Secure communication protocol for wireless sensor networks

, 2010
We propose a new communication protocol for wireless sensor networks, allowing to make them secure with respect to malicious attacks. Compared to standard secure protocols (e.g., the IEEE 802.15.4 and the ZigBee), the one we propose allows to increase ...

Impact of moving target on underwater positioning by using state measurement

Internet of Things and Cyber-Physical Systems
The localization of moving targets in an underwater acoustic wireless sensor network (UAWSN) is inaccurate due to the various underwater forces (viscous, hydrodynamic forces, perturbation of underwater). The false measurements in the sensor network cause

Giant Anisotropic Spin Absorption in Chiral Hybrid Semiconductors

Advanced Materials, EarlyView.
Researchers uncover that chiral hybrid organic–inorganic semiconductors absorb spin differently depending on its polarization direction. This anisotropic spin absorption is primarily driven by the local symmetry breaking within the layered structure.

Secure Two-Party Distance Computation Protocols with a Semihonest Third Party and Randomization for Privacy Protection in Wireless Sensor Networks

International Journal of Distributed Sensor Networks, 2015
Scenarios in which two nodes who distrust each other in wireless sensor networks (WSNs) would like to know the distance between them are considered. The scenario is designed to protect the private information of WSNs, in this case each node's location ...
