An Algorithm for Distributed Beacon Selection
This paper investigates wireless sensor networks where a small percentage of nodes are assumed to know their location a priori. These reference nodes enable absolute localization ...

Beyond local optimality: An improved approach to hybrid model learning
Abstract-- Local convergence is a limitation of many optimization approaches for multimodal functions. For hybrid model learning, this can mean a compromise in accuracy. We develop...

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...

A 3-Approximation for Facility Location with Uniform Capacities
We consider the facility location problem where each facility can serve at most U clients. We analyze a local search algorithm for this problem which uses only the operations of ad...

Robust joint localization and time synchronization in wireless sensor networks with bounded anchor uncertainties
A unified framework to jointly solve the two problems of localization and synchronization at the same time is presented in this paper. The joint approach is attractive because it ...
