Secure Verification of Location Claims with Simultaneous Distance Modification
We investigate the problem of verifying location claims of mobile devices, and propose a new property called simultaneous distance modification (SDM). In localization protocols sat...

Probabilistic Continuous Update Scheme in Location Dependent Continuous Queries
It is difficult to maintain the exact location of mobile objects due to the limited resources in a mobile network. A consequence of this problem is that the update cost for a locat...

Space-efficient dynamic orthogonal point location, segment intersection, and range reporting
We describe an asymptotically optimal data-structure for dynamic point location for horizontal segments. For n line-segments, queries take O(log n) time, updates take O(log n) amo...
