Decentralized Utility-based Sensor Network Design
Wireless sensor networks consist of energy-constrained sensor nodes operating unattended in highly dynamic environments. In this paper, we advocate a systematic decentralized appro...

Mesh-Based Sensor Relocation for Coverage Maintenance in Mobile Sensor Networks
Abstract. Sensor relocation protocols can be employed as fault tolerance approach to offset the coverage loss caused by node failures. We introduce a novel localized structure, in...

A Generic Framework for Handling Uncertain Data with Local Correlations
Data uncertainty is ubiquitous in many real-world applications such as sensor/RFID data analysis. In this paper, we investigate uncertain data that exhibit local correlations, tha...

Randomized Robot-Assisted Relocation of Sensors for Coverage Repair in Wireless Sensor Networks
—In wireless sensor networks (WSN), stochastic node dropping and unpredictable node failure greatly impair coverage, creating sensing holes, while locally redundant sensors exist...

Tolerance of localization imprecision in efficiently managing mobile sensor databases
Query processing on mobile sensor networks requires efficient indexing and partitioning of the data space to support efficient routing as the network scales up. Building an index ...
