Key research themes
1. How can USSD technology enhance location-based and context-aware mobile advertising accessible across diverse user devices?
This research focus area investigates the development of location-aware mobile advertising systems that leverage USSD technology to overcome limitations inherent to other platforms like GPS, Bluetooth, JAVA apps, WiFi, and WAP. The motivation is to make mobile advertising universally accessible regardless of device sophistication or network constraints, thereby broadening reach especially in low-resource settings. The key challenge is designing interactive, user-friendly systems using USSD menus combined with SMS for content delivery to enable effective, low-cost, location-based marketing.
Key finding: This paper proposes a comprehensive architecture for location-based mobile advertising systems using USSD for interactive menus and registrations and SMS for content delivery, addressing the accessibility issues of other... Read more
Key finding: This work develops a USSD real-time connection system combining mobile recharge services and surveys, underlining USSD’s strength as a widely accessible platform capable of running on both basic feature phones and... Read more
Key finding: Although this paper primarily focuses on UML and model-driven development, its insights into domain-specific modeling and precision in system design provide methodological foundations applicable to specifying USSD-based... Read more
2. What are the best approaches for applying USSD to data collection and academic administrative functions to improve accessibility and efficiency?
The theme explores how USSD can be leveraged as a low-cost, inclusive communication channel for data collection and academic administrative services such as student registration and employee leave management. Research focuses on replacing traditional paper-based or web-dependent systems with USSD platforms that are device-independent, faster, cost-effective, and capable of running on all GSM phones, thereby enhancing participation and reducing infrastructural constraints especially in developing regions.
Key finding: The paper develops a USSD-based system enabling secured, fast, and device-independent data collection that overcomes internet unavailability on classic mobile devices. It integrates dynamic question workflows and backend... Read more
Key finding: This research demonstrates the use of USSD as a complementary channel integrated with existing online registration systems to alleviate web access bottlenecks caused by high concurrent usage. The USSD platform provides... Read more
Key finding: The study implements a USSD-based employee leave management system replacing paper-based manual processes. It reports high user satisfaction due to improved speed, convenience, and user-friendliness, with 94% success rate in... Read more
3. How can USSD enable financial and agricultural information services to enhance inclusion for underserved populations?
This research theme addresses utilizing USSD to provide financial services such as banking and fund transfers, and agricultural advisories in underserved or rural regions where smartphone and internet penetration is low. USSD’s compatibility with basic mobile phones and regional language support makes it a critical platform for expanding digital financial inclusion and delivering timely agricultural weather and market information to farmers and tribal communities.
Key finding: The paper designs a toll-free USSD banking system incorporating voice recognition and IVRS modules with regional language options to facilitate secure financial transactions for tribal and hill station populations who lack... Read more
Key finding: The study develops a USSD-based agricultural communication system that delivers weather forecasts and agronomist advice to farmers via simple USSD menus, allowing farmers to plan ahead despite literacy and technology... Read more
Key finding: This paper proposes a USSD-based SMS information system to support e-governance in Bangladesh’s agricultural sector, aiming to overcome intermediaries’ monopoly and information asymmetry. USSD allows farmers to access market... Read more
