Wireless Sensors Networks (WSNs) is the critical part of the Internet of Things (IOTs). However, most of the wireless sensors in WSNs also use batteries as their power supply. The finite battery life has limited the development and application of WSNs. The self-powering device could be a good solution, which performs both an energy harvester and wireless sense function. Vibrations with frequencies...
Wireless Sensor Networks (WSNs) have undergone rapid advancement over the past few decades. Typically, batteries power these wireless sensors. However, in many cases, battery life is preventing the WSNs from being widely applied. The power supply bottlenecks of WSNs would be solved by the self-powering sensors completely. As vibration energy is ubiquitous, energy harvesting from environment vibration...
For bearings-only target localization in passive sensor networks, a novel analysis approach based on fuzzy geometry is introduced to investigate the fuzzy measurability for a moving target in R2 space. The fuzzy analytical bias expressions are derived. And the interplay between fuzzy localization geometry and the fuzzy estimation bias for the case of fuzzy triangular grid deployment is analyzed in...
Because of sensors with different types and some other different characteristics in real deployment, there exist four kinds of interaction among sensors in information fusion for coverage analysis, including negative synergy, positive synergy, independency and interference. In order to handle the interaction properly, the discrete fuzzy measure theory is introduced to represent the interaction among...
For random deployment in sensor networks, there exists uneven node density, seriously reducing the network performance after clustering. The idea of the power control in CDMA is applied to handle the communication coverage control for clusters in wireless sensor networks. The cloud model-based uncertainty reasoning and control mechanism are introduced to adjust the transmit power adaptively to keep...
