Active Application oriented vertical handoff in next generation wireless networks
Wireless Communications and Networking Conference, 2005Co-Authors: Wentsuen Chen, Yenyuan ShuAbstract:The coexistence of heterogeneous wireless networks providing service anywhere at anytime is an inevitable trend in the development of next-generation wireless data networks. Vertical handoff is the switching of the mobile terminal (MT) among different types of wireless networks. How and when to carry out vertical handoff directly affects the performance and quality of network services. In this paper, we propose a novel vertical handoff scheme in which the MT can request and initiate the handoff Actively, contrary to other schemes where the MTs participate passively during the handoff process. Our Active Application oriented scheme provides an efficient interface management for multi-interface MTs to reduce the power consumption caused by unnecessary interface activation. By treating the Application running in the MT as the main vertical handoff decision factor, the proposed scheme is able to switch the MT at the right time to the most suitable network to minimize the waste of network resources. Finally, simulation results are presented to show the improved performance over passive schemes.

CSCW - Increasing Collocated People's Awareness of the Mobile User's Activities: a Field Trial of Social Displays
Proceedings of the 19th ACM Conference on Computer-Supported Cooperative Work & Social Computing, 2016Co-Authors: Pradthana Jarusriboonchai, Aris Malapaschas, Thomas Olsson, Kaisa VäänänenAbstract:Many activities that have traditionally been performed with different dedicated physical artifacts are now done with personal mobile devices. Consequently, the privacy of mobile interfaces has hampered social observability and chances for serendipitous interactions. For example, reading an electronic newspaper with a mobile device does not allow the surrounding people to be similarly aware of the reader's activity as traditional newspapers. Social displays are additional displays on mobile devices providing the surrounding people with light-weight cues about the activities of the device user. We implemented a prototype that reveals the user's current Active Application and presents its name on an e-ink display on the backside of a mobile device. We conducted a ten-day field trial with 13 participants using the prototype. The results show that the prototype was able to increase awareness of users' mobile activities and occasionally triggered interactions with others, without significantly violating the sense of privacy.

a hybrid web recommender system based on q learning
ACM Symposium on Applied Computing, 2008Co-Authors: Nima Taghipour, Ahmad A KardanAbstract:Different efforts have been made to address the problem of information overload on the Internet. Recommender systems aim at directing users through this information space, toward the resources that best meet their needs and interests. Web Content Recommendation has been an Active Application area for Information Filtering, Web Mining and Machine Learning research. Recent studies show that combining the conceptual and usage information can improve the quality of web recommendations. In this paper we exploit this idea to enhance a reinforcement learning framework, primarily devised for web recommendations based on web usage data. A hybrid web recommendation method is proposed by making use of the conceptual relationships among web resources to derive a novel model of the problem, enriched with semantic knowledge about the usage behavior. With our hybrid model for the web page recommendation problem we show the apt and flexibility of the reinforcement learning framework in the web recommendation domain, and demonstrate how it can be extended in order to incorporate various sources of information. We evaluate our method under different settings and show how this method can improve the overall quality of web recommendations.
