Complex adaptive system simulation of cellular network subscriber behaviour

Nel, Trevor Jon 29 June 2015 (has links)
M.Sc. (Information Technology) / Making changes to a complex system, such as a cellular network, without being well informed about the potential effects of the change could prove to have negative and costly outcomes. In order to diminish the risk of making changes to a real system, a simulation of the real system is a viable and valuable alternative. By creating a simulation of the real system, the effects of changes made can be tested in the simulation instead of the real system. The dissertation presents a model by which subscriber behaviour within a cellular network can be simulated. The model that is introduced to this end is called the Mobile Network Subscriber-Behaviour Simulation (MNSS). Subscriber behaviour is important as it is largely responsible for the variation in traffic within the cellular network. Thus, the research presented in the dissertation seeks to provide a means by which the planning and operation of cellular networks can be enhanced through a better comprehension of network traffic, which is influenced by subscriber behaviour. In the dissertation, specific focus is given to voice traffic, and, as such, the cellular network architecture that was chosen for the model is the GSM mobile network architecture due to its ubiquitous use in carrying voice traffic. The research presented in the dissertation begins with a discussion on the GSM architecture. Subscriber behaviour is simulated through the use of intelligent agents that are configured to interact with one another to form a Multi-agent System. In addition, the subscriber agents interact with, and adapt to, the mobile network component of the MNSS model, which constitutes the formation of a Complex Adaptive System. Therefore, the discussion is subsequently directed towards Artificial Intelligence, intelligent agents, Multi-agent Systems and Complex Adaptive Systems. Using these aforementioned concepts, the dissertation presents the MNSS model and a prototype implementation, as well as a discussion on the results obtained from this. The main purpose of the dissertation is to examine a means by which subscriber behaviour can be simulated in a cellular network, through the use of multiple intelligent agents that interact in a complex system. This is conducted for the express purpose of analysing the change in behaviour of the subscriber agents in relation to changes made to external conditions, such as the underlying cellular network or the behaviour of other subscriber agents.

On-the-go text entry: evaluating and improving mobile text input on mini-qwerty keyboards

Clawson, James 13 November 2012 (has links)
To date, hundreds of millions of mini-QWERTY keyboard equipped devices (miniaturized versions of a full desktop keyboard) have been sold. Accordingly, a large percentage of text messages originate from fixed-key, mini-QWERTY keyboard enabled mobile phones. Over a series of three longitudinal studies I quantify how quickly and accurately individuals can input text on mini-QWERTY keyboards. I evaluate performance in ideal laboratory conditions as well as in a variety of mobile contexts. My first study establishes baseline performance measures; my second study investigates the impact of limited visibility on text input performance; and my third study investigates the impact of mobility (sitting, standing, and walking) on text input performance. After approximately five hours of practice, participants achieved expertise typing almost 60 words per minute at almost 95% accuracy. Upon completion of these studies, I examine the types of errors that people make when typing on mini-QWERTY keyboards. Having discovered a common pattern in errors, I develop and refine an algorithm to automatically detect and correct errors in mini-QWERTY keyboard enabled text input. I both validate the algorithm through the analysis of pre-recorded typing data and then empirically evaluate the impacts of automatic error correction on live mini-QWERTY keyboard text input. Validating the algorithm over various datasets, I demonstrate the potential to correct approximately 25% of the total errors and correct up to 3% of the total keystrokes. Evaluating automatic error detection and correction on live typing results in successfully correcting 61% of the targeted errors committed by participants while increasing typing rates by almost two words per minute without introducing noticeable distraction.

Audience participation using mobile phones as musical instruments

Lee, Sang Won 21 May 2012 (has links)
This research aims at a music piece for audience participation using mobile phones as musical instruments in a music concert setting. Inspired by the ubiquity of smart phones, I attempted to accomplish audience engagement in a music performance by crafting an accessible musical instrument with which audience can be a part of the performance. The research begins by reviewing the related works in two areas, mobile music and audience participation at music performances, builds a charted map of the areas and its intersection to seek an innovation, and defines requisites for a successful audience participation where audience can participate in music making as musicians with their mobile phones. To make accessible audience participation, the concept of a networked multi-user instrument is applied for the system. With the lessons learnt, I developed echobo, a mobile musical instrument application for iOS devices (iPhone, iPad and iPod Touch). With this system, audience can download the app at the concert, play the instrument instantly, interact with other audience members, and contribute to the music by sound generated from their mobile phones. A music piece for echobo and a clarinet was presented in a series of performances and the application was found to work reliably and accomplish audience engagement. The post-survey results indicate that the system was accessible, and helped the audience to connect to the music and other musicians.

