IP-Geolocation Mapping for Moderately Connected Internet Regions
Found in: IEEE Transactions on Parallel and Distributed Systems
By Dan Li,Jiong Chen,Chuanxiong Guo,Yunxin Liu,Jinyu Zhang,Zhili Zhang,Yongguang Zhang
Issue Date:February 2013
pp. 381-391
Most IP-geolocation mapping schemes [14], [16], [17], [18] take delay-measurement approach, based on the assumption of a strong correlation between networking delay and geographical distance between the targeted client and the landmarks. In this paper, how...
 
Design, Realization, and Evaluation of xShare for Impromptu Sharing of Mobile Phones
Found in: IEEE Transactions on Mobile Computing
By Yunxin Liu, Ahmad Rahmati, Hyukjae Jang, Yuanhe Huang, Lin Zhong, Yongguang Zhang, Shensheng Zhang
Issue Date:December 2010
pp. 1682-1696
Mobile phones are truly personal devices loaded with personal data such as photos, contacts, and call history. Yet it is often necessary or desirable to share our phones with others. This is especially true as mobile phones are integrating features convent...
 
SoftMAC: Layer 2.5 Collaborative MAC for Multimedia Support in Multihop Wireless Networks
Found in: IEEE Transactions on Mobile Computing
By Haitao Wu, Yunxin Liu, Qian Zhang, Zhi-Li Zhang
Issue Date:January 2007
pp. 12-25
In this paper, we present the challenges in supporting multimedia, in particular, VoIP services over multihop wireless networks using commercial IEEE 802.11 MAC DCF hardware, and propose a novel software solution, called Layer 2.5 SoftMAC. Our proposed Sof...

Benefitting from advanced web technologies like JavaScript, CSS3 and HTML5, current web applications can provide ever richer functionalities and user experiences, on both PC and mobile devices like tablet computers and smartphones. Furthermore, they can pe...
     
Content-based isolation: rethinking isolation policy design on client systems
Found in: Proceedings of the 2013 ACM SIGSAC conference on Computer & communications security (CCS '13)
By Helen J. Wang, Alexander Moshchuk, Yunxin Liu
Issue Date:November 2013
pp. 1167-1180
Modern client platforms, such as iOS, Android, Windows Phone, and Windows 8, have progressed from a per-user isolation policy, where users are isolated but a user's applications run in the same isolation container, to an application isolation policy, where...
     
DozyAP: power-efficient Wi-Fi tethering
Found in: Proceedings of the 10th international conference on Mobile systems, applications, and services (MobiSys '12)
By Guobin Shen, Hao Han, Qun Li, Yongguang Zhang, Yunxin Liu
Issue Date:June 2012
pp. 421-434
Wi-Fi tethering (i.e., sharing the Internet connection of a mobile phone via its Wi-Fi interface) is a useful functionality and is widely supported on commercial smartphones. Yet existing Wi-Fi tethering schemes consume excessive power: they keep the Wi-Fi...

MobiVMM: a virtual machine monitor for mobile phones
Found in: Proceedings of the First Workshop on Virtualization in Mobile Computing (MobiVirt '08)
By Cheol-Ho Hong, Chuck Yoo, Seehwan Yoo, Yongguang Zhang, Yunxin Liu
Issue Date:June 2008
pp. 1-5
Mobile phones have evolved into complex systems as they have more and more new applications built-in. As a result, they are less reliable and less secure than before. Virtual Machine Monitors (VMM) or hypervisors have been introduced to help the reliabilit...
