Side Channel: Bits over Interference
Found in: IEEE Transactions on Mobile Computing
By Kaishun Wu,Haoyu Tan,Yunhuai Liu,Jin Zhang,Qian Zhang,Lionel M. Ni
Issue Date:August 2012
pp. 1317-1330
Interference is a critical issue in wireless communications. In a typical multiple-user environment, different users may severely interfere with each other. Coordination among users therefore is an indispensable part for interference management in wireless...

By Wuman Luo,Haoyu Tan,Huajian Mao,Lionel M. Ni
Issue Date:July 2012
pp. 1-10
High-dimensional similarity join (HDSJ) is critical for many novel applications in the domain of mobile data management. Nowadays, performing HDSJs efficiently faces two challenges. First, the scale of datasets is increasing rapidly, making parallel comput...
 
On Packing Very Large R-trees
Found in: 2012 13th IEEE International Conference on Mobile Data Management (MDM)
By Haoyu Tan,Wuman Luo,Huajian Mao,Lionel M. Ni
Issue Date:July 2012
pp. 99-104
Many emerging mobile applications require analyzing large spatial datasets. In these applications, efficient query processing relies on spatial access methods such as R-trees. For datasets that are fairly static, R-trees are often built as a data loading p...
 
Chip Error Pattern Analysis in IEEE 802.15.4
Found in: IEEE Transactions on Mobile Computing
By Kaishun Wu, Haoyu Tan, Hoi-Lun Ngan, Yunhuai Liu,Lionel M. Ni
Issue Date:April 2012
pp. 543-552
IEEE 802.15.4 standard specifies physical layer (PHY) and medium access control (MAC) sublayer protocols for low-rate and low-power communication applications. In this protocol, every 4-bit symbol is encoded into a sequence of 32 chips that are actually tr...
 
DDC: A Novel Scheme to Directly Decode the Collisions in UHF RFID Systems
Found in: IEEE Transactions on Parallel and Distributed Systems
By Lei Kang, Kaishun Wu, Jin Zhang, Haoyu Tan,Lionel M. Ni
Issue Date:February 2012
pp. 263-270
RFID has been gaining popularity due to its variety of applications, such as inventory control and localization. One important issue in RFID system is tag identification. In RFID systems, the tag randomly selects a slot to send a Random Number (RN) packet ...

By Haoyu Tan, Lionel M. Ni, Wuman Luo
Issue Date:October 2012
pp. 2139-2143
During the past decade, various GPS-equipped devices have generated a tremendous amount of data with time and location information, which we refer to as big spatio-temporal data. In this paper, we present the design and implementation of CloST, a scalable ...
     
Exploration of ground truth from raw GPS data
Found in: Proceedings of the ACM SIGKDD International Workshop on Urban Computing (UrbComp '12)
By Haoyu Tan, Huajian Mao, Lionel M. Ni, Nong Xiao, Wuman Luo
Issue Date:August 2012
pp. 118-125
To enable smart transportation, a large volume of vehicular GPS trajectory data has been collected in the metropolitan-scale Shanghai Grid project. The collected raw GPS data, however, suffers from various errors. Thus, it is inappropriate to use the raw G...
