We are pleased to present this special section of Transactions on Mobile Computing, which contains some of the best work presented at the Seventh Annual International Conference on Mobile Systems, Applications, and Services (MobiSys 2009). MobiSys is the premiere venue for publishing research results at the intersection of mobile computing and software systems. The program committee received 128 submissions and selected 26 of these to appear at the conference held in June 2009 in Krakow, Poland. After the conference, we invited the top few of these papers to submit an extended paper to this special section. The authors revised their papers based on both conference feedback and further research. These papers went through a subsequent round of reviews and modifications, with the final result being the versions included in this section.
Papers at the conference covered a wide breadth of topics, and the papers in this special section reflect that diversity. The first paper, “SPATE: Small-Group PKI-Less Authenticated Trust Establishment,” tackles the challenging problem of enabling a group of mobile computers users to establish a trusted relationship without the presence of trusted infrastructure. The next paper, “Design, Realization, and Evaluation of xShare for Impromptu Sharing of Mobile Phones,” provides a mechanism for a cell phone user to temporarily share his or her phone with other individuals while restricting the available functionality. The paper, “Fidelity-Aware Replication for Mobile Devices,” brings together research in the fields of data replication and fidelity adaptation to create a synchronization system that lets each device store data replicas that are best suited to its particular capabilities. The final paper, “WiFi-Reports: Improving Wireless Network Selection with Collaboration,” aims to improve WiFi access point selection by providing a collaborative service with good security and privacy properties that allows mobile users to learn about the performance of nearby access points.