An investigation into the challenges faced by a mobile service provider in meeting customer needs

Govender, Omashan Vaughn January 2017 (has links)
Submitted in fulfillment of the requirements for the degree of Masters of Technology: Business Administration, Durban University of Technology, Durban, South Africa, 2017. / The term “wireless network” pertains to a very comprehensive field and at different points in history, meant different things. For example, in 1901 it would have meant Marconi’s first transatlantic communication and later, to the walkie-talkie in the Second World War. Since the late 1940’s, large companies and emergency services have used wide area private networks which could also be catergorised as wireless networks. However, public consciousness of wireless networks only arose in the 1980’s through the commercial distribution of cellular mobile radio. The telecommunications industry is experiencing a phenomenal revolution in which; the driving factors are innovative technologies, deregulation and globalization. Innovative technologies introduce dynamic changes in the way that telecommunication business is conducted. Deregulation is the liberalization of telecommunications which significantly increases the telecommunications market, while also allowing for strong competition amongst mobile service providers. Globalisation is the breakdown of legacy barriers which forces monopolistic service providers to compete in the international arena. With service delivery being identified as one of the key components for a successful telecommunications service provider, along with the Quality of Service of their network, both components are evaluated to determine how efficient the organisation is within the mobile telecommunications industry. Telecommunications service delivery is a way of ensuring the Quality of Service delivered for outsourced and retained services. The responsibilities of the mobile operator include monitoring, analyzing and reporting on service delivery performance in order, to ensure that customer satisfaction is met or even exceeded by the mobile operator. The South African mobile telecommunication industry is experiencing phenomenal growth, just like the rest of the world. Over the last two decades, the South African mobile telecommunications industry has experienced dramatic changes. Fixed line service providers have expanded into the mobile arena. Mobile operators are trying to form mergers and purchase fixed line companies. This study investigates the challenges faced by a mobile service provider in meeting internal customer needs. The Quality of Service (QoS) of the mobile network was evaluated and the various elements which contribute to challenges experienced by the service provider were identified. A mixed methods data collection method was employed for this study. To obtain the qualitative data, semi-structured interviews were conducted with management staff. Quantitative data was obtained through the use of questionnaires and an existing discourse analysis was conducted to identify characteristics on existing reports which were generated from within the organisation, for data collection. The results showed that the mobile operators had to be innovative and competitive simultaneously. Mobile operators face various challenges. The increased level of competition amongst service providers ensured improved QoS and service delivery to consumers. The mobile operator’s network foot print has to increase to provide its own network availability to clients. In order to avoid or reduce network sharing or roaming of network services as this comprises the client network coverage on the network. The mobile service provider should actively analyse network traffic to avoid potential disruptions and, to ensure that customers have a seamless connection. This study concludes that the changing environment of communications forces organizations to consistently re-evaluate their strategies and necessary re-align their strategies to the business needs of the organisation. The initial planning entails making technology choices to meet the overall business goals. However, technology is changing at an exponential rapid rate; therefore the organization should reach the completion of the product life cycle to ensure that this product is still required in the market. The main finding of this study reinforced the contention that planning is the most critical part of mobile network strategy. The organisation’s strategy may change to accommodate environmental changes. However, these changes should not affect the life cycle of the blueprint design. / M

An opportunity exploration and best practices analysis for South African mobile value-added companies entering the Ghanaian market

Hatting, Henry Lindo 04 1900 (has links)
Thesis (MBA)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: Mobile penetration in Ghana and the rest of Western Africa is reaching maturity. Mobile operators are looking for ways to complement their traditional revenue streams, as they cannot merely rely on voice and short message service (SMS) income anymore. Mobile value-added services are a good addition to the portfolio, bringing much needed services like transactional banking, commerce, information and entertainment, insurance, and health information services to mobile users that had difficult to no access to the above services until recently. South African mobile value-added services (VAS) companies that have a good relationship with market leading mobile providers, like MTN, have the opportunity to tap into the Ghanaian market as these services predominantly consist of mobile financial services products with limited functionality. Other specific services like agriculture, health, entertainment and insurance have been identified as mobile subscriber needs in the Ghanaian market. The benefit that South African mobile value-added companies have is that they already have developed similar well-functioning value-added services for the local market where comparisons with the Ghanaian market dynamics can be found. These companies can tailor them to the specific needs and requirements of the market in Ghana, saving them time and having the much-needed first mover advantage with regards to new or better mobile VAS in this market. Ghana is seen as the most stable country in the West African region and ease of doing business is good in comparison with neighbouring countries like Nigeria. Ghana is therefore a good entry point for South African mobile VAS companies in the West African market to truly scale their business model. The researcher chose to investigate the opportunities and best ways to enter this market by interviewing a project manager and managing director of a leading mobile value-added services company doing business in emerging economies, including Ghana. Questionnaires were also sent to employees working for various mobile VAS employers with extensive experience in the research and development of mobile VAS in these markets. The researcher derived information on the difficulty of doing business in Ghana; the current available VAS in the Ghanaian market; factors that hinder business growth in this market specifically; drivers of success; the importance of partnering with leading mobile operators like MTN to be successful; how the South African business model can be compatible; South African and other African trends that will most likely overflow to Ghana; together with the size data-enabled VAS which will form part of the portfolio of products that mobile VAS companies can offer and be market ready for in the near future. The findings of the researcher can be used as a starting framework to further investigate and determine specific market size and to conduct in-depth market analysis of the needs and requirements of mobile subscribers with regards to mobile VAS in Ghana with the vision of moving into the rest of Western Africa.
