerrilla management and Policy-based management are described and evaluated in order to be used in management of mobile Ad Hoc networks. The task of managing a MANET is important in order to maintain an effective and stable network. Securing the transmission of data and avoiding unauthorized network users are important security tasks.…
Quality of service (QoS) in mobile ad hoc networks
2006
Masteroppgave i informasjons- og kommunikasjonsteknologi 2006 - Høgskolen i Agder, Grimstad Mobile ad hoc networks inherits several of the issues that ordinary wireless networks have and include several new ones. With internet becoming a multi media enviroment, there are many new requirements that must be satisfied, especially when it comes to real time service. Quality of servce protocol for MANETs has been a topic of interest. In this paper I propose a QoS –aware bandwidth protocol based on available bandwidth calculation. My proposal is based on a few existing proposals today and the theory around these. I then show an implementation available bandwidth calculation and routing functions.…
QoS for real-time IP traffic
2001
Masteroppgave i informasjons- og kommunikasjonsteknologi 2001 - Høgskolen i Agder, Grimstad This thesis focuses on three service models, known as Best Effort, IntServ and DiffServ, and their ability of providing QoS in IP networks. The objective is to evaluate the performance of real-time traffic based on theory and testing. In addition, mechanisms that may improve the QoS performance further, like MPLS and Bandwidth Brokers, are evaluated to find a comprehensive solution for different types of IP networks. Tests are set up to focus on typical behavior of the service models, and disclose differences in their efficiency together with problems concerning fairness in the bandwidth sharing. Res…
Migration of VOIP/SIP enterprise solutions towards IMS
2006
Masteroppgave i informasjons- og kommunikasjonsteknologi 2006 - Høgskolen i Agder, Grimstad Voice-over-IP solutions based on SIP and Skype are now widely spread and accepted by end-users. "Traditional Circuit Switched" voice services suffer from declining revenues, high maintenance cost, and a lack of integration with Internet applications. For an enterprise customer it is increasingly difficult to make a decision about which VoIP solution to select. For fixed and mobile operators new solutions based on IMS are on the horizon, and investment strategies for VOIP solutions are difficult. The research project will investigate VoIP/SIP solutions based on open source as a starting point, and out…
Research on the impact of using interactive game based learning to teach mathematics
2005
Masteroppgave i informasjons- og kommunikasjonsteknologi 2005 - Høgskolen i Agder, Grimstad The number of students who study scientific subjects has continued to drop over a long period of time. Compared to 2004, there is a 12% decrease in High School students who study mathematics and a 5% decrease in applicants for technology studies at College and University level in 2005 [1]. These numbers concern employees of the technology sector as they have predicted a large need for mathematicians in the future [19]. The educational system is under constant change to take advantage of new educational methods that modern technology allows for. The Heriot Watt University in Scotland showed that the i…
Data management and concurrency control in broadcast based asymmetric environments
2006
Masteroppgave i informasjons- og kommunikasjonsteknologi 2006 - Høgskolen i Agder, Grimstad Tens of millions of users have personal handheld devices with several network interfaces built-in, and the number of users and of network interfaces included are only increasing. This growth suggests a need for new methods to disseminate data to multiple clients, and cyclic broadcast is one approach. We do a survey on the various data management protocols that describe how to broadcast the data, and the concurrency control protocols that make sure all access to the database is consistent. The various data management and concurrency control techniques deals with the restrictions in asymmetric broadcas…
TsetlinGo : Solving the game of Go with Tsetlin Machine
2020
Master's thesis in Information- and communication technology (IKT590) The Tsetlin Machine have already shown great promise on pattern recognition and text categorization. The board game GO is a highly complex game, and the Tsetlin Machine have not yet been tested extensively on strategic games like this. This thesis introduces TsetlinGO and aims to Solve the game of Go with Tsetlin Machine. For predicting the next moves a combination of Tsetlin Machine and Tree Search was used. In the thesis a 9x9 board size was used for the game of Go, to prevent the problem from becoming to complex. This thesis goes through hyper-parameter testing for classification of the Go board game. A solution with T…
Playing endgame chess with the Tsetlin Machine
2020
Master's thesis in Information- and communication technology (IKT590) The report is about training an Artificial Intelligence(AI) that is able to play out endgames, using the existing solved endgame of chess to train the Tsetlin Machine on. This report describes the methods used to train and test a Tsetlin Ma-chine using both the convolutional and multiclass implementation. We have further tested out different methods to handle the data it trains on to investigate what methods work best. Where these methods are; to split the data for two machines for either white or black starting player, transforming the data to only be from one starting players perspective and one splitting based on resul…
Lost in Draft: Investigating Game Balance in Multiplayer Online Battle Arena Drafting
2021
Master´s thesis in Information and Communication Technology (IKT590) University of Agder, Grimstad This thesis explores modern machine learning solutions to turn-basedstrategy games. In particular, we explore the possibilities of equalizing the playing field for both teams in the draft phase of Defense of the Ancients 2 (Dota 2) and League of Legends (LoL), with both games being giants in the multi-million dollar esports industry. The thesis covers the Multiplayer Online Battle Arena video game genre and the draft phase the games use. We also discuss the tech-nology used to address the problem, as well as the basic concepts of modern machine learning that allowed this technology to arise. W…
Background noise classification and denoising of audio signals utilizing empirical wavelet transform and deep learning
2021
Master´s thesis in Information and Communication Technology (IKT590), University of Agder, Grimstad The importance of sound and speech cannot in human life cannot be overstated. Ambient sound informs us about our surroundings and warn us of potential dangers, such as a car approaching from behind. One of the most common modes of communication is speech. However, if it is contaminated with background noise, it may result in data loss. Recent advances in artificial intelligence enable machines to recognize and classify sound patterns, as well as remove complex background noise from contaminated speech. This thesis investigates a method for improving existing background noise classification an…
