LORD: A Localized, Reactive and Distributed Protocol for Node Scheduling in Wireless Sensor Networks
The lifetime of wireless sensor networks can be increased by minimizing the number of active nodes that provide complete coverage, while switching off the rest. In this paper, we ...

Distributed sampling and reconstruction of non-bandlimited fields in sensor networks based on shift-invariant spaces
We use the theory and algorithms developed for so-called shiftinvariant spaces to develop a novel distributed architecture for sampling and reconstructing non-bandlimited fields i...

Visualisation of wormholes in underwater sensor networks: a distributed approach
: We propose a distributed mechanism, Dis-VoW, to detect wormhole attacks in under-water sensor networks. In Dis-VoW, every sensor reconstructs local network layout using multi-dim...

Distributed LCMV beamforming in wireless sensor networks with node-specific desired signals
We consider distributed linearly constrained minimum variance (LCMV) beamforming in a wireless sensor network. Each node computes an LCMV beamformer with node-specific constraint...

Robust Distributed Sensor Network Localization Based on Analysis of Flip Ambiguities
Abstract— A major problem in wireless sensor network localization is erroneous local geometric realizations in some parts of the network due to the sensitivity to certain distanc...
