The Global System for Mobile Communications (GSM) allows user universal and worlwide access to information and the ability to communicate with each other independently of their location and mobility. Tracking mobile users is one of the basic functions of the network system and one of the important issues in the design of a mobile computing system is how to manage the real-time locations of mobile clients. Most of the mobile computing applications are expected to support location- dependent continuous queries (LDCQs) in the near future and the result of a LDCQ depends on the current locations of the moving objects on which the query has been issued as well as the location of the mobile client, which issues the query. When the query is specified as continuous, the requesting client can get continuously changing result. In order to provide correct and timely results to requesting clients, the locations of moving objects as well as the locations of the requesting clients have to be closely monitored. The conventional database technology is not sufficient for processing of location-dependent continuous queries (LDCQs). In order to process LDCQs efficiently, a distance-based Adaptive Monitoring Method (AMM) was proposed in [LULCL01]. The aim of AMM is to maintain the correctness of the results of query evaluation without significantly increasing the wireless bandwidth requirements. In this thesis, we study how to generate location update with the distance-based update method in a GSM network. Extensive simulation experiments have been conducted to investigate the performance of AMM method in a GSM network.

Location Prediction of Mobile Phone Users Using Apriori-Based Sequence Mining with Multiple Support Thresholds Keles, Ilkcan; Ozer, Mert; Toroslu, İsmail Hakkı; Karagöz, Pınar (2014-09-19) Due to the increasing use of mobile phones and their increasing capabilities, huge amount of usage and location data can be collected. Location prediction is an important task for mobile phone operators and smart city administrations to provide better services and recommendations. In this work, we propose a sequence mining based approach for location prediction of mobile phone users. More specifically, we present a modified Apriori-based sequence mining algorithm for the next location prediction, which invo...
Use of mobile phones in language learning: Developing effective instructional materials SARAN, Murat; Çağıltay, Kürşat; Seferoglu, GÖLGE (2008-03-26) With its widespread use and its features and functions such as mobility, reachability, localization, and personalization, mobile phone technology offers a great potential in learning environments. With this consideration, our first and foremost aim in this study has been to make use of this profound interest and potential, and contribute to the efforts to enhance existing educational practices, particularly in the developing regions of the world. Therefore, we developed instructional materials to be deliver...
Cooperative Communications in Future Home Networks Genc, Zulkuf; Rizvi, Umar H.; Onur, Ertan; Niemegeers, Ignas (Springer Science and Business Media LLC, 2010-05-01) The basic idea behind cooperative communications is that mobile terminals collaborate to send data to each other. This effectively adds diversity in the system and improves the overall performance. In this paper, we investigate the potential gains of cooperative communication in future home networks. We derive analytical expressions for the error probability of binary phase shift keying (BPSK) signals over Nakagami-m fading channels in a multi relay communication network. Following to the analytical study, ...
An Analysis on user profiles and usage preferences for mobile application recommendations Ünal, Perin; Taşkaya Temizel, Tuğba; Eren, Pekin Erhan; Department of Information Systems (2015) In this thesis, we investigated the relationship between personality features and mobile technology use, particularly the use of traditional communication channels such as voice calls and SMS messaging and rapidly evolving mobile applications, specifically in communication and commerce domains. This was the first study to investigate the relationship between different personality features and different aspects of mobile technology use to this extent. The rapid growth in the mobile application market present...
Implementation of a wireless streaming system for universal multimedia access Unal, U; Akar, Gözde (2004-04-30) This document, describes a universal multimedia access system and its implementation details. In the context of this document, universal multimedia access means accessing multimedia content over ubiquitous computer networks, using different computing platforms. The computer networks involve both wired and wireless networks, and computing platforms involve wired PC's, mobile PC's and personal digital assistants (PDA). The system is built on client/server architecture. Video data is H.263 coded and carried ov...
